02 Who it's for
Who it's for
01
You know you need an app, not which kind.
Native iOS and Android, or one cross-platform codebase — the right answer depends on your budget, your timeline, and how deep you need to go into each platform's own features.
02
You're worried about app store rejection.
Apple and Google reject apps for reasons that have nothing to do with code quality. We plan for their review guidelines before submission, not after a rejection email.
03
You need someone to own it after launch.
An app that ships and then has no owner is an app that breaks quietly. Maintenance & Support exists specifically for what happens after the store listing goes live.
03 What's included
What's included
Platform strategy
A written recommendation — native, cross-platform, or both — based on your budget, timeline, and feature list, not a default answer.
UI built for each platform's conventions
Interfaces that feel native to iOS and Android, not one design awkwardly stretched over both.
Core app development
The build itself, in Swift/Kotlin for native or a shared cross-platform codebase, matched to the platform strategy.
API & backend integration
Connections to your existing backend, or a lightweight one built alongside the app where none exists.
App store submission
Both store listings prepared and submitted, with the review guidelines accounted for in the build, not bolted on after a rejection.
Source code & signing credentials
Full source code and your own developer account credentials, handed over on final payment.

Native or cross-platform — which should I pick?
Cross-platform (React Native) is faster and cheaper to ship and covers most apps well. Native is worth the extra cost when you need heavy device features, top-tier performance, or platform-specific UI that cross-platform frameworks handle awkwardly. We give you a direct recommendation, not a shrug.

Frequently asked questions
Native or cross-platform — which should I pick?
Cross-platform (React Native) is faster and cheaper to ship and covers most apps well. Native is worth the extra cost when you need heavy device features, top-tier performance, or platform-specific UI that cross-platform frameworks handle awkwardly. We give you a direct recommendation, not a shrug.
What if Apple or Google rejects our app?
We account for the current review guidelines during the build, which prevents most rejections. If one happens anyway, resolving it is included in the launch step — it's not a new invoice.
Who maintains the app after it’s live?
You, or us on a Maintenance & Support retainer — including apps we didn’t build. OS updates alone are enough reason most teams keep a support contract running.
Do we own the App Store / Play Store listing?
Yes — we build in your developer accounts, not ours, so you keep full control of the listings from day one.
