To use it I have to turn off Zoom from Settings. It would be nice if the app can detect the Zoomed mode and adjust accordingly or at least there’s an option the user can indicate the phone is in zoomed mode or not. ### 5/5 — Great tool in your pocket *2023-02-27, version 1.5.2* This is the first ruler app that actually does what it says it does, and without attempting to needlessly track data. Thanks, Dmitriy. If I need a larger version in my pocket, the paid version of this will be my first stop. ### 1/5 — Wrong measurements on iPad Pro 12.9” *2022-11-28, version 1.5.2* Wrong measurements on iPad Pro 12.9” ### 1/5 — very inaccurate *2022-10-25, version 1.5.2* 1 inch on the app measured to be 1.2 inches in real life. That’s a 20% error! Using iphone XS ### 5/5 — Make sure you’re not on zoom view *2022-09-13, version 1.5.2* Or your measurements will be off. Works as described. Still not sure why you would need a longer tape. ### 5/5 — Perfect *2022-09-01, version 1.5.2* This app is fantastic because it is so simple and useful. This tiny app does very little more than provide a precise inches / mm scale on the opposite edges of your phone. It turns your phone into a ruler. You set your phone against what you are measuring. The scale is accurate an easy to read. A uTube video shows how to get fancy with measuring things larger than your phone. They would like you to pay for a version that makes measurements over 17 inches. I don’t need that. I like that they don’t collect information and it doesn’t need to access your camera, etc. The only suggestion I would make to improve would be to add showing graduations on the top width. ### 1/5 — Does not work *2022-02-05, version 1.5.2* I did exactly what the directions say. Does not work. ### 5/5 — This looks amazing *2021-09-06, version 1.5.2* I will enhance this review after l have fully explored it but so far it is a totol win ## Frequently asked questions about Ruler Tape 17 lite ### What does the Ruler Tape 17 lite app do?
