Tina & Marin: Health Diary
Multi-cat health log & stories
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Log meals, water and litter for each cat, and every night they chat about the day. Not sure who it was? It stays unknown. Everything stays on your iPhone.
Every night, your cats chat about the day.
You put food down, refreshed the water, cleaned the litter box. Keep a quick record of those small moments, and at night your cats start talking: "So, about today..."
Lines that come from your records carry a paperclip mark. Lines without it are the cats' daydreams. You can always tell what really happened and what is just a story, and a "facts only" switch hides the story whenever you like.
On a worrying day, such as a day with vomiting, the cats don't joke around. They quietly look out for each other, and when a record looks worth a closer look, a card above the story suggests contacting your vet.
AN HONEST DIARY FOR MULTI-CAT HOMES
Two empty bowls don't mean both cats ate. And sometimes you simply didn't see who used the litter box.
This app never guesses. If you didn't see which cat it was, the record stays "unknown". Later, you can answer "Who was it?" in the Detective tab, or leave it unknown.
WHAT YOU CAN LOG
- Meals: dry and wet food together, with the result (all / half / a bite / just sniffed / not interested) added later
- Water checks
- Litter: poop and how it looked, and pee
- Vomiting: how many times you saw it, and what it contained
- A note on any record
- The Log shows each day, one cat at a time
TODAY'S SNAPS
Pick a few photos and add a one-line memo, then look back by date. Photos are copied into the app and stay on your iPhone.
EACH CAT'S PERSONALITY
Choose traits for each cat: foodie, cuddly, wary, mischievous, laid-back and more. Pick what your cats call you, too (Mom, Dad, or your own name). The nightly chat speaks in each cat's own voice.
TINA & MARIN PLUS
With Plus, the nightly chat becomes a longer scene of 6 to 10 lines. The cats talk about everyday life using the day's food names, how much was eaten, water checks, your snap memos and each cat's personality. The scene is different every night.
Recording, snaps, Detective and the Log stay free, with or without Plus.
PRIVACY
