iOS and Android App Development

Turn Your Mobile App Idea Into a Real Product

A well-designed mobile app can help your business serve customers, streamline operations, create a new source of revenue, or bring an original product idea to market.

I provide iOS and Android mobile app development services for businesses, entrepreneurs, and organizations in Spokane, Washington. From early planning and interface design to development, testing, App Store submission, Google Play deployment, and ongoing updates, I can help guide your app from concept to launch.

Whether you need a customer-facing mobile app, an internal business tool, a subscription-based product, an e-commerce application, or a simple first version of a startup idea, I develop custom solutions around your goals, users, budget, and long-term plans.

Every app project begins with a practical question: what should this app help the user accomplish?

From there, I help define the features, select the right technology, organize the development process, and build an application that is functional, understandable, and ready for real-world use.

Custom Mobile App Development for Spokane Businesses

Mobile apps can support many different business goals.

Some businesses need an app that gives customers easier access to their services. Others want to automate internal workflows, sell digital products, offer memberships, build a game, or launch a new technology company.

I develop custom mobile applications that can help businesses:

• Improve customer convenience

• Offer mobile booking or scheduling

• Sell products or services

• Deliver digital content

• Manage customer accounts

• Support loyalty programs

• Accept subscriptions or in-app purchases

• Send push notifications

• Collect information in the field

• Provide employee tools

• Track activity or progress

• Connect customers with a service

• Build an original app-based business

• Replace slow or outdated manual processes

The application is planned around your specific users and requirements rather than being forced into a generic template.

iOS App Development

I provide custom iOS app development for Spokane businesses and entrepreneurs, including applications designed for iPhone and iPad.

Depending on the project, iOS applications can be developed using Apple technologies such as Swift and SwiftUI.

Native iOS development can provide:

• Strong performance

• Smooth Apple platform integration

• Access to device capabilities

• Modern interface options

• Support for Apple services

• Compatibility with App Store distribution

• A consistent experience across supported Apple devices

iPhone App Development

An iPhone app can provide customers or employees with convenient access to your products, services, information, or business tools.

iPhone app projects may include:

• Customer account apps

• Booking applications

• Subscription platforms

• Games and entertainment apps

• Educational apps

• Loyalty and rewards apps

• Productivity tools

• E-commerce applications

• Business dashboards

• Health and activity tracking tools

• Community applications

• Content and media apps

• Internal employee tools

The app can be designed specifically for iPhone or adapted to work across multiple Apple screen sizes.

iPad App Development

iPad applications can be useful for businesses that need a larger touchscreen interface.

Potential iPad uses include:

• Point-of-sale tools

• Field service applications

• Inventory systems

• Digital forms

• Customer check-in

• Restaurant or retail interfaces

• Training applications

• Sales presentations

• Data dashboards

• Kiosk applications

• Educational tools

• Internal business operations

An iPad app can be developed as part of the same Apple project or designed as a separate experience when the workflow requires it.

Android App Development

I also provide Android app development for Spokane-area businesses, helping companies reach users across a wide range of Android phones and tablets.

Android development may use technologies such as Kotlin and Jetpack Compose, depending on the application’s needs.

Android applications can support:

• Google Play distribution

• Phone and tablet layouts

• Device-specific features

• Push notifications

• Google service integrations

• Customer account systems

• Subscription and purchase functionality

• Location-based tools

• Camera and media features

• Business workflow applications

Because Android devices vary widely in screen size, hardware, and operating system version, careful testing is an important part of development.

The app should be designed to remain usable and consistent across the devices your customers are most likely to use.

Cross-Platform Mobile App Development

Some projects benefit from using one shared codebase for both iOS and Android.

Cross-platform development can reduce duplication while allowing the app to be distributed through both the Apple App Store and Google Play.

Depending on the project, cross-platform technologies may include:

• Flutter

• React Native

• Shared web technologies

• Hybrid application frameworks

• Platform-specific integrations where needed

Cross-platform development can be a good fit when:

• The iOS and Android experiences will be similar

• The app needs to launch on both platforms

• The project has a focused budget

• Shared development speed is important

• The app does not require extensive platform-specific features

• The business wants one core application to maintain

Native development may be the better choice when the app requires maximum performance, deep platform integration, advanced animations, or highly specialized device capabilities.

I can help evaluate which approach makes the most sense before development begins.

Mobile App Strategy and Planning

A successful mobile app begins with careful planning.

Building every possible feature at once can increase cost, slow development, and make the application harder to use.

I help define a focused product plan based on:

• The problem the app should solve

• The intended users

• The primary user journey

• Required features

• Optional future features

• Revenue model

• Technical requirements

• Data storage needs

• External integrations

• Security considerations

• App Store requirements

• Long-term maintenance

This planning process helps separate essential launch features from ideas that can be added later.

Minimum Viable Product Development

A minimum viable product, commonly called an MVP, is the first functional version of an application that includes the features necessary to test the main idea.

