When did you last change the AC filter? Take the dog to the vet? Wash the bedsheets?

Dayback remembers for you. It's a simple "days since" tracker for the things you do every now and then — the ones that never fit in a daily habit app.

NO STREAKS. NO GUILT.
Habit trackers expect you to do things every day and punish you with broken streaks when you don't. Real life isn't like that. Some things happen every few weeks, others twice a year. Dayback just shows how long it's been, quietly, without pressure.

HOW IT WORKS
• Add the things you want to keep track of — in seconds.
• Tap ✓ when you do it. That's it.
• See at a glance: "12 days ago", "4 months ago".
• Forgot to log it? Add any past date, with an optional note (like "45,200 km" or "Vaccine V10").

LEARNS YOUR REAL RHYTHM
You don't need to set a schedule. After a few logs, Dayback learns how often you actually do each thing — "every ~6 weeks", "every ~3 months" — and uses it for gentle reminders around the usual time.

SYNC ACROSS YOUR DEVICES
Turn on sync and your events stay up to date on all your Android devices, safely backed up in your own Google Drive. Switching phones? Turn sync on and everything comes back. Dayback keeps it in a private app folder that only the app can use — we never see your data.

HOME SCREEN WIDGETS
Check how long it's been without opening the app, and log with one tap right from the widget. Choose which events it shows, resize it from a single tile to the full row, and pick a light, dark or transparent look.

YOUR WHOLE HISTORY
• Calendar view: tap any day to see what you did.
• Rhythm chart for each event: shortest, longest and usual interval.
• Full log history with your notes.

MADE FOR THE EASY-TO-FORGET STUFF
• Home: AC filter, bedsheets, deep cleaning, smoke detector, fridge.
• Car: oil change, tires, registration, car wash.
• Health & self-care: dentist, check-ups, haircut, contact lenses, medication refills.
• Plants & pets: watering, repotting, vet visits, flea treatment, grooming.
• Family & life: calling your parents, bills, renewals.
Organize everything with categories — use the built-in ones or create your own — and pick from more than 170 icons and 16 colors.

PRIVATE BY DESIGN
• No account, no sign-up.
• Your events and notes stay on your device — or, with sync on, in your own Google Drive.
• No ads.
• Export a backup file whenever you want.
• Works offline.
