Features

Everything your gut wants you to know

Quick to log, easy to read back. Your phone does the counting, your watch can do the logging.

Calendar

Every day with entries is marked on a month calendar. Tap a day to see and edit what you logged.

Patterns

Time of day, Bristol types, colours and more, compared with the previous period so you see what's changing.

Daily reminders

A gentle nudge at the time you choose, so no entry slips through. Scheduled on your phone, off until you want it.

Map

Pin entries to where they happened and browse them on a map, grouped when they're close together. Turn maps off any time.

On your wrist

The watch app logs an entry step by step, with every step skippable, and hands it to your phone.

Sync and export

Sign in to keep your entries in step across devices, or export any date range to a spreadsheet for your doctor.

Logging

Log it in seconds, in as much detail as you like

Every field is optional. Add whatever helps you and your doctor read the story.

See the rhythm behind the routine

Pick a week, month, year or any range of dates.

  • Time of day — entries per hour, and how they split across morning, afternoon, evening and night.
  • Every value — how your Bristol types, colours, sizes, passage, observations and places add up.
  • Consistency and regularity — two scores from 0 to 100 for how even your intervals and timing are.
  • Trends — every number compared with the period before, with an arrow showing which way it moved.
  • Note keywords — the words that come up most in your notes.
Privacy

Private by design

It's health data, so it stays yours. Everything works without an account or an internet connection.

On your device

Entries live on your phone. Nothing is uploaded unless you sign in.

Optional sync

An account is only for backup and sync across devices, over HTTPS.

No tracking

Location is read only to pin an entry, never in the background.

Yours to take

Export everything, or delete your account and all its entries.
