Stripe payments work in dev, break in production
Apple rejected our build — for the third time
The Cursor-built app crashes on cold start
Our PM prototyped with AI — now it needs to ship to real users
We hired a vibe coder and inherited code that won't compile
Claude Code wrote it, but the production build fails
Customers, investors, or pilots are waiting — and we're stuck
You're not alone. We've seen all of these. We fix them.
Free audit. Fixed price. Shipped by the date — guaranteed.
Three promises, in plain English. The audit is the gate — we only quote rescues we're confident we can ship.
A free 30-minute code audit
A senior engineer pulls your repo, identifies the blockers, and tells you honestly if we can fix them. No commitment, no pitch.
A fixed-price quote
One number, one date. No hourly billing surprises. Typical rescue: $2k–$5k. You sign before we touch a keyboard.
Shipped by the date — guaranteed
We deliver by the date in your Statement of Work. If we miss it, we keep building at no extra cost until your app is accepted.
The blockers we fix every week.
Push notifications (FCM / APNs)
Stripe / RevenueCat / Apple IAP

How the guarantee actually works.
The guarantee depends on which tier we agree on after your audit. We tell you upfront — no buried small print.
$3,000–$4,500 rescues
30-day ship guarantee
- The free audit costs you nothing and commits you to nothing.
- After the audit, we send a written SOW: scope, fixed price, hard delivery date.
- If you sign: 50% upfront. We start.
- We ship by the date in the SOW — that's the deal.
- If we miss the date:we keep building at no additional cost until your app meets the agreed acceptance criteria. The remaining 50% doesn't trigger until acceptance.
- You keep all code regardless.
$1,500 single fix sprint
Fix it or refund
- The free audit costs you nothing and commits you to nothing.
- After the audit, we name the single blocker we'll fix — e.g. "production push notifications working on iOS and Android."
- You pay 100% upfront (smaller engagement, simpler billing).
- If we don't fix it within 14 calendar days:full refund.
- No App Store submission at this tier — that's the rescue tier above.
We can offer real guarantees because we only take on rescues we're confident in after seeing the repo. The audit is the gate — both ways.
The 30-day path.
Day 0 — Book the audit
Share your repo + a short description of what's stuck. We schedule the 30-min call.
Day 1–2 — Audit call
Senior engineer reviews your repo live. You leave with scope, price, and delivery date in writing.
Day 3–25 — We build
Daily Slack / Discord updates. You see commits as they land — no slide decks, no excuses.
Day 26–30 — Ship
TestFlight + Play Internal Testing → App Store submission → first review pass.
One audit. Four tiers. You decide.
We quote your tier after the free audit so you know exactly what you're getting and what the guarantee is — before any payment. Solo founder, product team, or funded SMB: the audit's free either way.

Who this is for — and who it's not.
This is for you if
- check_circleYou (or your team) have a working prototype built with Lovable, Bolt, Cursor, Claude Code, FlutterFlow, base44, or similar
- check_circleYou're a solo founder, product team, non-technical co-founder, agency, or SMB stuck on the production wall
- check_circleYou know what's blocking you — or you don't, and you'll show us the repo
- check_circleCustomers, pilot users, investors, or your own roadmap are waiting
- check_circleYour budget is at least $1,500
This is NOT for you if
- closeYou don't have a built prototype yet — start with our startup MVP service (built from scratch, from $8k)
- closeYou want us to add 10 new features (this is rescue + ship, not new development)
- closeYou can't share your repo (we audit code, not screenshots)
- closeYour budget is under $1,500 (try a freelancer or stay in your current tool)
- closeYour app is already shipped to the App Store and broken — use our App Stabilization service instead (larger codebases, $8k+)
A senior Flutter team. No agencies, no juniors, no hand-offs.
AppsVanta has shipped 20+ production apps for clients across the US, Canada, and EU since 2022. We work US Eastern business hours. We don't outsource. The same engineer who joins your audit call writes the code, ships the commits, and submits to the App Store.
Tell us what's stuck.
A senior engineer replies within 4 business hours with a calendar link. We review the repo only to prepare for the audit — never shared, never trained on, never opened without you on the call.
Frequently Asked Questions
Most are. That's normal — we've seen prototypes from Lovable, Bolt, Cursor, Claude Code, FlutterFlow and base44 in every state imaginable. The free audit is exactly where we tell you whether it's salvageable in budget, needs a partial rebuild, or should be started fresh.
We primarily rescue Flutter, React Native, and Capacitor apps. We can also convert Lovable / Bolt / Cursor web prototypes into native Flutter apps for iOS and Android — that's a separate, larger scope quoted on the audit call.
Yes. Mutual NDA before the audit if you want one — send yours, or we'll send ours. We use your repo only to prepare for the audit. We never share it, never train on it, and never look without you on the call.
Scope changes restart the clock on a new SOW with a new price and a new delivery date. The 30-day ship guarantee covers the originally agreed scope only — that's how we can offer it without going broke.
We tell you honestly and walk away. No charge. We may quote you a larger rebuild ($12k+ for a full Lovable-to-Flutter conversion, for example), but you're free to take that quote elsewhere — your code, your call.
AppsVanta is a senior team that operates in US Eastern business hours for client calls. Engineering happens around the clock. The engineer who joins your audit is the engineer who writes the code — no hand-offs to juniors or outsourcing.
You. Always. We don't keep any rights, license, or claim to the code or the App Store listing. Everything ships to your accounts, in your name.
Stripe (card), ACH transfer, and international wire. The Single Fix Sprint is 100% upfront. The Full Rescue tiers are 50% upfront and 50% on delivery — that second 50% is what triggers (and motivates) the on-time guarantee.
