Key details about this service to help you decide. Generated by Zinn Hub, not the seller.

Platform Coverage

Android & iOS (Cross-Platform)
Built with Flutter, meaning a single codebase delivers native-quality apps on both Android and iOS — reducing cost and development time compared to building two separate apps.

Delivery & Scope

3–4 Screens in 7 Days
The base package covers a small-sized app with 3–4 screens including design, app icon, splash screen, and submission to both the App Store and Play Store within 7 days.

What's Included

Source Code + Ad Integration
Every tier includes full source code ownership and ad network integration out of the box — plus app submission support, so buyers don't need to manage store deployment themselves.

AI & Backend Ready

Firebase, REST API & AI Features
Beyond standard app builds, the provider offers AI-powered features (chat, automation), Firebase backend, and third-party API integrations — suitable for startups needing more than a basic app.

The app came out exactly as I imagined, simple, calming, and easy to use. The seller nailed the outdoorsy feel with the color palette, and the layout is clean and intuitive. Looking forward to seeing how it expands in the future!

The Flutter app for my local farmers market, developed by Mahamudul, connects vendors directly with customers. It features real-time inventory updates and a seamless pickup scheduling system that has streamlined operations for everyone involved.

Great experience overall. The task was done smoothly, the code was clean, and communication was clear. Would definitely work again

In every aspect, this mobile app surpassed my expectations. The user interface feels contemporary and straightforward, and the booking and notification tools operate without a hitch. The job was completed on schedule, and there was excellent communication. I'm comfortable telling people about this mobile app service.

Amazing work! The seller delivered a beautifully designed and fully functional habit tracker screen. The habit list, add new habit, and mark as complete features work perfectly, and the clean, colorful, and mobile-friendly design makes the app a joy to use.

I’m very impressed by Md. Selim and his Flutter development skills. He worked efficiently and delivered everything ahead of time. The app he built is clean, responsive, and user-friendly. A reliable and talented developer indeed.

Mahmud’s team operates with integrity, skill, and genuine dedication to excellence. If you’re looking for a partner who truly understands quality, look no further than Mahmud and his incredible team. Highly recommended!

Great communication and a very clear plan for LogoSnap from the start. The app scope stayed lightweight and beginner-friendly, with smart features like login + saved designs without adding unnecessary clutter. Loved the modern minimal style direction with light tones and soft gradients. Fair pricing, realistic timeline, and the whole process felt organized.

This was one of my best Zinn Hub experiences so far. He took my idea, refined it, and delivered a polished mobile app that runs flawlessly. Communication was smooth, and his technical skills truly showed in every detail. The Task Details Screen was implemented perfectly and strongly recommended.

The Grocery List App you developed is a masterclass in minimalist, focused design and flawless functionality. The single-screen approach is brilliantly intuitive, eliminating any complexity and allowing users to manage their lists with immediate ease. Highly recommended seller.

Neilul and his team once again proved why they are one of the best in mobile app development. They redesigned my booking calendar beautifully, making the flow faster and more user-friendly. The new technician arrival alerts with push notifications work perfectly and add real value. I also loved the updated dashboard UI, modern, clean, and much easier to navigate. The new service-history module keeps everything organized and helps track recent bookings effortlessly. They boosted overall app performance and polished the UI for a smoother experience. All minor bugs were fixed carefully, and the app now runs better than ever.

Keramot built a Flutter app for my e-commerce store, integrating multiple payment gateways and a complex product catalog. The app is fast, reliable, and has significantly boosted our mobile sales. He is a highly skilled and reliable developer.

The core functionality for logging daily moods is incredibly smooth, and the ability to view previous entries in both a list and a clean calendar view is implemented perfectly. The option to edit or delete past entries adds a crucial layer of user control. Most impressively, the clean and minimal interface makes the entire experience frictionless and pleasant to use daily.

Outstanding experience from start to finish! He understood the problem immediately, fixed it quickly, and explained things in a way I could actually understand. The app now works perfectly without any confusion or extra effort from my side. Communication was smooth, delivery was fast, and the result was exactly what I needed. I would 100% work with him again and highly recommend him to anyone

Great work creating the publishing tools screen and adding compose/arrange blog features with a clear posting plan. Clean implementation, fast delivery, and excellent communication. Highly recommended.
