/// Honest exclude

We'd rather tell you on the call than at week six.

A native-only build with separate Swift + Kotlin teams — we use cross-platform for cost reasons; we'll be honest if your app needs native.

Free of app-store fees — Apple Developer £79/yr and Play Console £20 one-off are on you.

Submission-guaranteed — Apple's review process is theirs, not ours. We've shipped through it before.

/// FAQ

Do we own the app code?+

Yes, from day one. Code in your repo. Apple + Play accounts are yours. We don't host you.

What if we already have a website — can it become an app?+

Often, yes. We wrap the web app in a native shell, add push, offline and biometric. Quicker and cheaper than rebuilding.

Can you update the app every month?+

Retainer engagements include monthly updates. OTA delivery means most don't need a store re-review.
