Dirty Alpha
It's an interval timer. You set work time, rest time, and rounds. You press start. It goes. That's the whole product.
No account. No app. No "pro tier" where the pro tier is just the thing working. No ads. No tracking. No cookie banner because there's nothing creepy in the cookies—just your last two workouts so you don't have to set them up again.
Workouts live in the URL. Every setting is encoded in the link. Bookmark it, share it, text it to someone who won't use it.
Keyboard-native if that's your thing. Mouse-only if it isn't. Finishes with a dumb motivational quote. It's one HTML file. View source. It's all there.
Free. Fast. That's it. Go train.
