Why PillTail
Why PillTail
Whether it’s a daily allergy pill, twice-a-day insulin or a two-week course of antibiotics, the hard part isn’t remembering that your pet needs medicine. It’s remembering whether today’s dose already happened. PillTail takes that worry off your mind.
Reminders that follow through
- A reminder when each dose is due, and a gentle nudge 15 minutes later if it hasn't been marked.
- Mark it Given or Skip right from the notification, even from the lock screen.
- Daily, every few days or specific weekdays, as many times a day as you need.
A record you can trust
- Today's doses at a glance, grouped into morning, afternoon and evening.
- Early and late doses are noted, and skipped doses keep their reason: vomited, refused it, vet advised, ran out, or your own words.
- Tapped the wrong thing? Undo it instantly, or fix an older record. Every edit is kept.
Made for your pet, and your vet
- A photo and a 30-day on-time rate for each pet.
- Export a clean PDF of a pet's medication history to bring to the vet (PillTail Plus).
- Light and dark mode, easy on the eyes at 6am or midnight.
Private by design
Your pet’s records stay on your iPhone. PillTail has no account, no sign-up, no servers, no ads and no tracking, and Apple’s privacy label for it reads “Data Not Collected”. Reminders are scheduled on your phone, so they keep working without a signal.
