About ByteCrab

ByteCrab builds software for businesses where mistakes are very costly: patient transport, warehouses, IoT health devices.

We are based in Ukraine and have worked with clients in the US, UK, and EU for 14+ years. 150+ products shipped.

 

Areas we can help you with:

  • Mobile Development (Flutter, native iOS & Android)
  • Web Development (Laravel + Vue.js)
  • UX/UI Design
  • Team Augmentation
  • Technical Consulting
  • Long-term Maintenance & Support

What we actually do, with real examples:

A UK patient transport operator was paying thousands a month for a subscription platform too limited for how they actually work. We built them their own admin panel and Flutter tablet app instead. They own the system now, save thousands monthly, and haven't hit a feature ceiling since.

A UK logistics company ran their warehouse on outdated systems with no direct backend access. We built five interconnected Android apps around that legacy system, no rebuild required, and their teams saw a 30% productivity jump.

A German femtech startup shipped a biosensor app that started failing right before launch, no documentation, no working patch. Our developer rebuilt the device sync from scratch and got them from an 85% to a 96% bug-free rate in three months.

Stack: Flutter, native iOS/Android, Laravel, Vue.js. If your team is drowning in spreadsheets, paper forms, or a platform you have outgrown, that is exactly the kind of mess we are good at.

We work two ways. If you've already got a team and just need more hands, we plug a developer straight into it; they join your stand-ups, use your tools, and report to your PM. If you don't have a team, or don't want to run one, we take the whole project end to end: scope it, build it, ship it, keep it running after. You pick which one fits; we're not going to push you into a bigger engagement than you actually need.

Vital signs tracking app

Vital signs tracking app

Their goals: Provide continuous, accurate vital sign tracking to improve care efficiency and reduce human error Give clinicians remote access to patients in hospitals and at home Offer predictive analytics to spot health risks early and support proactive medical decisions Keep the platform simple and intuitive for both patients and healthcare providers How It Works: Medical personnel get registered accounts linked to their clinic, and administrators create patient accounts and assign physical devices. A wearable device with LTE connectivity captures the patient's vital signs and syncs them to the patient's account. Authorized clinicians see health data in real time in the app, and patients see their own results. Alerts notify both patients and clinicians about critical readings, and thresholds can be customized per patient. Key Features: Wide Range of Metrics: Pulse, respiratory rate, oxygen saturation, temperature and blood pressure, plus device management with battery warnings and replacement Real-Time Data Transmission: The LTE wearable sends data to the mobile app instantly, for both healthcare professionals and patients Predictive Analytics: Built-in algorithms analyze vital sign trends and warn users about potential health risks Customizable Alerts and Settings: Doctors and patients control how results are delivered and set individual thresholds Privacy and Data Control: Full control over data and privacy settings Cross-Platform Automated Testing: iOS and Android consistency, real-world scenario coverage including data syncing, and performance validation under high user loads Outcome: A cross-platform mobile app and progressive web app that gave the client real-time, remote vital sign monitoring for hospital and home care. Automated testing reduced debugging time, improved app stability and supported compliance with healthcare standards. The project ran for 12 months (2023-2024). Tech Stack: Flutter (iOS and Android), Progressive Web App.

Allergy Health App

Their goals: Launch a working iOS and Android app within four months Build a scalable food database with comprehensive ingredient information Use a privacy-first architecture that stores no personal data on servers Support subscriptions without collecting emails, phone numbers or logins How It Works: A user creates a profile with their specific intolerances, allergens and dietary preferences. The user scans or searches for a food product, and the app cross-references its ingredients with the profile and flags problem items. The user can follow a meal plan, track symptoms and adjust the profile as needs change. Account features run on a locally generated ID stored only on the device, so no personal data ever reaches a server. Key Features: Food Classification: Scan or search products to instantly see whether they contain ingredients the user is intolerant to Custom Intolerance Profiles: Detailed, editable profiles covering intolerances, allergens and dietary preferences Scalable Food Database: Calories and ingredient data in a structure that is easy to access and change Privacy-First Accounts: Locally generated device ID instead of emails, phone numbers or logins Demo Version: Users can try the app before buying Native iOS and Android: Built natively for speed and reliability Outcome: The app launched on schedule within the 4-month timeline, runs fast and reliably on both iOS and Android, and met the client's goals. With ongoing support it gained popularity and now serves a large global audience. Tech Stack: Native iOS and Android, custom scalable food database, locally generated device IDs.

Rebuilding a Quran app for iOS and Android

Rebuilding a Quran app for iOS and Android

Their goals: Redesign the interface into a calmer, clearer experience built around reading rather than browsing Run smoothly on a wide range of devices, including older and low-end hardware Deliver full feature parity between Android and iOS Boost engagement with location-based prayer times, customizable notifications and home screen widgets Enable offline access to text and audio in multiple languages How It Works: A code review of the existing app showed a weak structural foundation, and the client decided to rebuild instead of patching. Users browse numbered lists of every surah and juz', with search and bookmarks. They listen to recitation in Arabic and English, separately or together, with a choice of nine Arabic voices. Text and audio are stored offline, so the app works without a connection. Prayer times, notifications, widgets and the Qibla direction adapt to the user's current location. Key Features: Surahs and Juz' Lists: Individually numbered lists with search and bookmark management Audio Listening: Arabic and English read aloud, separately or together, with nine Arabic reciters Offline Access: Text and audio in multiple languages stored locally, while keeping the app small enough for modest devices Qibla on the Map: Prayer direction from the user's location, shown as a map with distance or as a compass Prayer Tools: Automatic daily prayer times, customizable notifications and home screen widgets Native iOS and Android: Full feature parity, stability and usability on both platforms Outcome: The crash-prone legacy app became a modern cross-platform product that now serves more than two million users. Both platforms match each other in stability and usability, and new capabilities such as audio recitation, search, offline saving, Qibla mapping and widgets were added. The architecture is deliberately streamlined for whoever maintains it next. The project took 4 months (2020-2021). Tech Stack: Native iOS and Android.
