Can I set my own range?

Yes — tap the start or end number at the top and type any minimum and maximum.

Can the same number come up twice?

Yes. Each generation is independent, so repeats are possible — that's how randomness works.

Does it work on my phone, and offline?

Yes. It runs in any modern browser on phone, tablet or computer, and once the page has loaded it keeps working without a connection. For a Home Screen shortcut and a widget, install the free iOS or Android app.

Completely free, no signup. There's also a free iOS and Android app.
