Why apps fail
Downloads are easy. Retention is the job.
Most apps lose most of their users within weeks. The cause is rarely the code: it is confusing onboarding, slow screens and features nobody asked for.
We start with the core job your users need done, design it around real devices and networks, and measure retention from the first release.
- UX first: tested flows before a line of code
- Fast and stable: crash-free sessions and quick start-up
- Full stack: app, API, database and admin panel
- Launch support: store listings, review and analytics

Buyer guide
App development cost, explained honestly.
How much does an app cost?
Realistic app development cost ranges: a focused MVP for one platform or cross-platform is $15,000 to $40,000; a full consumer or marketplace app with a back end and admin panel is $40,000 to $120,000; complex apps with real-time features, maps or heavy integrations cost more. Starting prices with us begin at $2,000 for small utility apps.
Flutter vs React Native vs native
Flutter and React Native both ship to iOS and Android from one codebase and suit most business apps. Pick Flutter for highly custom UI and smooth animation, React Native if your team already uses React, and native Swift or Kotlin for hardware-heavy or graphics-heavy apps.
How long does it take?
Ten to twenty weeks for most first releases, including design, build, testing and store review. Simple internal apps can ship faster.
Starting price: $2,000 (about AED 7,340) for clients outside India. Every project then gets a written, itemized quote. See all starting prices.

How much does it cost to build an app with Monocerix?
Small apps start from $2,000 for clients outside India. Most business apps fall between $15,000 and $60,000. You get an itemized quote after a scoping call.
Should I build for iOS or Android first?
In the US, UK and GCC, iOS often carries more paying users, so many clients start there or go cross-platform. We will look at your audience before recommending.
Do you publish the app to the App Store and Google Play?
Yes. We prepare listings, privacy labels and builds, and handle review feedback until the app is live.
Can you build Arabic apps?
Yes. We design right-to-left layouts properly, including icons, navigation and mixed Arabic-English text.
Do you maintain apps after launch?
Yes. Maintenance plans cover OS updates, bug fixes, monitoring and new features.
Who owns the app and code?
You do: the code, designs, store accounts and data.
