The whole model,

The same model, in your pocket

Not a mobile skin over the site — the rankings, the confidence intervals and the simulations, rebuilt native. Follow crews and the app opens on them.

Race day, on your Lock Screen

A Live Activity tracks the final while it happens: who's leading, by how many lengths, how far to the line. No app to keep open.

Widgets that stay current

Your league's outlook on the Home Screen, updated after every regatta. Long-press to switch which league it watches.

What you’re signing up for

Why do you need my Apple ID email?

TestFlight and this site don't share a login, so an Apple ID is the only thing that ties a beta tester to an RPI account. We use it to match you up and to send the TestFlight invite — nothing else, and it isn't added to any mailing list.

What does JV actually unlock?

Head-to-head matchups, championship simulations, the full Power 10, ten favourite crews instead of three, and the pick'em leaderboard. It works on the site and in the app.

What happens after 30 days?

You go back to Free. There's no card on file and no auto-renew — nothing to cancel, and nothing gets charged. Everything you followed or picked stays put.

It's a beta. How rough is it?

Rough in places. Things will look wrong, and something will break. That's the point of a beta — tell us what you hit and it gets fixed.

If I subscribe inside the app, am I charged?

No. TestFlight purchases run through Apple's sandbox, so subscribing to JV or Varsity in the beta costs nothing — it's a free way to try the paid tiers. Sandbox subscriptions also 'renew' every few minutes rather than monthly, which is expected, and they don't carry over to the real App Store release. Anyone who subscribes during the beta gets a thank-you at launch.
