About this service
Most mobile app development for small business goes wrong the same way: an agency quotes a native build for each platform, the budget doubles, and the project stalls. We take a different path. For most SMBs, one cross-platform codebase in Flutter or React Native covers iOS and Android at a fraction of the cost, and we recommend native only when your app truly needs it.
Larkwell Systems is a US-registered company with a senior global engineering team, which is how we offer experienced app developers at rates small businesses can afford. We handle the whole journey: scoping the idea, designing screens people understand, building and testing the app, getting it through App Store and Google Play review, and supporting it after launch.

Cross-Platform Apps (Flutter & React Native)
One codebase · Two stores
One codebase, both platforms, one budget. For most small business apps, Flutter or React Native delivers near-native speed and feel for far less than building two separate native apps. It's where we start most projects, and we'll tell you plainly if native fits better.

Mobile app questions, answered
Honest answers — including the ones about price. Tap a question.
How much does it cost to build a mobile app?
Scope drives price more than anything else. In the US market, mobile apps typically run $30,000 to $120,000 depending on complexity. Mobile app development for small business usually lands in the lower half of that range, especially with a cross-platform build and our senior global team model. We scope first, then give you a clear, itemized quote before any code is written.
Should I build for iOS, Android, or both?
Usually both, through one cross-platform codebase. Your customers are split across iPhone and Android, and Flutter or React Native lets you serve them all without paying for two separate apps. We recommend a single-platform native build only in specific cases, like apps that depend on deep hardware features or Apple-only integrations. We'll walk through your audience and use case before recommending a path.
How long does mobile app development take?
A focused first version typically takes 3 to 4 months from kickoff to launch, and larger apps 5 to 8 months. Timelines depend on scope, integrations, and how quickly decisions get made on your side. We work in two-week sprints with a working build you can try at each step, so you see progress instead of waiting for a big reveal.
Do you handle App Store and Google Play submission?
Yes, end to end. We prepare your developer accounts, store listings, screenshots, and privacy disclosures, then manage submission and respond to reviewer feedback until the app is approved. Apple's review in particular can trip up first-time publishers, and we know how to avoid the common rejections. After launch, we handle version updates through the same process.
Can you take over an existing app from another developer?
Yes, this is common. We start with a code and infrastructure audit so you know exactly what you have, then give you a straightforward read on whether to improve the existing app or rebuild parts of it. Bring whatever access you have, even if it's incomplete; we regularly untangle handovers where the previous developer left little documentation.
