PocketLevel turns your iPhone into a precision spirit level and measurement toolkit. Hang pictures perfectly straight, level shelves and furniture, check slopes and measure angles — with big, sunlight-readable numbers and pro-grade accuracy. BUBBLE LEVEL Bullseye level for flat surfaces and bar level for walls and frames. The display turns green with a haptic tap the moment you hit level. Adjustable tolerance from 0.2° to 2.0°. CALIBRATION Two-step calibration against any reference surface corrects for your phone's camera bump and case — the number one cause of inaccurate phone levels. Your calibration is saved per orientation. ANGLE FINDER Full 360° protractor with live readout to a tenth of a degree. Set any angle as zero for relative measurements, and read slopes as degrees or percent — perfect for roof pitch and ramps. SAVE YOUR READINGS Freeze any reading with a tap and save it with a name, like "Top shelf" or "Table saw blade". BUILT FOR REAL WORK - Big monospace numbers you can read in bright sunlight - Screen stays awake while you measure - No ads, no popups, nothing interrupting your measurement - Works fully offline - All processing on your device — no data collected PocketLevel Plus subscription is required to use the app. Plans: $2.99 per week with a 3-day free trial for new subscribers, or $24.99 per year.
