Pushbuild

Flutter apps for iPhone and Android, built and kept working.

Flutter lets one codebase run on iPhone and Android, which is why many small companies and agencies pick it. The hard parts come later: a build that will not compile after an upgrade, an App Store rejection, a crash on one model of phone, or a backend that was never finished. We build new Flutter apps, take over existing ones, and get releases through both stores. The scope is written down and agreed before we start.

Sound familiar?

What businesses with a Flutter app tell us before a project starts.

  • The app was built by a developer who has moved on.
  • Apple rejected our update and we do not understand why.
  • It crashes on some Android phones and we cannot reproduce it.
  • The app will not build since the last Flutter upgrade.
  • We need payments, maps or push notifications added.

What we build

Each one is a working piece you can open and check when it's done.

Take over an existing app

The code reviewed, dependencies upgraded, the build repaired for current iOS and Android, and a short report on what we found.

Store releases

Signing, store listings, privacy details and rejection responses handled so the app gets approved.

Mobile apps for iPhone and Android

Crash and bug repairs

Crash reporting added, the top crashes traced and repaired, and tests added where it keeps breaking.

Example projects

Illustrations of the shape of the work, not past clients. Yours gets its own written scope.

Example project

Rejected update

Example: a gym's class-booking app was rejected for its account deletion flow. The flow is added and the update resubmitted.

Flutter, App Store Connect

Example project

Abandoned project

Example: an agency inherits a half-finished Flutter app for a client. It is upgraded, the backend finished in Firebase, and released.

Questions people ask first

Can you work on a Flutter app someone else built?

Yes. We start by reviewing the code and getting it to build, then tell you what state it is in before doing more.

Do we need a Mac and developer accounts?

You need your own Apple and Google developer accounts so the app stays in your name. We handle the build side.

Flutter or a web app?

If people use it on the go, need the camera, notifications or offline use, an app helps. If not, a web app that works on phones can be simpler. We say which in the scope.

How do we start?

Send the store link or the repository and what is wrong. We reply with questions or a written scope.
