Questions

The short answers

Do I need to know how to code?

No. You describe the tool in plain words — Arabic or English — and Leanfinit builds it. There’s nothing technical to learn.

Where do my apps live?

Inside the Leanfinit app, on your device. Every mini-app you build lives in one place — the Leanfinit app — private by default, working offline, and belonging to you. Nothing is published to a store or parked on a public server.

Do I have to publish anything?

Never. No App Store, no review, no deploy. The apps you build are for you to use — that’s the whole point.

How is this different from an app builder?

App builders help you ship software to other people. Leanfinit makes software you already own and use the moment you describe it. Different job entirely.

When can I use it?

We’re in closed beta. Build something now, sign in to keep it, and leave your contact — we’ll send your link the day we launch.
