Sunadokei
Read full descriptionHide full description
Sunadokei is a sand timer you can read at a glance. Pick a time and the falling sand shows how much is left, whether it is a study block, a short break, a workout set or something on the stove. When you would rather not watch numbers, switch to a sand-only view. • Nine hourglass shapes, all free. Start with four free seasonal sand colors. • Presets for 1, 3, 5, 10, 25 or 60 minutes, or set your own time. Pause and resume anytime. • Sand-only view while you focus. Add a short note when a timer finishes. • History and accumulated sand show the time you have put in. Home Screen widget included. Free with ads: a banner on the main screen and full-screen ads that may appear after finished timers. Sunadokei Pro is a one-time purchase, not a subscription: 10 more sand colors and no ads. See the purchase screen for the current price.
