Your app is losing customers. We can fix it in weeks, not months.
Your customer or operations app is broken, slow, or the previous vendor walked away. We stabilize critical paths, fix integrations, and get the app back to production-grade — without rebuilding from scratch.
Fast fixes · Clear plan · No wasted time
Common business-app stabilization scenarios
The patterns we see most often when a business asks us to take over an existing app:
-
close
Your previous vendor disappeared, stopped responding, or quietly raised rates beyond what's reasonable
-
close
iOS or Android crashes are spiking after a recent OS update, and your team can't explain why
-
close
Your POS, CRM, or accounting integration breaks every few weeks and no one owns the fix
-
close
Performance has degraded — slow cold starts, sluggish lists, customers complaining about speed
-
close
The codebase is undocumented, the original team is gone, and you can't safely make any changes
An app that's losing customers and bleeding revenue is a business problem — not a development problem. We fix the business problem first.
Diagnose, stabilize, hand back a production-grade app.
Velzosoft audits, stabilizes, and rebuilds critical paths — without starting from scratch. We're not interested in convincing you to throw away working code. We fix what's actually broken.
Crash & bug elimination
Root-cause fixes for the bugs your customers actually report — not symptom patches.
Performance restoration
Cold-start optimization, list-rendering fixes, image pipeline tuning — measurable wins on real devices.
Integration repair
Fix and harden POS, CRM, accounting, and payment integrations that are failing intermittently.
Codebase audit & cleanup
Refactor without breaking — leaving you with documented code your next team can actually build on.
OS-version compatibility
Bring the app current with the latest iOS and Android releases. No more surprise crashes after Apple ships.
Ongoing ownership
If you want, we keep the relationship — monthly retainer covers OS updates, integration changes, and new feature work.

Fixed scope. Fixed price. Before we touch your code.
App stabilization engagements are fixed-price, scaled to the size of the existing codebase and the depth of the issues. We assess first, then quote — you approve before any work begins.

Most stabilization engagements complete in 2–4 weeks. Larger codebases or rebuild-grade work scoped separately.
Frequently Asked Questions
Yes. We specialize in improving and fixing existing projects — that's the whole point of App Rescue.
Not always. We only rebuild if it's necessary — most of the time, we can fix and refactor what's already there.
Most rescue projects take 2–4 weeks depending on the complexity of the issues and the state of the codebase.
We primarily work with Flutter on the mobile side and modern backend systems (Node, Python, Go). If you're on a different stack, tell us and we'll be honest about fit.
Tell us what's broken.
We'll review your app and give you a problem breakdown, fix strategy, and fixed-price quote. No commitment, no obligation. Takes less than 60 seconds to submit.
Is your business app costing you customers?
Tell us what's broken. We'll give you a straight answer on what it takes to stabilize — and an honest read on whether stabilization or rebuild is the right call.
