About

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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://apps.tmkm.dev/chek/privacy For anyone who wants a simple way to keep a few habits going.
