## How the Beyut Libya app got to 10,000 downloads

Rashid Kadura first hired us for one job: add a payment gateway to Beyut Libya, his property marketplace. Several teams had worked on it before us, and the website and the app were not properly connected to the API. We rebuilt the web platform first. Then he asked us to look at the mobile app.

It had the same problems as the web code, and patching it would have cost more than starting clean. So we rebuilt it in Flutter with Firebase: push notifications, messaging between buyers and agents, map search, and in-app purchases, which is how the marketplace earns. Sellers buy yearly listing slots through Google Play or the App Store, and each slot publishes one property.

The app, بيوت ليبيا, is live on both stores and has passed 10,000 Android downloads. Rashid is based in Saudi Arabia and kept coming back with the next job, which is the review we care about most.

## Flutter or React Native?

We build in both, and the written plan recommends one for your app and your team, not out of habit.

| Question | Flutter | React Native |
| --- | --- | --- |
| Same look on iOS and Android | Yes. Flutter draws its own widgets | Uses native components, so small differences show |
| Language | Dart, quick to pick up | JavaScript or TypeScript, shared with a React website |
| Custom UI and animation | A strong fit | Good, sometimes needs native modules |
| Sharing code with a web app | Possible, less common | Easier alongside React and Next.js |

## Taking over a Flutter app someone else built

Most apps that reach us were started by another team. This is the order we work in.

- **Get the keys first.** Google Play Console, App Store Connect, the signing keys, the Firebase project and the source repository. Without them, no update can ship.
- **Read before writing.** A written audit of the app, the API and the server, walked through on a call, as we did for Beyut Libya.
- **Stabilise, then add.** Crashes, broken API calls and failed payments come before any new feature.
- **Ship under the same listing.** Users update the app they already have, so ratings, reviews and downloads stay.

## What a Flutter app costs

Typical ranges from our cost estimator, including the backend and admin panel.

| Build | Typical range | Timeline |
| --- | --- | --- |
| Mobile App | $13,000 to $21,000 | 6 to 9 weeks |
| Marketplace App | $19,500 to $31,500 | 8 to 11 weeks |

Taking over an existing app starts with a written audit, so you know what you are dealing with before anyone quotes a rebuild.

## Built and running

- [Beyut Libya: Real Estate Marketplace Rescue](https://eaquirstech.com/en/work/beyut-libya-real-estate-platform): A Libyan real estate marketplace several vendors left broken. We rebuilt the web platform and Flutter app without losing a listing, and added local payments. Result: 0 listings lost in the rebuild.

## FAQ

### How much does a Flutter app cost?

A typical mobile app with its backend and admin panel is $13,000 to $21,000, and a two-sided marketplace app $19,500 to $31,500. The written plan gives the exact figure.

### Can you take over our existing Flutter app?

Yes. We start with a written audit and access to the store accounts and code, stabilise what is there, then decide with you whether to fix or rebuild. Beyut Libya's app was rebuilt; many apps only need fixing.

### Do you publish to the App Store and Google Play?

Yes. We handle the store listings, review feedback and release pipeline, including in-app purchases through Google Play and App Store billing.

### Will the app work in Arabic?

Yes. Beyut Libya's app is Arabic first, right to left, with English alongside.

### Flutter or React Native, which should we pick?

Flutter when you want one identical interface on iOS and Android and a lot of custom UI. React Native when your team already works in React and you want to share code with a website. We recommend one in the written plan.
