Not tracked. No weight, glucose, temperature, blood pressure or heart rate. Collie logs what you noticed, not what you measured.
16 vitals (weight, blood glucose, temperature, blood pressure, heart rate, respiratory rate, and more).
Shared journal. Anyone in the household logs what they noticed with plain-language tags (didn't eat, watery poo, limping, happy), plus a note and photos. Every entry keeps the pet, the person and the time, and filters by pet or tag.
Daily check-in plus 17 structured log types, including symptoms grouped by body system. Deeper and more clinical, and single-observer in practice.
No, by design. Collie records observations and never suggests a condition, flags an entry as concerning, or tells you your pet is fine.
Condition Tracker organizes entries into named conditions with onset, active and resolved states.
Not offered.
Customizable PDF reports of complete health data.
Not offered.
Detailed timeline for illnesses, injuries, allergies.
First-write-wins. The first tap is recorded with name and timestamp; a second tap is silently discarded.
Multi-user collaboration documented, but real-time attribution behavior not publicly detailed.
Missed doses repeat every 10 minutes for 60 minutes on their own notification, never grouped.
Medication and treatment reminders. Escalation cadence not publicly documented.
Yes. Invite up to 2 sitters by email for exact dates. Access is limited to the pets you share, starts and ends automatically, and can be revoked anytime.

Auto-built from each pet's real routine: feeding details, medication instructions, behavior notes, your emergency vet contact, and notes for this sitter. Ready before the first visit.

Competitor details come from Petfetti's public site and US App Store listing, verified July 6, 2026. If a feature isn't publicly documented, the row says so.
Pet owners managing chronic conditions or frequent vet visits who need structured health data to share with a clinic. Strong fit if you regularly export a vitals report to take into the vet's office, or track trends in weight, glucose, or temperature over weeks and months. Both apps handle complex medication schedules and reminders; the difference is that Petfetti turns the surrounding health data into charts and a report.
Homes where more than one person cares for the pets, or a sitter steps in: mixed species, medication that has to land on time, and a clear record of who did what. If you need vitals, charts, or a report to hand a clinic, Collie isn't that app.
Both apps document multi-user collaboration with similar caps (up to 5 caregivers, up to 10 pets on the paid plans). The difference is what the collaboration is for. Petfetti's multi-user model is built around sharing health data: weight logs, condition timelines, medication schedules. Collie's is built around coordinating today: who fed the dog at 7:05 PM, who walked the cat, who still needs to give the evening pill. If your friction is logging data to share with the vet, Petfetti. If your friction is two people accidentally feeding the dog twice, Collie.
No. Collie is intentionally not a health tracker. We don't log weight, blood pressure, temperature, or symptoms. The whole product is scoped to coordinating daily care across multiple people in real time. If you need vitals tracking, charts, or vet-ready PDF reports, Petfetti is the better fit.
Petfetti documents multi-user collaboration but does not publicly detail real-time attribution behavior or duplicate-prevention semantics. Collie's behavior is explicit: the first tap on a task is recorded with the caregiver's name and timestamp, and a second tap is silently discarded with a 'Completed by X at HH:MM' message. If the duplicate-feeding problem is what you're solving, that explicit guarantee may matter.
Collie has pet sitting built in. You invite up to 2 sitters by email for exact dates; they sign into the Collie app (free for sitters) and get a briefing with each pet's routine, feeding details, meds, and your emergency vet contact. They work through the day's tasks, then post an update with notes, photos, and their visit times, which the family sees as a visit report. Access starts and ends automatically and can be revoked anytime. Petfetti's sitter-style temporary access is not publicly documented.
Yes, if you want the best of both. Petfetti as the long-term health record (vitals, conditions, vet reports) and Collie as the daily coordination layer (who's doing what, today). They're scoped to different jobs and don't overlap much.
