4Pro Level Tools — 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 — not just which way to nudge. CIRCULAR MODE A bullseye-style dial for surfaces that need to sit flat in every direction — 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 — 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 • Four precision modes in one app — pick the right tool for the job instead of switching apps • Clean, high-contrast gauges that are easy to read at a glance, indoors or out • Live percentage and angle readouts, not just a vague bubble position • Light and dark themes • Works entirely offline — 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.
