Development · Mobile app development
Mobile app development for iOS and Android, done once.
One codebase, two app stores. We build cross-platform apps that feel native, work offline and get through store review without drama.
In short
What is mobile app development?
Mobile app development is building software that runs on phones and tablets. technocity builds iOS and Android apps from a single Flutter or React Native codebase, covering design, offline data, push notifications, device features such as camera and location, the backend API, and App Store and Google Play submission, with crash reporting after launch.

The problems we solve
Two separate apps cost double to build and maintain
The app breaks when the network drops
Store rejections delay every release
No way to see crashes until users complain

Tools and technology
How it works
From first call to results
Pick the core journey
We choose the few screens that matter most and build those first.
Clickable prototype
You test a tappable prototype on your own phone before code starts.
Build and beta
Weekly builds go to TestFlight and Play internal testing for your team.
Store release
We prepare listings, privacy details and screenshots, then handle review feedback.
Questions
Common questions
Should I choose Flutter or React Native for my app?
Flutter and React Native both produce good iOS and Android apps from one codebase. Flutter gives very consistent visuals across devices, while React Native suits teams already using React on the web. We recommend one based on your existing team, design needs and device features.
How long does it take to build a mobile app?
A focused first version of a mobile app usually takes from eight to twelve weeks, including design, backend work, testing and store submission. Apps with complex offline sync, payments or hardware features take longer, so we plan a smaller first release and add features after launch.
Can a mobile app work without an internet connection?
Yes, a mobile app can work offline when it stores data on the device and syncs changes when the connection returns. We design conflict handling up front so records edited on two devices do not overwrite each other silently.
Do you publish the app to the App Store and Google Play?
Yes, technocity prepares and submits apps to both the Apple App Store and Google Play. We handle builds, signing, screenshots, privacy declarations and reviewer questions, and the listings stay under your own developer accounts so you keep full ownership.
Can you take over an existing app built by another team?
Yes, we can take over an existing app. We start with a code and dependency review, fix urgent crashes and build issues, then agree a plan for updates. You get a written summary of risks before any larger changes are made.
