Winnie
A shared care app for my dog that turned into a record of him growing up.
Winnie is our cavapoo. My fiancée Kimberly and I share looking after him, and this is the app we use to do it.

It started in Notes
When Winnie came home in October 2025, Kimberly and I kept a shared Apple Note of everything he did. It worked, but all we really wanted to know was when he last went out, whether he'd eaten, and who did what.
- Every pee and poop, with the time and inside or out
- Meals, naps, walks and training
- Our own emoji shorthand by December
The first version
The first version gave the Note some structure:
- Time since his last pee and poop
- His wake window
- One-tap logging with an undo
- Tags for inside or out, accidents, and who took him
Two more tries
- In May, a storybook look, with Sims-style bars for bladder, poop, energy and hunger
- Rebuilt for sharing in September, with reliable sync, who did what, a ping when the other person logs, a shared fridge for notes, and a tiny pixel Winnie in the corner
A room that's actually his
In October, Today became a pixel version of our living room, with his real stuff in it: the cream sofa, the arch lamp, his crate and pink bed, Snuggle Puppy.
- He naps, eats and goes on walks based on what we log
- The window shows the real sky and moon
- His closet has his actual outfits: a blue bandanna, his harness and a striped shirt
- Pee and poop are the two big buttons, since they're what we log most
Winnie's closet
Pick his outfit.
His harness comes on for bathroom trips. Then he returns to your pick.
Care photos became his story
Logging a poop asks for a photo, which you can skip. Those photos and the ones we import land on one timeline, with his age at every point since the day he was born.
- Kimberly and I can each add our own memory to the same moment
- Once a year it makes a small album, one cover photo per month
He's on TikTok too
The app is the private record. His TikTok is the public one, more than 150 videos of him growing up.

Insights only describe what we actually logged.
- Months with only a few logged days show as hollow dots
- Dashed lines mark when the way we logged changed
- Two months only get compared if both have two weeks of data
Plans
- Food counts down a meal at a time, with a reorder link
- Stock checks for wipes, poop bags and his heartworm meds
- It reads our Google Calendar, but a vet visit only counts as care once one of us confirms it
Where it's at
- Most of the changes came from using it every day
- It's a web app on both our phones, built in plain JavaScript on Netlify, and it works offline
- Thousands more photos of Winnie still to add
Screens are from our phones. The May and September screens and the clips use demo data. The app is private to our household.
