I Got a Cosmetic Procedure and It Made Me Build a Poop App

Mesotherapy wrecked my digestion, every bowel tracker on the market felt like a hospital form, so I built HYPT: a free, five-second bowel diary on the Bristol stool scale.

When every tracker on the market feels like a hospital form, sometimes you just build your own.

I got mesotherapy done a few months ago. Fat dissolving injections, nothing dramatic, just one of those things you do and move on. Except my body decided not to move on. My digestion went completely irregular and I had no idea what was normal anymore.

So I did what anyone would do. I tried to track it.

Every app I found felt like it was designed for a clinical trial. Cold interfaces, medical jargon everywhere, and half of them locked basic features behind a paywall. I just wanted to know if I'd had a normal week. I didn't want to feel like I was filing a report to the NHS every time I opened my phone.

So I built one.

HYPT, short for "Have You Poo Today", is a free webapp that tracks your bristol stool scale, lets you export the data to hand to your GP, and finds the nearest GP from your location. That's it. No subscriptions, no premium tier, no "upgrade to unlock your bowel history." It's free and it's staying free.

The design was important to me. I wanted something that felt fun and a bit retro, not sterile. Something you'd actually open daily without feeling like a patient. But underneath the aesthetic, the data is genuinely useful. If you have IBS, Crohn's, UC, or anything that makes your gut unpredictable, having a clean export to show your doctor is worth more than another symptom diary that looks like a spreadsheet.

Everything is encrypted. I can't see your data. I don't want to see your data. This was a problem I had, I solved it, and now it's out there for anyone who needs it.

It's still in beta, so if something breaks, that's expected. If you log in with Google and see "supabase" on the screen, I'm sorry. I haven't put money into this yet. One person studio budget.

Try it at hypt.rinnr.dev and tell me what breaks.
