Journal
Capture is always one tap away. Add a photo, tap a mood, jot a note — or just the photo. Your days stack up chronologically, grouped and ready to revisit.
A home for your cat's whole life
The place your cat's story becomes a timeline.
NekoSense AI builds beautiful, private software for cat parents. It starts with NekoDiary — a free journal & keepsake for the one who rules your home.
Now on the App Store. iPhone · Free · No ads · Your data stays yours.
Free, forever on the diary
Private by design
Yours to keep & export
Made for cats, never "pets"
Meet NekoDiary — a free cat journal app
Baby book meets Day One — for your cat.
One moment a day is all it takes. A photo, a mood, a note. Everything you keep becomes a single, beautiful timeline of a life — the one you'll be so glad you saved.
Three ways in, one timeline
Simple to write. A joy to look back on.
NekoDiary is built around a single idea — the timeline of your cat — read three ways.
Memories
A scroll from your cat's very first day to now. Milestones, favorite photos and monthly recaps — a keepsake that reads like a book, and a share card ready for the group chat.
Cats
Your source of truth for each cat: breed, birthday and gotcha day, weight, microchip, vet details — plus vet visits, vaccinations and records kept safely in one place. Export it all whenever you want.
Your cat's story belongs to you.
Every moment lives in one calm, private place — yours to keep and yours to export, anytime. No ads, ever. Just a beautiful home for the life you're living together.
