Mobile app development for apps people actually open

The cost of a custom mobile app depends on scope, the number of platforms (iOS, Android, or both), feature complexity, and what the backend needs to do. A focused MVP with a tight feature set costs much less than a full consumer app or an enterprise tool with many integrations. Most of our projects run on fixed-price terms. It starts with a free 30-minute call, then a short discovery phase where we define the features and screens. After that, we send a milestone-based proposal with a fixed price, so you have full clarity on cost and timing before any work begins. No surprise invoices halfway through.

A focused MVP typically takes 10 to 16 weeks from kickoff to App Store submission. Larger apps with many user roles, integrations, or offline features take longer, and we give you a clear estimate once the scope is defined. We front-load design and prototyping in the first two weeks, so you can tap through the app before engineering starts, and the sprints that follow stay on budget. During discovery, you get a detailed milestone plan with fixed dates, not a vague range. You also see progress in weekly demos throughout the project, so there are no surprises at the end.

For most products, cross-platform app development with Flutter or React Native is the right call. You get one codebase for iOS and Android, faster updates, easier maintenance, and a large pool of developers for the future. Native iOS app development in Swift, or Android app development in Kotlin, makes sense when you need deep platform features, such as ARKit, HealthKit, custom hardware, or widget-level OS features. Performance is rarely the deciding factor today, since modern cross-platform apps feel native for most use cases. We give you a direct recommendation in the first discovery session, based on your product goals and the team that will own the app after launch.

Yes. Our launch package covers App Store and Google Play submission from start to finish: App Store Optimization, metadata, screenshots, review submission, and a phased rollout, so issues can be caught with a small group of users first. Both stores have their own review rules, and rejections usually come from small details like privacy labels, login requirements, or payment rules. We handle those details so your launch date does not slip. We also set up crash monitoring and analytics dashboards before release, so you have full visibility into how the app performs and how people use it from day one.

Mobile apps need regular care. Apple and Google ship major OS updates every year, and an app that no one maintains will start breaking within months. That is why most of our mobile clients move to a monthly retainer after launch. It covers maintenance, OS compatibility updates, new features, performance fixes, and A/B testing, so you can improve the app based on real usage data. We also watch crash reports and store reviews, so problems are fixed before they turn into bad ratings. Most of our mobile clients stay on a retainer for at least the first year after launch.

Yes. Rebuilds are a big part of our mobile app development work. We start with a technical audit of your current app, covering performance issues, outdated libraries, security gaps, and architecture problems. Then we plan a migration path that keeps the existing app live while the new version is built, so your users are never left without a working app. We can move a legacy native codebase to Flutter or React Native, upgrade an older Ionic or Cordova build to modern standards, or restructure code your team can no longer maintain. You get a clear recommendation on whether to refactor or rebuild before any major work starts.

Creiden is a mobile app development company with 15+ years of experience, 400+ projects, and clients in 15+ countries. Our team has shipped apps to both the App Store and Google Play across consumer, enterprise, and e-learning products, using Flutter, React Native, and native code. We plan crash monitoring, App Store Optimization, and post-launch performance from the first sprint, not as an afterthought. One example is Hindam, an on-demand laundry app we built for the Saudi market, with real-time order tracking and a simple scheduling flow for iOS and Android. Most clients stay with us after launch, because a good app keeps improving long after release.
