Medication Adherence
I was diagnosed with Crohn's disease and quickly realised how hard it is to remember everything between appointments. What did I eat that week my symptoms flared? Was I actually taking my medication consistently? How has my sleep been?
I tried notes apps, spreadsheets, even paper journals — nothing stuck. And when I sat down with my gastroenterologist, I could never give them a clear picture. I always left feeling like we could have had a better conversation if I'd had the right data ready.
So I built IBDLens — the app I wish I'd had from day one. It's designed specifically for IBD, tracks everything that matters, and generates reports your doctor can actually use.
If you're living with Crohn's or colitis, I hope this helps you take a little more control. You deserve tools built by someone who gets it.
