Ziroop came to us with a vision: connect partygoers through shared music experiences. We built their MVP — a mobile-first platform with event-based audio streaming, user matchmaking, and admin tools. Fast to market, easy to scale, ready for feedback from real users.
We built a tablet app and admin panel for the UK’s top patient transport service — helping their teams log every trip, monitor real-time status, and export reports without the usual paper mess. Works offline, updates live, and keeps the whole process tight from dispatch to drop-off.
A German femtech startup asked us to step in when their app stopped syncing with a biosensor device. We fixed the issue fast, kept their brand features intact, and added content delivery and retry logic — helping them retain users and avoid further disruption.
We helped a Japanese logistics company improve delivery flow with a custom mobile app for drivers. Built with offline maps, smart routing, and live chat — so they can manage orders, scan IDs, and stay connected even when the signal drops.
Working with Bytecrab has been a great pleasure. They are very competent and responsible.
They keep their estimate which are very precise because they have so much experience with development of apps. I can only recommend them to other companies.

Starting from the design team all the way through delivery, the Bytecrab team is responsive and delivers quality results.
Co-Founder at NReach Inc
For an advertising/web business, the site was not mobile responsive. We hired Bytecrab to re-structure the front-end, so it responds well to mobile and tablets. They did a great job in that effort, retaining the design, and adjusting to our requirements. Their work included a design phase where we could see how the site would look in mobile.

Member of the Advisory Board at enautics
From 10 candidates on my project, my choice was the Bytecrab team. I have never met such attitude and pro-level of competence before. As a matter of fact, I`ve got several fresh ideas in terms by CEO himself while we discussed project development, business value, and its strategy, Really inspired by such an approach cause that`s really rarity nowadays from thousand of developers.
Thx again guys. Hope to work with you again.
Cofounder at IT Delight
I've worked with the Bytecrab for about a year. They've built a web and mobile (iOS & Android) application for our company and the experience has been fantastic. The entire team is dedicated, hard working, and has deep technical knowledge. We ve been assigned a project manager who ensures everything is completed on time and on budget - they are all an absolute pleasure to work with. I look forward to working with them in months to come. I highly recommend their work!

The days of writing different code for Android and iOS are over. Flutter’s reusable code lets you create only one code base and leverage it not only for Android and iOS mobile devices but also for the web, desktops, and beyond. This significantly shortens development time, decreases costs, and allows you to launch your app much sooner.
Flutter isn’t just about writing once for two platforms. It’s about moving faster, scaling smarter, and solving complex product challenges with clean architecture and beautiful UI. Here’s how we’ve used Flutter to make a difference:
We stabilized unreliable Bluetooth syncing between biosensors and the mobile app, increasing the app’s reliability and improving the daily experience for 10,000+ users.
In an eCommerce project with multiple roles (admin, picker, driver), we delivered consistent cross-platform experiences — all from one Flutter codebase.
For a public transport client, we used Flutter and native integrations to read NFC cards offline — critical for stations without stable internet.
We created a modular Flutter base that powers three white-label apps, helping a health brand expand its offerings without rebuilding the core logic.
In an art-related membership platform, we used Flutter to match premium design requirements without sacrificing performance on low-end phones.
With Flutter + WebSockets, we delivered a smooth, room-based music experience where users join events, chat, and sync audio in real time.

Flutter lets you build apps for iOS and Android using a single codebase, which significantly reduces development time and cost — without compromising performance or design flexibility.
Yes. Flutter uses its own high-performance rendering engine, allowing full control over every pixel. Apps built with Flutter run smoothly and feel truly native on both platforms.
Absolutely. Flutter supports native integrations through platform channels, so we can connect it with device-specific features like NFC, Bluetooth, sensors, and more — just like in native apps.
Yes. We use scalable architecture, modular code, and robust state management tools (like BLoC or Riverpod) to ensure your app is ready to grow — whether it serves hundreds or millions of users.
It depends on the project scope. A basic MVP can be done in 4–6 weeks. More complex apps usually take 2–4 months. After our Discovery Phase, we provide a detailed estimate with clear milestones.
Definitely. We build Flutter apps with maintainability in mind — clean code, clear documentation, and reusable components make future updates fast, safe, and cost-efficient.
