Turn your iPhone into a level, angle finder and AR measuring tool. No account, no tracking – for DIY, construction and everyday projects. Ninety turns your iPhone into a measuring tool for construction, DIY and everyday projects. Level surfaces, measure angles and slopes, check right angles, measure distances and compare heights – all in one app. Traditional measurements use the iPhone's built-in sensors, while AR lets you measure directly in the camera view. LEVEL & SLOPE • Level surfaces • Check boards, battens and edges • Set target slopes in %, degrees or mm/m • Use audio and haptic feedback • Calibrate the sensors for precise tilt measurements ANGLE & PLAN • Measure angles and inclines • Set targets such as 90°, 45° or any custom angle • Set out a right angle from an existing wall • Set and transfer reference angles • Use the gyroscope for plan-view measurements AR MEASUREMENT • Measure distances directly in the camera view • Add multiple measurement points • Display corner angles automatically • Measure individual segments and total distance • Save measurements for later HEIGHT & REFERENCE MARK • Set a reference mark for height measurements • Compare heights at different points • Check excavation, paving and screed against a target level • Scan floor areas to visualise height differences • Record measurement points in a height log 3-4-5 CHECK Verify right angles with a tape measure. Enter two sides and 90° calculates the required diagonal. You can also check rectangles by comparing their diagonals. BUILT FOR OUTDOORS Outdoor Mode uses high contrast and large digits to keep measurements easy to read even in direct sunlight. Ideal for decks, patios, foundations, fences, tiles, screed, roofs, furniture, renovation and many other DIY and construction projects. NO ACCOUNT. NO TRACKING. 90° is free. No account, no tracking and no in-app purchases. Your saved measurements stay on your iPhone. Please note: Sensor and AR measurements depend on your device and environmental conditions. For safety-critical or highly precise work, verify measurements with an appropriate professional measuring tool.
