Apps your users keep.

The complete app — not just the code

Most agencies hand you an app and disappear. We ship the whole system it needs to actually run a business.

  • Smooth 60fps UI & animations
  • Offline-ready architecture

Backend & Admin Panel

Secure PHP/MySQL APIs plus an admin panel your team can actually use.

  • REST APIs with JWT auth
  • Role-based admin dashboard
  • Reports & data exports
💳

Payments Built In

Checkout, subscriptions and payouts wired in from day one — not bolted on later.

FAQ

The questions every smart client asks

Have another question? Ask us directly on WhatsApp — the founder replies personally.

It depends on screens, features and integrations — that’s why we quote fixed prices after a free call, within 24 hours. A focused starter app costs a fraction of a full marketplace; you’ll know the exact number before we start.

One codebase means roughly half the build and maintenance cost with native-level performance. Google, BMW and Alibaba use Flutter in production — and all four of our own store apps run on it.

Yes — always. An app without a backend and admin panel isn’t a product. APIs, database, admin dashboard and hosting setup are part of the delivery.

Yes. Listings, screenshots, privacy policies, permissions and review responses — we handle the entire submission until it’s approved, on your developer accounts so you own everything.

You do. 100% — code, designs, accounts and data. We hand over a clean repository with documentation.

30–60 days of included bug support depending on the package, then optional maintenance plans for updates, OS compatibility and new features. No lock-ins.

Both of our own apps added AI after launch — multilingual voice, moderation and store-safe guardrails, retrofitted without a rewrite.
