If your cat has chronic kidney disease (CKD, what a lot of owners still call CRF), you already know the routine. The weigh-ins. The water bowl you keep half an eye on. The food dish. The sub-Q fluids. TendTail keeps all of it together, so the things that matter don't slip past you. It does one thing: helps you give your cat more good days, and helps your vet see the whole picture. WHAT YOU CAN TRACK β’ Weight, water, appetite and sub-Q fluids, in a few taps a day β’ Medications, and the days you actually gave them β’ Vet visits and the renal bloodwork your vet watches: creatinine, SDMA, phosphorus, BUN and more β’ A symptom or a quick note the moment something feels off SEE THE TREND, NOT JUST TODAY One weigh-in doesn't tell you much. Weeks of them tell a story. TendTail charts weight, appetite and water over time so you can see whether the numbers are trending up or holding steady, and catch a slow drop early, while there's still room to act with your vet. A CLEAR RECORD FOR YOUR VET When a check-up comes around, export a clean, readable PDF with the trends, bloodwork and notes together, and share it however you like. No more scribbled numbers, or trying to remember when the appetite changed. BUILT FOR THE LONG HAUL β’ Reminders you can miss without breaking anything. A skipped day is just a skipped day. β’ More than one cat? Add as many as your household needs. β’ Plain language, no jargon. β’ Made for cats with CKD, and just as useful for any senior cat whose health you're watching closely. YOUR DATA STAYS YOURS TendTail keeps your cat's health records on your phone. No account, no sign-in, and your cat's data never leaves your device. The only thing we collect is anonymous usage stats β never your cat's health data β to help improve the app. No ads, and we'll never sell your data. A NOTE FROM US TendTail is a tracking and record-keeping tool to use alongside your vet. It doesn't diagnose or treat anything, and it isn't a substitute for professional veterinary care. Always talk to your vet about your cat's health. Made by a cat person, for cat people.

Verdict
The clearest difference is in-app purchases: CKDKitty at none against TendTail's 1. TendTail's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.6). On price, update cadence and ads there is nothing between them.
