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. โข Nine hourglass shapes, all free. Start with four free seasonal sand colors. โข Presets for 1, 3, 5, 10, 25 or 60 minutes, or set your own time. Pause and resume anytime. โข Sand-only view while you focus. Add a short note when a timer finishes. โข 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 โข Four precision modes in one app โ pick the right tool for the job instead of switching apps โข Clean, high-contrast gauges that are easy to read at a glance, indoors or out โข Live percentage and angle readouts, not just a vague bubble position โข Light and dark themes โข 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.

Verdict
The clearest difference is in-app purchases: 4Pro Level Tools at none against Sunadokei's 1. 4Pro Level Tools also leads on ads (none vs shown) and update cadence (daily vs every 5 weeks). On price there is nothing between them.
