Hourglass Sand Timer

Hourglass Sand Timer is a full-screen sand timer that works like the real thing: turn your phone over and the hourglass flips. Pick a preset or set any time down to the second, then watch the grains fall. When the sand runs out you hear a chime and feel a vibration, and with notifications allowed, an alert arrives on time even when the screen is off. A calm sand clock for study sprints, meditation, a child's tooth-brushing or time-out, or a board-game turn. Key features - Turn your phone over to flip the hourglass, or tap the flip button - 1, 3 and 5 minute presets, plus a custom duration down to the second - A large animation you can read across the room, with digits you can show or hide - Completion sound and vibration, each with its own switch - A keep-screen-on option - Remembers your last duration Pro is a one-time unlock with no subscription: 15 and 25 minute presets, unlimited custom presets, four extra sand colors, and no banner ad.
