Task Chart is a planner app where your plan is written on one big sheet of paper. ■ One sheet Goals and tasks live together on a single sheet, nothing abbreviated. The phone screen is a window onto that paper. Pinch to zoom, pick a task up with your finger and rearrange it — you see where everything will settle before you let go. ■ Day by day Tap a cell and record the day in one stroke — a check, or a number. The row and the day light up in a quiet cross. Past days turn like a scroll under your finger. ■ Quiet by design No advertising. No tracking (only anonymous usage counts, which you can turn off in Settings). No badges, no streaks, no flames. Just paper and ink. ■ What you write is yours The notebook is stored on your device only, and you can export it to a file at any time. If you stop subscribing, everything you wrote stays readable. Nothing becomes unreadable. ■ About the subscription Writing — creating and editing tasks and records — requires the Task Chart subscription (US$0.99/month or US$11.99/year; prices vary by region). Reading and exporting are free without one. The first 14 days are free for new subscribers. Unless you cancel at least 24 hours before the free period ends, your Apple ID is charged for the period you chose, and it renews automatically until you cancel. You can cancel any time in iPhone Settings. If you purchased the earlier paid version, please contact support.
