Calipers lets you take measurements when you're on the go. For the big things, there's 5 meter tape measure. Simply place your iPhone on a surface so the ‘zero’ aligns with where you want to start your measurement. Next, place a finger near the bottom of your iPhone and slide your iPhone along the surface, keeping your finger still. Finally, when your finger reaches the top, repeat the process again until you’ve completed your measurement For the little things, the calipers mode will let you measure objects within a tenth of a millimeter. Simply place an object on the screen, and drag the top and bottom guides until they are just visible. To get really accurate readings, you can use the ‘plus’ and ‘minus’ buttons to move the guides closer or further apart by a 1/10th of a millimeter. 6 out of the top 10 free apps in this category are off by as much as 10% on the iPhone 12 & 13 Mini, or when some accessibility features are enabled. Since most people don't check their app against a ruler - we felt it was really important we did! This app has been throughly tested to ensure the measurements are accurate in every scenario. ## Key features - 5-meter tape measure - Precision caliper mode - Measure to 0.1mm accuracy - Spirit level functionality - Accurate measurement testing ## Recent user reviews (10 of 18) All indexed reviews: https://appshunter.io/ios/app/calipers-tape-measure/id6445826923/reviews.md ### 5/5 — So good in a pinch. *2025-05-29* Being able to measure small things quickly with this app is incredibly nice. Can’t say how accurate it is but when you just need a quick or visual reading, it’s great. ### 5/5 — Accurate *2024-12-28* More accurate than the AR measure app, this app deserves more love **Developer response:** ❤️ ### 1/5 — Garbage! *2024-06-10* Nonfunctional piece of garbage. If I had paid more, I would be very mad. **Developer response:** Sorry to hear it hasn’t lived up to your expectations. What issues are you having exactly? There’s a contact developer button in the app - I’m great at getting back to people 😄 ### 5/5 — Works! *2024-06-10* It works as advertised. **Developer response:** Thank you 🤩 ### 5/5 — Simple but useful *2024-03-11* Very simple but useful app. The native measure app is good for approximations of large areas but I have much more confidence in the accuracy of this app for the finer details **Developer response:** ❤️ ### 3/5 — So close *2023-12-31* Using the micrometer (right icon in segment control), the app locks up when touching the zoom control. Everything else looks great, wish it didn’t have this bug iPhone 15 pro max **Developer response:** Sorry for this! I put out an update to fix this yesterday.
