Point your camera at a person, a car or an animal. RangeFinder finds it, frames it and tells you how far away it is, with an honest ± range so you know how much to trust the reading. RangeFinder 4.0 is rebuilt from the ground up. No more lining up marks by hand: on-device AI detects the target for you, and a new measuring engine checks every reading three ways. HOW IT MEASURES • Height first: RangeFinder knows how tall a standing adult, a car or a horse typically is, and measures the angle from its top to its bottom. The tilt sensor corrects for pointing up or down. • Width confirms: the width it sees has to fit the object too. If it doesn't, you're told why, for example part of it is hidden or the object type is wrong. • Ground check: up close, the angle down to where the object stands gives a third, independent reading. Every reading shows a 95% range and a High, Medium or Low confidence, so you always know how good it is. MEASURE WHAT YOU SEE • 124 ready-made objects: people (adult, man, woman, teenager, children, sitting, kneeling), 71 vehicles from bicycles to trains, ships and aircraft, and 45 animals from deer and horses to bears and birds • Add your own: enter the exact height of someone or something you know for the most accurate readings • Tap any detected object to lock on, and it stays locked as it moves • Manual mode: drag a frame around anything the AI doesn't recognise BUILT FOR THE FIELD • Zoom up to 8× with buttons or a pinch • Level indicator and automatic tilt correction • Red night mode that keeps your eyes adjusted to the dark • Torch for low light • Metres, feet or yards everywhere • Portrait and landscape MORE ACCURATE OVER TIME • One-minute calibration: measure someone of known height at a known distance once, and RangeFinder corrects for your iPhone's camera. SAVE YOUR READINGS • Save any reading with a photo, the object, the confidence and the zoom used • Browse your history and export it as a CSV file PRIVATE AND SIMPLE • No ads, no account, no sign-up • Works offline: detection runs entirely on your iPhone and the camera image never leaves it GOOD TO KNOW RangeFinder estimates distance from the camera image and the typical size of the object, so results depend on how close the real object is to that size, on light and on distance. It's made for hunting and wildlife scouting, golf, hiking, sailing, photography and everyday curiosity, not for situations where safety depends on an exact distance. For the best results, calibrate once and keep the whole object in view.
