A gentle first tracker. No account, no email.
A gentle first-period mode with simple words, a period kit and no account or email. Nothing about a young person’s cycle reaches us.
In short: Splash is a first-period tracker for teens that needs no account, so there is no email or personal profile. It explains periods in plain English, predicts the next one as a range, and keeps everything on the phone. Parents can read our guide to first periods too.