An MVP can help you:

• Launch sooner

• Reduce initial development cost

• Test customer interest

• Gather user feedback

• Validate the business model

• Identify usability problems

• Demonstrate the product to investors or partners

• Prioritize future development

An MVP should not be unfinished or unreliable. It should be a focused version of the product that performs its most important function well.

I can help define which features belong in the initial release and which ones should be saved for future updates.

Mobile App User Interface and Experience Design

A mobile app should be easy to understand from the moment it opens.

Good interface design helps users know:

• Where they are

• What they can do

• What action to take next

• How to correct a mistake

• How to find important information

• Whether an action was completed successfully

Mobile app design may include:

• Screen layouts

• Navigation structure

• Buttons and controls

• Forms

• Menus

• Color and typography

• Loading states

• Error messages

• Empty states

• Onboarding screens

• Account setup

• Calls to action

• Accessibility considerations

The goal is to create an interface that feels clear and consistent rather than overwhelming users with unnecessary options.

App Prototypes and Wireframes

Before development begins, it can be helpful to map out the application through wireframes or an interactive prototype.

Wireframes show the structure and function of each screen without requiring the entire app to be built.

A prototype can help:

• Clarify the app concept

• Review navigation

• Identify missing screens

• Test the user journey

• Collect stakeholder feedback

• Reduce expensive changes during development

• Explain the project to investors or partners

• Confirm priorities before coding begins

Prototyping is especially valuable for larger applications, unfamiliar workflows, or projects involving multiple decision-makers.

Backend Development and Databases

Many mobile apps require a backend system to store information and support communication between users, devices, and business systems.

Backend development may include:

• User accounts

• Databases

• Cloud storage

• Application programming interfaces

• Administrative dashboards

• Authentication

• Payment records

• User-generated content

• Product information

• Messages

• Progress tracking

• Analytics

• Subscription status

• Notification management

Depending on the project, backend services may use:

• Firebase

• Supabase

• Custom APIs

• SQL databases

• Cloud hosting

• Serverless functions

• Existing business systems

The backend should be designed around the app’s expected usage, security requirements, and long-term growth.

User Accounts and Authentication

Many applications need a secure way for users to create an account and access their information.

Account features may include:

• Email and password login

• Social sign-in

• Apple Sign In

• Google Sign-In

• Password reset

• Email verification

• Profile management

• Guest accounts

• Role-based permissions

• Administrative access

• Account deletion

• Session management

The authentication method should be appropriate for the type of information the application stores.

Apps that process sensitive or private information may require stronger account controls and security measures.

Mobile App Integrations

A mobile application often becomes more useful when connected to other tools or services.

I can help integrate mobile apps with:

• Websites

• Business databases

• Customer relationship management systems

• Payment processors

• Scheduling platforms

• E-commerce systems

• Email marketing platforms

• Analytics tools

• Mapping services

• Cloud storage

• Social login providers

• Artificial intelligence services

• Third-party APIs

• Existing business software

For example, a mobile app could allow a customer to schedule a service, send the booking to your existing calendar, update a customer record, process payment, and send confirmation automatically.

Payment Processing and In-App Purchases

Mobile apps can generate revenue through several different payment models.

Potential options include:

• One-time app purchases

• In-app purchases

• Consumable purchases

• Non-consumable upgrades

• Monthly subscriptions

• Annual subscriptions

• Paid memberships

• Premium content

• Feature unlocks

• Digital products

• Physical product purchases

• Service payments

Apple and Google have specific rules for payments made inside mobile applications, particularly when selling digital content or features.

I can help structure the app’s purchase flow, connect payment systems, and prepare the required products for submission.

Subscription App Development

Subscriptions can create recurring revenue when an application provides ongoing value.

Subscription-based apps may offer:

• Premium features

• Ad-free access

• Additional content

• Cloud storage

• Advanced reporting

• Exclusive tools

• Membership benefits

• Continued access to a service

• New monthly content

• Multiple subscription levels

A subscription system may include:

• Free trials

• Monthly and annual options

• Upgrade screens

• Restore-purchase functionality

• Subscription status checks

• Renewal messaging

• Account management

• Feature access controls

The app should clearly explain what the user receives and how the subscription works.

Push Notifications

Push notifications allow an app to communicate with users even when the application is not open.

Notifications may support:

• Appointment reminders

• New content alerts

• Promotional messages

• Account activity

• Order updates

• Streak reminders

• Event reminders

• Customer service updates

• Location-based messages

• Subscription notices

Notifications should be useful and relevant.

Sending too many messages can cause users to disable notifications or uninstall the application, so the system should be designed with timing, frequency, and user preferences in mind.

Location, Camera, and Device Features

Mobile applications can use built-in device capabilities when those features support the app’s purpose.

Potential features include:

• GPS and location services

• Maps

• Camera access

• Photo uploads

• Barcode scanning

• QR code scanning

• Microphone access

• Local notifications

• Biometric authentication

• File access

• Contacts

• Calendars

• Motion data

• Offline storage

Apps must request permission before accessing many device features.

Permission requests should clearly explain why the information is needed and should only appear when the feature is relevant.

