Sumday
Habits, quantities and money — your whole month at a glance. Private, on your phone. Pay once.
Tap to log
One tap to check a habit. Plus and minus for litres, pages, rupees. Built so anyone in the house can keep the diary, including people who would rather not type.
Bills that add themselves
Give milk, the newspaper or house help a rate. Sumday totals the month. Export a PDF when you settle.
Your month, one glance
A week board and a month heatmap for every tracker. Skip a day without breaking the streak. Correct yesterday when you remember.
Private by design
No account required. No ads, no analytics. Your data stays on the phone. Optional backup only if you ask for it.
Made for the fridge diary
Milk deliveries, newspaper, tiffin, house help, water cans — and gym, water, sleep if you want those too. One app instead of a paper tally on the fridge.
On iOS and Android
Sumday is on TestFlight and Play closed testing. A free tier tracks five things and one vendor bill. Pro is a single lifetime purchase — no subscription.
