Mobile App Development
iOS, Android and cross-platform apps shipped to the stores.
HandsOnTech mobile development covers native iOS and Android, Flutter and React Native cross-platform, and HIPAA-aware healthcare apps — with store submission, crash monitoring and post-launch releases included in every engagement.
Five mobile specialties, one standard: a working build on your phone every two weeks, honest platform recommendations with the trade-off math attached, and a team that stays past launch day.
Shipped to the stores, not just to staging
The distance between “the app works on the demo phone” and “the app is live in both stores with monitoring” is where most mobile projects quietly die. Store review rejections, crash spikes on mid-range Android devices, push certificates, privacy labels — we carry projects through all of it, because a build that never clears App Store review is a very expensive prototype. TestFlight builds land on your phone from week four, and both store submissions — with the review-cycle management they require — are included in every engagement.
Native, Flutter or React Native — chosen by the project
iOS-first consumer apps with heavy platform integration get native Swift. Android fleets across mixed hardware get Kotlin with a real device-matrix test plan. Design-led products that need both stores on one budget get Flutter; teams with JavaScript talent that want shared code get React Native. Healthcare apps get HIPAA-aware architecture from the first data-flow diagram. The framework question has no universal answer — only a per-project one, and ours comes in writing with the reasoning attached so your own engineers can challenge it.
