Frequently asked questions

Another question? Write to me.

Flutter or an installable web app (PWA)?

Flutter if you want to be on the App Store and Google Play with full access to the device; a PWA to move fast, with no store review, when the app stays close to a website. The interactive diagram on this page gives you a first steer.

Do I need two apps, one for iOS and one for Android?

No. With Flutter, a single codebase produces both the iOS and the Android app; a PWA runs on both with nothing extra.

Who publishes the app on the stores?

I prepare the release and guide you through it. The developer accounts are in your name, so the app belongs to you.

Can the app work offline?

Yes, if it's planned from the design stage: data is stored on the device and synced when the connection returns.
