Take Over App Project From Another Developer | Appverra
+
App Rescue Service

Your Developer Left.
We Pick Up Where They Stopped.

Appverra is a mobile app development company that has shipped 150+ apps for 700+ customers. Our apps have millions of downloads. We specialize in taking over projects that other developers abandoned, botched, or could not finish. We assess what you have, tell you honestly whether to continue or rebuild, and ship the working product you were promised. Fixed-bid pricing. No hourly billing. Three co-founders — the person you talk to is the person reading your code.

How Projects
End Up Here

None of these are your fault. They happen to good founders with real products and real budgets. The common thread: you trusted someone with your build and they did not deliver.

Developer Quit Mid-Project

They took on too much work. They got a full-time offer. They ghosted. Whatever the reason — you have a half-built app, source code you cannot evaluate, and a deadline that did not move.

Offshore Team Delivered Garbage

The app technically runs but it crashes, the code is unmaintainable, every feature takes 3x longer than it should, and the offshore team keeps asking for more budget without shipping results.

Agency Missed Every Deadline

Six months past the original timeline. Demo after demo that does not work. The scope keeps growing and the delivery date keeps moving. You fired them but the app is 60% done.

No-Code Hit Its Ceiling

You built an MVP on FlutterFlow, Bubble, or Adalo. Users loved it. Now you need features the platform cannot support — custom integrations, performance, or scalability that requires real code.

Co-founder / CTO Left

Your technical co-founder departed. The codebase is live and generating revenue but nobody left on the team can maintain it. You need someone to take ownership immediately.

Freelancer Disappeared

The Upwork contractor stopped responding. You have a repo, maybe some documentation if you are lucky, and an app that is 70% done. You need someone to finish what they started.

Our Takeover
Process

Five steps from broken to shipped. We are transparent at every stage because you have already been burned by opacity.

1

Emergency Intake

30-minute call within 24 hours of contact. You tell us what happened, what you have (repo, designs, docs), and what the deadline is. Free — no obligation.

2

Code Audit

We review the existing codebase in 5 business days. Architecture grade. Severity-ranked issues. Fix-or-rebuild verdict. You get a written report you can share with anyone. $2,997 fixed price.

3

Honest Verdict

We tell you one of three things: (A) this code is fixable — here is the cost, (B) rebuild these modules, keep those — here is the cost, or (C) start over — here is why. No sugarcoating.

4

Fixed-Bid SOW

Whether we are continuing the existing build or rebuilding — you get a fixed price and timeline. No hourly. No retainers. No scope creep billing. The number you sign is the number you pay.

5

Ship

We build it. We ship it to the App Store and Play Store. We provide 30-90 days of post-launch support depending on tier. You own the code. You own the accounts. It is yours.

+

No-Downtime Transition

If your app is live and generating revenue, we never take it offline. We work in parallel — new code, new features, migrate data — and cut over when everything is tested. Zero user disruption.

Honest Answers

How quickly can you start?

Intake call within 24 hours. Code audit starts the day we receive repo access. If this is genuinely urgent — your app is live and broken — we prioritize rescue projects ahead of new builds.

What if I do not have the source code?

If the app is on the App Store or Play Store, you still own the listing. If you have the developer account credentials, we can decompile and assess what is recoverable. If the previous developer is holding your code hostage, we can advise on legal options and quote a rebuild from scratch.

What technologies can you take over?

Flutter, React Native, Swift, SwiftUI, Kotlin, Jetpack Compose, Ionic, Xamarin. If the app was built in something we do not support, we will recommend a rebuild in a modern stack and explain the cost difference between continuing in the legacy framework vs migrating.

Will my users experience downtime during the transition?

No. We work in parallel — building the new code while the existing app continues running. We cut over only when everything is tested. For live apps generating revenue, we treat continuity as non-negotiable.

What if the audit says rebuild but I cannot afford $29,997?

We scope honestly. If a rebuild is the right call but the full budget is not there today, we can stage it: rebuild the critical modules first ($14,997), ship a working version, and phase the rest. We would rather help you ship something real than sell you something you cannot execute.

How is this different from just hiring a new developer?

A new developer inherits your mess and guesses. We start with a structured audit that documents every issue before writing a single line. You get a fixed-bid quote instead of hourly uncertainty. And we have done this for dozens of founders — we know where broken projects hide problems that a solo hire would not catch until month three.
