App rescue

App stalled? Let's get it live.

You've invested in an app that still isn't live. The developer has gone quiet, the stores keep rejecting it, or it's been “nearly done” for months. Avantra takes over, tells you honestly where things stand, and gets it launched.

How a rescue works

  1. 1

    An honest assessment

    We look at what's really there: the code, the store accounts, the backend and exactly what's blocking launch.

  2. 2

    A straight answer

    Fix, finish or rebuild. We tell you which is the best way forward and why, even if the answer isn't the one you hoped for.

  3. 3

    Clear the blockers, then launch

    We fix what stops the release first, get it through store review, and polish once it's live.

  4. 4

    Keep it moving

    We take over development and support, so the product keeps improving instead of stalling again.

What we take over

Whatever state it's in. You keep ownership of your product, code and accounts, every change is visible in your project channel, and you're never locked in.

  • Any app or projectiOS, Android, web apps, platforms and back ends.
  • Someone else's codeUnfamiliar, undocumented or half-finished code.
  • Store submissionsRejections, review guidelines, compliance and resubmission.
  • Back ends and hostingDatabases, APIs, servers and the services behind the app.
  • ReleasesBuild signing, versioning and getting updates out safely.
  • Ongoing supportMonitoring, fixes and new features once it's live.

Rescue questions

Can you work with code someone else wrote?

Yes. Most rescues start with inherited code. We assess it calmly, keep what is sound, and fix or replace what is holding the product back.

Is it better to fix it or rebuild it?

It depends on what's there. Often the fastest route is fixing the blockers and releasing. Sometimes a focused rebuild is cheaper and more reliable in the long run. We'll recommend whichever is the best way forward and explain why.

Why does Apple or Google keep rejecting my app?

Usually because of specific review guidelines: missing privacy details, sign-in or payment rules, crashes during review, or content and compliance requirements for your category. We find the actual reasons and resolve them before resubmitting.

How long does a rescue take?

It depends on the state of the product. Paws In reached the App Store in about two weeks. You'll get a realistic estimate after the assessment, before any work begins.

Do we keep ownership of the app?

Yes. You own your product, code and accounts. We work in your accounts wherever possible, and you're never locked in.

What happens after it launches?

We can carry on with development, support and new features, or hand over cleanly to your team. Either way, you'll know exactly what you have.
