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. โ€ข Nine hourglass shapes, all free. Start with four free seasonal sand colors. โ€ข Presets for 1, 3, 5, 10, 25 or 60 minutes, or set your own time. Pause and resume anytime. โ€ข Sand-only view while you focus. Add a short note when a timer finishes. โ€ข 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.

4Pro Level Tools โ€” Every Way to Check Level, in One App Stop carrying a physical spirit level. 4Pro Level Tools turns your phone into a precision leveling instrument with four dedicated modes, each built for a different job. BUBBLE MODE The classic torpedo-level look. A dual-tube gauge reads both tilt axes at once, with a real-time percentage readout so you know exactly how far off level you are โ€” not just which way to nudge. CIRCULAR MODE A bullseye-style dial for surfaces that need to sit flat in every direction โ€” tabletops, tripods, camera rigs, appliances. Center the bubble, and you're level on both axes simultaneously. PLUMB MODE Check any wall, door frame, or vertical surface the way a real plumb bob does โ€” hang it, watch it settle, read the deviation. No string or weight required. PILLAR MODE Purpose-built for checking columns and posts for true vertical lean, with a live readout of degrees and percentage off-plumb. WHY 4PRO LEVEL TOOLS โ€ข Four precision modes in one app โ€” pick the right tool for the job instead of switching apps โ€ข Clean, high-contrast gauges that are easy to read at a glance, indoors or out โ€ข Live percentage and angle readouts, not just a vague bubble position โ€ข Light and dark themes โ€ข Works entirely offline โ€” no GPS, no camera, no account required Whether you're hanging a shelf, installing a fence post, mounting a TV, or checking a column during a build, 4Pro Level Tools has the right gauge ready.
