Mobile App Development
Mobile app development for iOS and Android from €3,000, delivered in 2-4 months. We develop mobile applications with React Native that work equally well on iOS and Android from a single codebase. This significantly reduces development time and cost without compromising quality. Every mobile app includes push notifications, offline mode, and integration with camera, GPS, and other device hardware features.
What You Get
- One Codebase for iOS and Android
With React Native, we develop one app that runs on both platforms, saving up to 40% of the budget compared to separate native development.
- Native Performance
Our apps are fast and responsive because they use native device components, not web views.
- Push Notifications and Engagement
Built-in push notifications for iOS and Android to keep users engaged and maintain connection with them.
- Publishing to App Store and Google Play
We handle the entire process of preparing, submitting, and getting the app approved in both stores, including screenshots and descriptions.
- Offline Mode
The app continues to work even without internet, automatically syncing data when the connection is restored.

Why Your Business Needs a Mobile App
Over 85% of internet traffic in Bulgaria comes from mobile devices. Users spend an average of 4.2 hours daily in mobile apps — more than web browsers and desktop combined. A mobile app gives your business a direct channel to the customer, without depending on Google, Facebook, or any other platform.
With push notifications, you can reach users instantly — push notification open rates are 4-8x higher than email marketing. Apps increase repeat purchases by an average of 30-40%, because they are always on the phone screen — one tap away from your product.
For restaurants, this means orders without Glovo/Foodpanda commission. For gyms — bookings and workout plans. For online stores — faster shopping and personalized recommendations. For any business with repeat customers, a mobile app is an investment that pays for itself.
React Native vs Flutter vs Native Development
There are three main approaches to mobile app development. Native development (Swift for iOS, Kotlin for Android) gives maximum performance but requires two separate teams and doubles the budget. Flutter (from Google) uses the Dart language and offers beautiful animations but has a smaller library ecosystem. React Native (from Meta) uses JavaScript/TypeScript — the most popular programming language in the world — and allows code sharing between mobile app and website.
We recommend React Native with Expo for 90% of projects. Reasons: one codebase for iOS and Android saves 40% of the budget. Expo provides OTA (over-the-air) updates — you can release a new version without App Store review, in minutes instead of days. The massive npm ecosystem means ready-made solutions for payments (Stripe), maps (Google Maps), camera, biometrics, and hundreds more features.
When do we choose something else? For games and graphics-heavy apps, we recommend Unity or Flutter. For apps requiring maximum integration with iOS-specific features (HealthKit, CarPlay) — native Swift. But for 90% of business apps, React Native is the optimal choice in terms of price/quality/speed ratio.
How Much Does a Mobile App Cost — Pricing Tiers
The cost of mobile app development depends on three factors: number of screens, backend complexity, and integrations with external services. Here are the approximate pricing tiers:
Basic app (from €3,000): 5-8 screens, user registration, profile, product/service list, push notifications. Suitable for: informational apps, simple catalogs, loyalty programs. Timeline: 4-6 weeks.
Standard app (€5,000-€10,000): 10-20 screens, user profiles with roles, online payments (Stripe, Apple Pay), API/backend integration, offline mode, admin panel. Suitable for: online stores, restaurants with ordering, fitness apps with bookings. Timeline: 6-10 weeks.
Complex app (from €10,000): 20+ screens, real-time chat, video calls, geolocation and maps, complex business logic, integration with multiple external systems, multi-language. Suitable for: marketplaces, taxi apps, health platforms, fintech. Timeline: 10-16 weeks.
All prices include: UI/UX design, frontend + backend development, testing on real devices, publishing to App Store and Google Play, and 1 month of free support after launch.

What Post-Launch Support Includes
After publishing the app, we offer monthly support plans from €200/mo that include:
Monitoring & Stability: We monitor crashes via Sentry, observe API performance and response times, and react proactively to issues — before users notice them.
New Version Compatibility: When Apple releases a new iOS or Google a new Android, we test your app and make necessary adjustments. This is critical — apps that are not updated can be removed from stores.
Bug Fixes & Minor Improvements: We fix bugs, improve UX based on user feedback, optimize performance. Up to 8 hours of work per month included in the plan.
App Store & Google Play Management: We keep the listing current — screenshots for new devices, updated descriptions, responses to user reviews.
OTA Updates: Thanks to Expo, we can push small changes (UI fixes, text, configurations) directly to users without App Store review — in minutes instead of days.
For larger new features (new module, integration with a new system), we prepare a separate quote with fixed price and timeline.

Frequently Asked Questions
Mobile app development starts from €3,000 for an app with 5-8 screens, registration, and push notifications. An average project with online payments, an admin panel, and backend integration is €5,000-€10,000. Complex apps with real-time chat, geolocation, and multiple integrations — from €10,000. All prices include UI/UX design, development for iOS and Android from a single codebase, testing on real devices, and publishing to both stores. We provide a detailed quote after a free consultation.
Both platforms from a single codebase with React Native and Expo. We write one codebase that compiles into native apps for iOS and Android. The result is indistinguishable from a native app — with access to camera, GPS, push notifications, biometrics, Apple Pay, and Google Pay. It saves about 40% of the budget and time compared to separate development for each platform.
Basic app (5-8 screens, no complex backend): 4-6 weeks. Average app with online payments and admin panel: 6-10 weeks. Complex app with real-time features, chat, and multiple integrations: 10-16 weeks. Every project starts with a Figma prototype that you approve before coding begins — so you know exactly what you will get.
We handle the entire process — from creating Apple Developer and Google Play Console accounts, through preparing screenshots and descriptions, to submitting for review and optimizing the listing (ASO). Apple review usually takes 1-3 business days, Google Play — 1-2 days. If you get a rejection, we fix and resubmit free of charge.
Yes, we work iteratively. We start with an MVP (minimum viable product) — the core features needed to launch. After launch, we collect feedback from real users and add new features based on data and priorities. This way you invest gradually and do not risk a large budget on features that may not be needed.
Yes, we have React Native and Expo experience in a product context — from taxi apps and restaurant ordering to fintech and health platforms. Our stack includes React Native + Expo for frontend, Node.js or Firebase for backend, and TypeScript everywhere for fewer bugs and easier maintenance.
Yes, push notifications are a standard feature in every app we build. We use Firebase Cloud Messaging (FCM) for Android and Apple Push Notification Service (APNs) for iOS. You can send notifications to all users, to segments (by city, interests), or to a specific user. You manage them from an admin panel or automatically on certain events — a new order, promotion, or reminder.
Maintenance from €200/mo includes: crash monitoring (Sentry), updates for new iOS and Android versions, bug fixes, minor functionality improvements (up to 8 hours/mo), and maintaining the App Store and Google Play listings. OTA updates via Expo allow small changes to be released without App Store review — in minutes. For larger new features we prepare a separate quote.
Yes, we develop the backend API as well — it is included in the price. We use Node.js with Express or NestJS, or Firebase for simpler projects. The backend includes authentication, databases (PostgreSQL or MongoDB), file storage, and API endpoints for all app features. If you already have a backend or API, we integrate the app with it.
We test on real iPhone and Android devices — not just emulators. The process includes: functional testing of every screen and flow, testing on different screen sizes, offline/online scenarios, push notifications, and payments in a sandbox environment. We release a beta via TestFlight (iOS) and Google Play Internal Testing so you can test before publishing. We also use Sentry for automatic crash monitoring in production.
