We don't build those.
We engineer mobile applications for production. Native performance, offline-first, multilingual by default. iOS, Android, Flutter, React Native — under one team, end-to-end.
How we ship mobile.
Five platforms. One engineering team.
We pick the platform that fits your problem — not the one we know best. Native when the OS matters, cross-platform when budget and speed do.
Native iOS
Swift · SwiftUI · CombineNative iOS development for products where iOS-first quality matters. SwiftUI interfaces, Combine reactivity, deep platform integration (Live Activities, Widgets, App Intents).
iOS-first products, premium consumer apps, enterprise iPad rollouts.
Native Android
Kotlin · Jetpack Compose · CoroutinesNative Android with Kotlin and Jetpack Compose. Material 3 design, deep OS integration, optimized for low-end devices common in MENA and Africa.
Android-first markets, low-end device targets, deep OS features.
Flutter
Dart · Flutter · RiverpodSingle Dart codebase shipping iOS and Android with native performance. Fast iteration, consistent UI across platforms, mature for production.
Cross-platform from day one, budget-conscious teams, design-heavy apps.
React Native
TypeScript · React Native · HermesReact Native with TypeScript for teams already shipping React on the web. Native modules where needed, JS bridges everywhere else.
Web-first teams adding mobile, content-driven apps, internal tools.
Embedded mobile
Custom builds · Hardware-awareMobile applications bound to specific hardware or operating environments — kiosks, POS terminals, industrial tablets, vehicle systems. Offline-first, hardware-aware, multi-day uptime.
Kiosks, POS, industrial tablets, fleet vehicles, hardware-bound apps.
What makes a mobile app survive.
Six non-negotiables. Every Symloop mobile app ships with all six. None of them are optional.
Tested on real devices, not just simulators.
Offline-first — works where signal doesn't.
Multilingual from day one (Arabic RTL, French, English).
Crash-free target above 99.5%, monitored from day one.
Performance budget enforced in CI (no >2.5s first-paint).
Accessibility built in (VoiceOver, TalkBack, large text).
Four phases. Discovery to store.
Discovery
Sit with your team, understand the user, audit the data, identify the right platform (or honestly tell you cross-platform is wrong here), scope a paid pilot.
Design system
Build the interface design system: components, tokens, accessibility patterns, RTL support. Tested on real devices before a line of production code.
Engineering
Production code with CI, unit + UI + integration tests, crash monitoring, performance budgets, real-device test farm, beta releases via TestFlight and Play Console.
Ship & operate
App Store + Play Store submission, staged rollouts, crash triage, performance monitoring, OS update reviews, store optimization. Long-term mobile partner.
Numbers we engineer toward.
Every Symloop mobile app is measured against these. Not vanity metrics — operational ones.
Every render under the 16ms frame budget. Tested on cheap Android devices, not flagship iPhones.
Time-to-interactive under 2.5 seconds on a mid-range Android with a 4G connection.
Sentry-monitored from day one. Every regression triaged before the next release.
Unit + UI + integration tests. Every critical path covered before merge.
When using Flutter or React Native, one codebase for iOS and Android with shared logic and platform-specific UI where needed.
App Store + Play Store + regional variants (App Store Connect supports 175 countries; we ship to the relevant 9 by default).
Per-platform stacks. All production-grade.

Common questions.
How much does a mobile app cost?
Mobile app pricing depends on platform count, complexity, and integration depth. A focused single-platform pilot starts at €25K. A full cross-platform app (iOS + Android) typically lands between €60K and €200K. We start with a fixed-price discovery (1–2 weeks) followed by a fixed-price pilot before committing to a full build. The discovery delivers a transparent quote — no estimate-by-vibes.
How long does a mobile app take?
A pilot delivers a working app in 6–10 weeks. A full production app reaches the App Store / Play Store in 16–24 weeks for cross-platform, or 20–28 weeks for native iOS + native Android in parallel. Embedded and hardware-bound apps vary depending on hardware integration scope.
Should we go native or cross-platform?
It depends. Go native (iOS + Android separately) when platform-specific OS features matter, when your audience is heavily skewed to one platform, or when the app must feel premium. Go cross-platform (Flutter, React Native) when speed, budget, and consistency matter more than platform-specific polish. We help you decide in discovery — and we'll tell you honestly if cross-platform is the wrong call for your case.
Do you build offline-first apps?
Yes — it's a default, not a feature. Every Symloop mobile app is designed to work without an internet connection: local-first storage, queued mutations, sync on reconnect, conflict resolution. This is non-negotiable in markets where signal is unreliable.
Do you handle App Store and Play Store submission?
Yes. We handle the full submission process: store listings, metadata, screenshots, app review responses, staged rollouts, hotfix deployment. We've shipped apps to both stores in 9+ regional markets. If you don't have store accounts yet, we help you set them up.
Do you maintain apps after launch?
Yes. We offer ongoing operations contracts: crash triage, performance monitoring, OS-update compatibility (iOS major releases, Android API targets), feature work, security patches. Or we can hand off cleanly to your internal team with documentation and a knowledge transfer.
