Three-tap logs
Bristol type, duration, toilet, optional GPS, all from one sheet. Works offline and syncs when you're back online.
Streaks and ranks
Ten ranks from Toilet Trainee to Cosmic Crapper. Daily streaks, XP for variety, and 46 achievements to chase.
Patterns over time
A month calendar coloured by Bristol type, deep stats with distribution charts, and a Poop Score that tells you how regular you actually are. It is your bowel movement record, made useful.
Seven shapes, one healthy zone
The Bristol Stool Scale is the clinical chart used worldwide to classify stool consistency. PUP speaks Bristol so what you log actually means something. Aim for Type 3 or 4, the healthy zone.

Every screen has one job. The home calendar is glanceable. The add sheet is a single column you can tab through one-handed. The detail view tells you whether today's log is normal, and what to do if it isn't.
