iOS and Android app development

NextIQ Tech designs, builds and launches iOS and Android apps for customers and staff. We handle the app, the back end it needs, and the App Store and Google Play process, in the languages and regions your users are in.

Native or cross-platform?

The right approach depends on your budget, performance needs and timeline. We recommend one after discovery.

OptionTechnologiesGood fit when
Native iOSSwift, SwiftUIYou want the best Apple-platform experience, or deep device features
Native AndroidKotlin, Jetpack ComposeYou want the best Android experience across many devices
Cross-platformReact Native, FlutterYou want one codebase for both platforms and a faster, lower-cost start

  • Offline-first data and background sync.
  • Analytics, crash reporting and remote configuration.

From idea to the app stores

  1. Discover and design. User flows, wireframes and a clickable prototype you can test with real users.
  2. Build. Iterative development with a testable build every sprint.
  3. Test. Device testing, automated tests and beta releases through TestFlight and Google Play testing tracks.
  4. Launch. We prepare store listings, privacy disclosures and submissions to the Apple App Store and Google Play, using developer accounts that you own.
  5. Improve. We maintain the app through yearly iOS and Android updates and ship new features based on usage data.

Accessible, multilingual and global

We build with VoiceOver and TalkBack support, scalable text and good colour contrast. We localize the interface and the store listings into the languages you need, including right-to-left languages, and set up the back end in the country you specify. See multilingual software and global hosting.

Frequently asked questions

Should I build for iOS, Android or both?

Choose based on where your users are. In some markets one platform dominates. Many businesses launch on both using a cross-platform approach, then add native features where they matter.

How long does it take to build a mobile app?

A focused first version is often possible in a few months. The timeline depends on features, integrations, design and store review. We usually launch a smaller first release and expand.

Will you publish the app to the App Store and Google Play?

We prepare and submit the app. The developer accounts are owned by your business so you keep control of the listing.

Can the app support several languages?

Yes. We localize the app and the store listings, and support right-to-left languages such as Arabic and Hebrew.

Do you also build the back end and APIs?

Yes. We build the server, database and APIs the app needs, and can host them in the country you specify.
