Should I build in Flutter or go native?
Flutter when you need both stores on a limited budget and the app is made of standard screens. Native Swift or Kotlin when it depends on the device: serious camera work, AR, HealthKit, precise background location, watch apps, or platform features released this month. If you only need one platform, cross-platform buys you nothing.
How much does an iOS and Android app cost?
It depends on how many screens there are, whether it needs accounts and payments, and whether it has to work offline. Cross-platform costs less than building twice, though not half, because store submission and platform-specific work still apply to both. Message me on WhatsApp with what the app needs to do and I will scope it properly and price the whole job, fixed, before anything starts.
Flutter or React Native?
Flutter if the app is UI-heavy and you want the same behaviour on both platforms with fewer surprises. React Native if you already have a React and TypeScript web app to share logic with. Both are production-grade; team skills usually decide it.
Do I actually need an app, or would a mobile website do?
You need an app when you need push notifications, offline use, device hardware in the background, or a place on the home screen. If none of those apply, a fast mobile web app ships sooner, costs less and skips store review entirely. Plenty of businesses pay for an app when what they needed was a better mobile site.
Can you take over an app another developer started?
Yes. It starts with a technical review: what is there, what is safe, what is worth keeping. Half-finished apps from agencies and AI builders are a large part of what I pick up.
How long does an app build take?
A focused first version is typically 10 to 16 weeks including store submission, depending on how much backend it needs behind it. Apps with offline sync or payments sit at the longer end.
Will my app work offline?
If it needs to. Data lives in a local SQLite database on the device, with a sync layer that reconciles with the server when a connection returns and a conflict rule agreed up front. Field service, delivery, inspections and warehouse apps all need this.
Do you handle App Store and Play Store submission?
Yes, including signing, privacy and data declarations, screenshots, TestFlight distribution and dealing with review rejections when they happen. It is part of the build, not an extra.
