Life has a lot of moving parts. People who need remembering, things that need maintaining, dates that quietly matter. Zosia keeps track of all of it, in one place, on your phone — so you can stop carrying it around in your head.

Family•Pets•Plants•Cars•Home•Documents•Occasions
The people you look after, with birthdays and ages, so nobody’s day sneaks up on you.
Vet visits, vaccinations, microchip and license, all on the pet’s own page.
Each plant gets its own watering schedule and care log. No more guessing.
Service by kilometers or by months, whichever comes first. Furnace filters too.
Passports, licenses, warranties. Zosia reminds you before the date, not at the airport.
Plan the party with guests, tasks and a budget. Grocery lists free; gift, packing and more with Pro.



Ten screens from the app itself.

Prices shown in USD and may vary by region. Pro is purchased separately on iOS and Android — Apple and Google don't share purchase records, and Zosia has no account system to bridge them. That's the same thing that keeps your data private.
🔒
Zosia is offline by default. Your information lives on your phone and we never see any of it — not the photos, not the birthdays, not a single row. Back up whenever you like to an encrypted file only your password can open, and take it anywhere.

Fade to sleep. Your phone is the lamp.
Pick a warm glow and a sleep sound, set a timer, and LumaNight slowly dims to dark as you drift off, while the sound keeps playing. Wake in the night and one tap brings a soft glow back.
