Pet Medication Tracker With Honest Partial-Dose Logging, Refrigerated-Med Warnings, And Multi-Caregiver Family Sharing
Pet owners managing chronic-illness dogs and cats hate the existing pet-care apps because they assume rigid scheduling and full doses. Real life is 'cat ate half her gabapentin and spat the rest into the carpet at 7:45.' Dev posts and app reviews surface specific gaps: no partial-dose logging, no warning when an insulin pen has been out of the fridge too long, no way to handle 'my spouse fed her, did she get the morning prednisone?' coordination. ZooMinder, Notepet, and PetDesk each solve one slice.
Start with feline diabetes. It's the highest-information-density use case (BG curves, insulin from-the-fridge timing, dose-by-the-quarter-unit, spousal handoff) and the community on r/Diabetic_Cats will eviscerate any product that doesn't get it right. If you ship something that subreddit endorses, you've got distribution into every chronic-pet community automatically.

Three categories of pet meds get badly served: chronic conditions (epilepsy, diabetes, kidney disease) where dosing is precise, refrigerated injectables, and households where two humans rotate care duty. A focused dog/cat med app for chronic patients that solves all three would have an obvious paying audience among the r/Diabetic_Cats and r/EpiDogs communities.
