## What is chek?

Most habit apps turn one missed day into a broken streak. chek doesn't keep score. Mark what you did, see what you've built up, and get on with your day.

chek stays simple on purpose: add a habit, tap it done, and watch the pattern build in a calendar and a heatmap. That's the whole app.

TODAY

— One tap marks a habit done, a second tap clears it
— Add a value when it matters: minutes meditated, pages read
— Skip a day without it counting against you
— Mark yesterday from the same screen if you forgot

HISTORY

— A month calendar that fills in as your days do
— A heatmap for every habit, side by side, so you can compare them
— Totals for the week, the month or the year

REMINDERS

— A quiet nudge at the time you choose, only on days the habit is scheduled
— Already logged it? The reminder stays silent
— Several habits at the same time arrive as one notification

PRIVATE BY DEFAULT

Everything stays on your phone. There is no account, no sign-in and no ads. Export a backup file whenever you like and import it on a new phone.

Settings covers the basics: week start, backup, reminders, and a different app icon if you want one.

chek PRO

A one-time purchase, not a subscription. Free includes logging, skips, history, reminders and backup for up to five habits. Pro removes the limit and includes every Pro feature added later.
