The group chat, replaced.

One tap, and everyone knows it's handled. Nobody feeds twice.

Without a shared system, a family chat fills with "Did you feed the dog?" and "I thought you did?". In Collie, the evening meal shows as completed by Alex at 7:05 PM, and when Maya taps Done again at 7:12 the second tap is ignored.

What about his meds?

Why Collie

Less coordinating, more time with your pets

Reminders, routines, and who-did-what, handled. Pet care stops feeling like a group project.

Cooper · Evening meal

Completed by Alex · 7:05 PM

Maya almost fed Cooper too · saw it was already done

Know it's done, and by whom

Tap Done and everyone sees the name and the time. A second tap is ignored, so nothing gets doubled.

Nothing slips through

Turn on Remind until done for any task, from meds to the litter box. The reminder repeats until someone marks it done, at the interval you pick. On by default for meds.

Keep track of everything

“When did that start?”

Everything anyone at home notices, on one timeline. When the vet asks how long it's been, you have the dates.

  • Log it in a few taps, with a note or a photo.

  • Save your own tags, like “Ate grass”, then filter by pet or tag to see how often it happens.

  • Walk into the vet with real dates, not “a few weeks ago”.

  • Good news counts too: a first walk without pulling, a training win.

Collie keeps the record. It never interprets it or tells you your pet is fine.

For owners and sitters

Pet handoff without the five-paragraph text.

Your sitter opens the same live list in Collie, with the routine, meds, and vet already there. You see every visit as it happens.

  • No briefing to write. It's already in the app.
  • Every walk, meal, and dose shows up live, with a name and the time.
  • Updates and photos from every visit, kept with your home.

How pet access works, safely.

Invite-only

Only the invited person, verified by email, can open the handoff.

Time-bounded

Every share has a start and end. Access closes on its own.

Revocable

Plans change? The share can be ended in a tap and access stops immediately.

Nothing deleted

Every completion and note stays with the household, for good.

Common questions

Everything you need to know about Collie. Can't find what you're looking for? Get in touch.

Is Collie free to use?

Yes, completely. Every feature is free: all five task types (meals, meds, walks, appointments, custom), reminders that repeat until a task is done, push notifications, household sharing for up to 5 caregivers, sitter sharing, and advanced scheduling, with up to 10 pets. No subscription, no paywall, no credit card.

Does Collie work for cats, dogs, and other pets?

Yes. Every species is a first-class pet in Collie. Dogs, cats, rabbits, birds, reptiles, small mammals: it's one app for the whole household, regardless of who shares the kitchen. (Most other pet apps are dog-only.)

How does household sharing work?

It's free. Send a link (or show a QR code) to invite up to 5 caregivers to your household. Everyone sees the same tasks, updated live when someone completes one. Anyone in the home can add pets and tasks. Admins manage who's in the home, and a home can have more than one admin.

What does my sitter see?

Your sitter opens the handoff in the Collie app and sees the pets you shared, today's tasks, feeding and medication details, your notes, and your vet contact. You see each task they finish in real time, and they can post an update with notes, photos, and their visit times. Each share has a start and end date and closes on its own.

Can I keep track of things I notice about my pet?

Yes. Collie has a shared journal: anyone in your household can log what they noticed about a pet, tag it (didn't eat, watery poo, limping, happy, good news, and more, or tags you create yourself), and add a note or a photo. Every entry keeps the pet, the person and the time, so the whole household sees the same history and you can look back and see when something first came up. It is a record you keep and can show your vet. Collie does not interpret entries, suggest conditions, or tell you whether your pet is fine. If you need clinical vitals tracking, charts, or vet-ready PDF exports, a dedicated pet health tracker will serve you better.

Do reminders keep going until a task is done?

Yes, if you want them to. Turn on Remind until done for any task and Collie repeats the reminder until someone marks it done: every 5, 10, 15, 30, or 60 minutes, up to 6 reminders. It's on by default for medication, every 10 minutes. Meds always get their own notification, never grouped with other tasks, and one medication task can cover several pets on the same dose.

Can I pause notifications when I'm away?

Yes. Turn on Pause notifications in Settings and Collie stops your other task reminders on all your devices until you turn it off. Medication reminders and your sitter's updates still come through, so a dose never goes quiet.

Can I schedule things like 'every 28 days' for flea meds?

Yes, and it's free. Collie has flexible recurrence built for real pet routines: every N days (2 to 30) for whatever cadence your life actually runs on, whether that's a flea med every 28 days, grooming every 10 days, or a brush-out every 3; every other week on a chosen weekday for chores like litter deep-cleans or baths; and multi-day weekly patterns. Most calendar apps cap at simple weekly or monthly, which doesn't fit pet life.

Can two people accidentally complete the same task?

No. Collie uses first-write-wins: the moment someone marks a task done, everyone else instantly sees "Completed by [Name] at [time]." A second tap is silently discarded. No duplicates, no confusion, no more double-feeding.

What happens if I'm offline or your servers are down?

Both cases are covered. You can still open the app, see today's tasks, and mark them complete from your cached data, whether you've lost signal or our servers are temporarily unavailable. Collie syncs everything the moment things recover. If someone else completed the same task while you were offline, Collie handles it gracefully with no errors and no duplicate entries.

Is Collie available on Android?

Yes. Collie is on Google Play for Android and on the App Store for iOS. Download for Android. Everything syncs across both, so a household can mix iPhones and Android phones.
