iPhone
Measure anything around you using your iPhone camera. Get accurate length, width, height, and distance from a photo — no tape measure needed.
Turn your camera into a tape measure. Snap a photo with a credit card or coin in the frame and the app scales the pixels to reveal the real length, height and size of almost anything.
No laser, no guesswork — just point, tap and read the measurement. Perfect for furniture, parcels, DIY projects, art, plants and anywhere a real tape is out of reach.
WHY THIS APP
• Measure length, height, width and object size straight from a photo
• Use a credit card, coin or A4 sheet as the scale reference — no calibration
• Read results in millimeters, centimeters or inches, converted instantly
• Drop several segments onto one photo to size many parts at once
• Save annotated photos to a history you can revisit any time
• Fully offline and on device — no account, no sign-in, no ads
HOW IT WORKS
1. Snap or load a photo with your reference object and the target both flat in the frame
2. Tap the two ends of the reference edge, then the two ends of your object
3. The app scales the pixels and shows the real-world measurement instantly
It's a fast, practical estimating aid. For fabrication or safety-critical work, confirm the result with a physical tape or caliper.
Full access is unlocked with a subscription — available weekly or yearly, or as a one-time lifetime purchase.
