Crohnsworld – A Free Symptom Tracker for People with Crohn's and Colitis

Our own free web app for people with Crohn's or colitis: one tap logs each toilet visit, and every day reads back as one plain sentence for the IBD clinic.

Crohnsworld is our own product. Simon, who runs Eightlegged, has Crohn's disease. His IBD team kept asking how many times a day he went to the toilet, and he had no idea. None of the apps he tried simply counted, most wanted a subscription, and several had shut down and taken years of people's records with them.

One tap, one sentence

Logging a visit is a single tap, with the Bristol type, urgency, blood or pain added only if you want to. It works with no signal and catches up later. Every day gets a count, a colour and a sentence such as "Tuesday: 10 visits, mostly loose, blood once, 2 in the night", and the month view makes a bad week easy to spot.

Ready for clinic

It keeps the things IBD nurses and consultants ask about: visits per day, night-time visits, loose stools, blood, urgency, pain and fatigue. Everything can be exported as a spreadsheet. Crohnsworld is free, carries no advertising, and asks only for an email address and password. Deleting your account deletes everything with it.
