Mobile App Development
As a mobile app development company, we design and build apps people want to open: fast, intuitive and reliable across devices. With cross-platform tools we ship native-quality iOS and Android apps from one codebase, which keeps your cost and time to market down.
(01)Overview
What is Mobile App Development?
Mobile app development is designing and building native or cross-platform apps for iOS and Android that are fast, intuitive and ready to scale as your user base grows. Arrowbin builds them for startups and businesses taking a product to mobile, and a focused MVP usually reaches the stores in 10–16 weeks.

(02)One codebase
One app, feels native on both
Same codebase. Notch, navigation, gestures and payment button adapt to each platform automatically.
(03)Device features
Everything the phone can do
The features that make an app worth installing instead of a bookmarked website. We build them natively, on both platforms.

Timely, segmented nudges that bring people back, not spam.
Offline mode
Works on a bad connection and syncs when it's back.
Camera & scanning
Photos, documents, QR and barcode scanning built in.

(05)Process
How we deliver
We prototype before we code, and test on real phones before anything goes to the stores.
- 1
Step 011–2 weeks
Define
We agree on the feature set, the platforms and what the MVP needs to do.
- 2
Step 022–3 weeks
Design
We prototype the flows and the interface before any code.
- 3
Step 036–10 weeks
Develop
We build, integrate and test on real devices, where the bugs show up.
- 4
Step 04Ongoing
Ship & iterate
We launch to the stores, then improve the app based on how people use it.

(07)How we work together
Three ways to start
Start with a fixed-scope MVP. Once the app is live in the stores, choose a team for new releases or a care plan for upkeep.
- Most popular
Project
An MVP for iOS and Android, with a fixed estimate.
Best for a first app or taking a product to mobile.
- Feature set agreed before design
- Clickable prototype before code
- Store submission handled
- For growing products
Product team
A team shipping app releases on your roadmap, month to month.
Best for apps that update often after launch.
- App and backend built by one team
- Releases through both stores
- Changes based on how people use it
- After launch
Care plan
Updates and fixes so the app keeps passing store review.
Best for live apps with real users.
- Updates for each new iOS and Android
- Crash and error monitoring
- Store listing and policy checks

For most products, cross-platform (React Native or Flutter) gives you native-quality results from one codebase and saves 30–40% versus building each platform separately. We only push for fully native when an app is heavy on performance or hardware.
A polished MVP usually lands between $12,000 and $40,000, depending on the features and integrations. We give you a fixed estimate once the core feature set is defined.
Yes. We handle the whole release: store listings, review compliance, builds and updates, so your app goes live without the usual headaches.
A focused MVP usually takes 10–16 weeks from kickoff to the stores: about 1–2 weeks defining scope, 2–3 weeks of design and 6–10 weeks of development and testing. Store review then takes anywhere from a day to a week.
Yes. We cache the data people need most, queue their actions while they're offline, and sync everything when the connection returns, so the app stays usable on a poor network.
You do. The source code, the App Store and Google Play developer accounts and all app data belong to you. We work inside your accounts, never ours.