Artificial Intelligence in Mobile Apps

Artificial intelligence can add new functionality to mobile applications.

AI-powered mobile features may include:

• Chat assistants

• Content recommendations

• Image analysis

• Text generation

• Document summaries

• Voice transcription

• Search tools

• Personalized learning

• Customer support

• Data classification

• Automated form completion

• Intelligent notifications

• Business workflow assistance

AI features should be designed around a useful task rather than added as a novelty.

I can help connect mobile applications to AI services while considering accuracy, privacy, cost, and appropriate user controls.

Game and Entertainment App Development

Mobile games and entertainment applications can range from simple casual experiences to larger systems with accounts, achievements, daily challenges, purchases, and online features.

Game app development may include:

• Puzzle games

• Trivia apps

• Card games

• Arcade-style games

• Daily challenge apps

• Educational games

• Progress systems

• Streak tracking

• Scoreboards

• Achievements

• Unlockable content

• In-app purchases

• Advertisements

• Subscription features

A mobile game should be designed around a clear gameplay loop that encourages users to understand the objective, complete a session, and return later.

Business and Productivity App Development

Mobile applications can also improve internal business operations.

Internal app projects may include:

• Employee checklists

• Inventory tools

• Field service applications

• Inspection forms

• Sales tracking

• Customer intake

• Job-site documentation

• Time tracking

• Delivery management

• Expense reporting

• Training applications

• Data collection

• Approval workflows

• Internal communication

A custom business app can replace spreadsheets, paper forms, email chains, and disconnected processes with one structured mobile workflow.

E-Commerce Mobile Apps

An e-commerce application can give customers another way to browse and purchase products.

E-commerce features may include:

• Product catalogs

• Search and filtering

• Customer accounts

• Shopping carts

• Checkout

• Order history

• Saved products

• Push promotions

• Loyalty features

• Product reviews

• Inventory updates

• Shipping information

• Local pickup

• Payment processing

An e-commerce app should connect with the business’s existing website, inventory system, or order management platform when possible.

Maintaining separate product information in multiple systems can create unnecessary work and inconsistencies.

App Store and Google Play Submission

Completing development is only part of launching a mobile application.

The app must also be prepared for review and submitted to the appropriate marketplace.

I can help with:

• Apple Developer account setup

• Google Play Console setup

• App identifiers

• Certificates and signing

• Provisioning profiles

• Store listing preparation

• App descriptions

• Search keywords

• Privacy information

• Age ratings

• Screenshots

• Internal testing

• TestFlight distribution

• Google Play testing tracks

• Submission troubleshooting

• Review response guidance

Apple and Google review apps for technical, privacy, content, and policy requirements.

Planning for these requirements early can reduce delays during submission.

App Store Optimization

App Store optimization, often called ASO, helps an application become easier to discover within the Apple App Store and Google Play.

App Store optimization may include:

• App name strategy

• Subtitle development

• Keyword research

• App descriptions

• Category selection

• Screenshot planning

• Preview video recommendations

• Icon review

• Feature messaging

• Competitor research

• Review strategy

• Store listing updates

App Store visibility depends on many factors, including relevance, downloads, engagement, ratings, and competition.

A clear listing can improve the likelihood that users understand the app and choose to install it.

Mobile App Advertising and Analytics

Mobile applications can include analytics and advertising tools to help measure performance and support monetization.

Analytics may track:

• App installs

• Active users

• Screen views

• Feature usage

• Purchases

• Subscription conversions

• Retention

• Crashes

• User journeys

• Marketing campaign performance

Advertising integrations may include:

• Banner ads

• Interstitial ads

• Rewarded video ads

• Native ads

• App-install campaigns

• Ad network mediation

Advertising should be placed carefully so it does not make the app frustrating or difficult to use.

Testing and Quality Assurance

Mobile applications should be tested before release across realistic devices and scenarios.

Testing may include:

• Feature testing

• Interface testing

• Account creation

• Login and password recovery

• Payment testing

• Subscription testing

• Notification testing

• Offline behavior

• Error handling

• Screen-size testing

• Performance testing

• Device permission testing

• App Store purchase environments

• Crash monitoring

Testing helps identify problems before they affect real users.

No application can be guaranteed to be completely free of defects, but a structured testing process reduces avoidable issues and improves launch quality.

Mobile App Security and Privacy

Applications that collect user information should be designed with privacy and security in mind.

Depending on the project, this may include:

• Secure authentication

• Encrypted connections

• Access controls

• Protected API keys

• Data validation

• Database security rules

• Account deletion

• Limited data collection

• Privacy disclosures

• Permission management

• Secure payment processing

• Session controls

• Error logging without exposing private data

The app should only request and store information that is necessary for its intended purpose.

Businesses may also need a privacy policy, terms of service, data deletion process, and other disclosures before launching.

App Maintenance and Updates

Mobile app development does not always end at launch.

Apple, Google, device manufacturers, software libraries, and third-party services continue to change over time.

Ongoing maintenance may include:
