Mobile apps, shipped to stores—
not just designed in Figma.
We build iOS, Android, Flutter and React Native apps end-to-end — design, code, QA, store submission, and the long tail of maintenance. 140+ apps in the App Store and Play Store, written by the same engineers who’ll be on your kickoff call.
- 01
Agile, not theatrical
Certified scrum masters. Two-week sprints. Loom walkthroughs every Friday. You sign off on Monday — or we adjust before Monday.
- 02
Code your next engineer can read
Clean, typed, lint-clean. We write the kind of code we’d be happy to inherit. Repos handed over with docs and a runbook.
- 03
QA before users see it
Manual + automated test plans. Device labs for iOS and Android. Crash-free rate is a launch criterion — not a wish.
Android development
Custom builds, wearables, TV, tablet, SDK — and the kind of QA that keeps your Play Console clean.
Android is the platform we’ve shipped most. A decade of releases, dozens of OEMs, three Material redesigns — we’ve seen the regressions before you hit them.
Full-cycle: UI/UX, Kotlin code, Jetpack libraries, Play Store submission, post-launch metric tracking. You get an app you can run for five years, not a prototype to throw away.
- 01Custom Android app development
- 02Android wearables (Wear OS)
- 03Android TV apps
- 04Tablet & foldable layouts
- 05Android SDK development
- 06App porting from legacy code
- 07Support & maintenance contracts
iOS development
Sleek, fast, App-Store-clean iPhone and iPad apps — from someone who’s actually read the latest Human Interface Guidelines.
We build iOS the way Apple wants iOS built — SwiftUI where it earns its place, UIKit where it has to. WatchOS and tvOS when you need them.
Apple review failures cost weeks. We’ve submitted enough apps to know which rejection codes you actually have to fear and which ones are reviewer noise. Yours ships on time.
- 01Custom iPhone apps
- 02iPad & Stage Manager layouts
- 03Apple Watch apps
- 04Apple TV apps
- 05iOS SDK development
- 06App porting & modernisation
- 07Long-term support contracts
Flutter development
One codebase. Pixel-perfect on iOS and Android. Used when the app is the product and you can’t afford two teams.
Flutter is the right call when your team is small, your design ambitions are large, and you want one engineer to ship features to both stores in the same sprint.
We use Flutter for fintech, social, and dashboard-style apps where motion and consistency matter. We don’t use it where you need deep platform-native API access — we’ll tell you when that’s the case.
- 01Flutter app development
- 02Flutter UI/UX systems
- 03Flutter for web
- 04Custom plugins
- 05Native ↔ Flutter migration
- 06Bridge to existing native code
- 07Support & maintenance
React Native development
When you already have a React web team, share the work. Native components, one codebase, real performance.
React Native lets a web team ship a real native app without learning two new languages. We use it when your engineering org is JS-heavy and you want to amortise the team.
We’ve migrated apps from old hybrid stacks (Cordova, Ionic) to RN and watched their App Store ratings climb. Native modules where we need them, JS where we don’t.
- 01React Native app development
- 02Native module bridges
- 03Hybrid → RN migration
- 04RN SDK development
- 05Performance profiling & tuning
- 06App maintenance & support
Six steps from kickoff to store.
Discovery
30-min call. We learn your product, users, timeline. You get a fixed price.
UX & UI
Wireframes week 1. High-fidelity screens by end of week 2. You sign off in Figma.
Build
Two-week sprints. Builds on TestFlight and Play Internal every Friday.
QA
Device labs, manual + automated. Crash-free rate target hit before submission.
Store submission
We file. We handle reviewer back-and-forth. You announce when it’s live.
Maintenance
Optional retainer. OS updates, library bumps, occasional new features.
Reasons clients actually cite in the call.
- 01Expertise
Decade-deep on each platform. The engineer on your call has shipped your kind of app before.
- 02Agile
Sprints are real, not a status meeting. You see weekly builds on TestFlight from week three.
- 03Architecture
Boring, hireable stack choices. Easy to hand off when you outgrow us — we encourage it.
- 04QA
Crash-free rate is a launch criterion. Device lab covers the eight devices that catch 90% of bugs.
- 05Comms
Loom walkthroughs every Friday. Slack channel shared. Single PM, not a chain.
- 06Ethics
We tell you when something isn’t worth building. We’ve cancelled scope mid-project before.
- 07NDA
Strict NDA on every engagement. Source committed to your repo, not ours.

Our Recent Case Studies
Latest notes from the team.
Questions before the call.
What types of mobile apps do you build?+
Native iOS (Swift / SwiftUI), native Android (Kotlin / Jetpack Compose), and cross-platform via Flutter or React Native. We also maintain a handful of legacy Cordova / Ionic apps and migrate them out when it’s the right call.
What is a mobile app development service exactly?+
We take a product from concept to App Store and Play Store. That covers UX, UI, native code, backend integration, QA, store submission, and ongoing maintenance. Pick the stages you need; we don’t insist on the full menu.
Native or cross-platform — which one should I pick?+
Native when you need deep platform APIs, custom hardware, or AR/ML on-device. Cross-platform when your team is small and the app is mostly UI. We tell you which one your project is on the first call — based on your features, not on what we want to sell.
How do I actually engage with iTechNotion?+
30-min call. We listen, then propose a fixed-price scoping engagement (one to two weeks) that ends with a detailed spec and a launch date. If we’re not the right team, we’ll say so.
How long does it take to build a mobile app?+
Three to nine months depending on scope. A simple MVP (auth, profile, one core flow) is 8–12 weeks. A regulated app with payments, video, and multi-role access is 5–8 months. We’ll give you a real date on the call.
Got a mobile app
to ship?
30-min call. We scope your project, give you a fixed price and a real date. No hourly billing, no surprise extras.
