Tailmark - Puppy Growth Diary

Your dog's everyday, marked.

Free · Designed for iPad. Not verified for macOS.

Gently keep the "now" of life with your dog. Tailmark is a growth journal that makes recording everyday life with your dog effortless. No complicated input — one tap from Home marks the day. ● Record the whole day Weight, meals (with amounts), walks, and care (vaccines, vet visits, grooming, medication) — all in one place. ● A map of memories Every photo you take appears as a round pin on the map. Your walks become a treasure map of moments. ● A word from your pup Open the app and a short message greets you — written from your dog's point of view, changing a little every day with the time and your records. ● Automatic look-backs Tailmark Monthly turns each month into a little story, with growth comparisons done for you. ● Effort becomes badges First records, streaks of days, places you've been — collect them all as badges. ● Privacy first Your data lives only in your own (and your family's) iCloud, synced and backed up across your devices. We collect nothing. No ads, no third-party analytics. ● Free forever, promised Creating records, browsing, charts, and photo storage stay free — always.

  • This app hasn’t received enough ratings or reviews to display an overview.

Bug fixes and small improvements. • Daily averages are now correct. Until now, your dog's daily average for meals and walks was always divided by 30, no matter how long you'd been keeping records — so puppies who just joined you showed numbers far lower than reality. • When you edit a repeating event, you can now choose "This event only" or "All repeats." • More units for medication (tablet, piece, packet, mL, drop, g) — useful for eye drops and liquids. • The album's photo grid now uses the full width of the screen. • Shared files were missing video memories, weight-record photos, and coat colour. They're included now. Note: whoever receives the file needs the latest version of Tailmark to open it. • Improved the reliability of iCloud sync. If something isn't working, reach us from "Contact" on your profile.
