Mobile Apps That Users Actually Keep
Most apps get uninstalled within the first week. The ones that stick are fast, focused, and solve a specific problem without friction. CimpleO builds cross-platform mobile applications for iOS and Android — consumer apps, enterprise tools, and IoT-connected field apps — using React Native and Flutter so you get one codebase that performs like native on both platforms.
Cross-Platform App Development
One codebase, two platforms, native feel. We build with React Native and Flutter — both proven at scale in production apps used by millions — so you don’t pay to maintain separate iOS and Android codebases. Performance is on par with native for the vast majority of use cases, and iteration speed is far faster.
Consumer Apps
We design and build consumer-facing apps with onboarding flows that convert, UX patterns that reduce support tickets, and push notification strategies that drive retention. From marketplace apps and content platforms to health trackers and booking tools, we’ve shipped consumer products across categories.
Enterprise & Field Apps
When your field teams need a reliable tool that works on intermittent connections, we build offline-first mobile apps with background sync, barcode scanning, digital signatures, and integration with your back-office systems. We build for warehouse floors, construction sites, and remote locations — not just office Wi-Fi.
IoT-Connected Mobile Apps
We pair mobile apps with hardware — Bluetooth sensors, GPS trackers, smart meters, and custom IoT devices. Your mobile app becomes the control interface and data viewer for connected equipment. Designed for field engineers and operations teams who need real-time device data and remote control in their pocket.
Why Teams Choose CimpleO for Mobile
- Design included — UX/UI design is part of the engagement, not a separate agency
- Cross-platform by default — React Native or Flutter, never two separate native codebases unless truly required
- App Store delivery — we handle TestFlight, App Store, and Google Play submission and review cycles
- Post-launch support — OS updates, crash monitoring, and feature iterations without starting over

Frequently Asked Questions
React Native or Flutter — which should we choose?
For most product companies: React Native if your team has JavaScript/TypeScript expertise and you need a large ecosystem of libraries; Flutter if you want pixel-perfect custom UI and your team is open to Dart. Both are production-proven at scale. We'll recommend based on your specific requirements — we build with both and have no vendor bias.
How much does mobile app development cost?
A well-scoped MVP mobile app (core features, two platforms, app store submission): $30,000–$70,000. A production-grade consumer app with backend, admin panel, and integrations: $80,000–$200,000+. Timeline: 3–5 months for MVP, 6–12 months for full product. We scope in detail before quoting.
Do you include design, or just development?
Design is part of every engagement. UX/UI design is included — we don't outsource it or hand you a component library and tell you to figure it out. You get Figma screens and an interactive prototype before development starts.
How do you handle App Store and Google Play submission?
Fully. We handle provisioning profiles, signing certificates, App Store Connect setup, Google Play Console, review guidelines compliance, and the submission process. If an app gets rejected, we handle the response and resubmission.
Can you build on top of an existing mobile codebase?
Yes. We've joined existing React Native and Flutter projects, audited code quality, resolved technical debt, and taken over feature development. Send us the repo and we'll assess it honestly before committing.
Do you offer post-launch maintenance?
Yes — OS updates, crash monitoring (Sentry), performance regression fixes, and feature iterations. Most clients keep us on a retainer after launch. Mobile platforms update twice a year and apps need active maintenance to stay store-compliant and performant.
