iOS & Android Apps Built for Startup Scale
We don't just build apps; we build businesses. From high-fidelity design to App Store deployment, we use React Native and Flutter to ship faster and smarter.
React Native, Flutter, or Native? The Honest Answer
Founders arrive at this question expecting a religious debate. The practical answer is simpler than the internet makes it: for almost every startup, cross-platform wins. One codebase means one team, one bug to fix instead of two, and both stores launched on the same day for roughly 60% of the cost of building native twice. React Native and Flutter both deliver near-native performance for the app types most startups build — marketplaces, social products, booking tools, fintech dashboards.
When does native still make sense? Heavy 3D graphics or gaming, deep hardware work (custom camera pipelines, advanced Bluetooth), or apps where a platform-specific feature is the product itself. If that's you, we'll say so in the first call — building cross-platform first and rewriting later is far more expensive than choosing right up front.
What actually drives your app's cost isn't the framework — it's user roles (a customer app plus a driver app plus an admin panel is three products), real-time features (chat, live tracking, notifications), and integrations (payments, maps, identity verification). This is why our quotes itemize by feature, so you can trim scope and see exactly what each cut saves.

Ordering flows, real-time order tracking, and driver apps with route optimization.
Travel & Hospitality
Booking engines, itineraries, offline maps, and multi-currency payments.
Logistics & Field Work
Offline-first data capture, barcode scanning, and fleet coordination for teams in the field.
Apps & Platforms We've Delivered
From native Android to cross-platform builds — real apps in real users' hands.
Freelancer vs Big Agency vs Aciezen
Mobile apps are long-term commitments — the wrong build partner costs you twice. Here's the honest comparison.
| Freelancer | Big Agency | Aciezen | |
|---|---|---|---|
| Team coverage | One person for design, code, QA | Full teams, full price | Senior cross-platform team, startup-sized |
| Cost | $5–15K, quality lottery | $60K+ minimum engagements | $15–40K fixed-quote MVPs |
| Cross-platform strategy | Whatever they happen to know | Sometimes two native teams billed twice | One React Native/Flutter codebase for both stores |
| Store submission | Often your problem | Handled, eventually | Handled end-to-end, rejections included |
| Code ownership | Accounts often in their name | Yours, per contract | Your accounts, your code, from day one |
| After launch | Gone by the first iOS update | Premium maintenance contracts | Flexible plans that keep the app alive and updated |

Mobile App Development FAQ
Should I build a hybrid or native mobile app?+
For 95% of startups, hybrid frameworks like React Native or Flutter are the best choice. They allow you to build one codebase for both iOS and Android, drastically reducing development costs and time-to-market without sacrificing performance.
How much does a mobile app MVP cost?+
A professional mobile app MVP typically ranges from $15,000 to $40,000 depending on features like user authentication, payment processing, and complex API integrations.
How long does it take to build a mobile app?+
A standard mobile MVP takes 3–5 months from design to App Store submission. We follow an agile process with weekly demos to ensure the product matches your vision.
Do you handle App Store and Google Play submission?+
Yes, end to end. We prepare the store listings, screenshots, and privacy declarations, handle Apple's review process (including the rejections that surprise first-time founders), and manage the release rollout on both stores.
Do I own the app and its source code?+
Fully. The developer accounts are registered in your name, and the complete source code, design files, and backend infrastructure are handed over with documentation. You can continue with us, hire in-house, or switch teams at any time.
Will my app work offline?+
If your users need it, yes. We build offline-first data syncing for apps used in the field, on flights, or in poor coverage areas. It adds complexity, so we'll advise honestly on whether your use case actually needs it.
What happens when iOS or Android release major updates?+
Apps need ongoing care — OS updates, new device sizes, and store policy changes can break things annually. Our maintenance plans cover compatibility updates, monitoring, and crash fixes so your app never disappears from the stores.
Can you take over an app built by another team?+
Yes. We start with a code audit that tells you honestly what shape the app is in, then either continue development on the existing codebase or propose a phased rebuild — whichever costs you less over the next two years.
