The app divides an inch into 10 segments. Ordinarily inches are divided into either 4, 8 or 16 segments in the imperial measurement system. ### 5/5 — Clever *2023-01-16, version 1.4* For measurements of things that are shorter than your phone this app is very accurate. But the clever thing about the app is that you can measure longer things by putting your finger on the screen and sliding the phone while not moving your finger. The accuracy of the result will depend on how steady you can keep your finger, so if you need absolute accuracy you’ll still need a tape measure, but this is a good way of getting an approximation. ### 5/5 — Very useful *2022-09-08, version 1.4* Very handy tool ### 5/5 — Measuring tape *2022-06-15, version 1.4* Thank you for a accurate measuring tape ### 4/5 — Great feature *2019-05-10, version 1.1* Great. No longer will TSA or Event staff confiscate my tape measure. ### 1/5 — Delete for Me *2019-04-10* Delete for me. Adds pop up constantly. Couldn’t get the ruler to swap from left to right / right to left to measure opposite direction. Sorry. ### 1/5 — Deleted immediately *2019-04-07, version 1.1* The ticks for the inches are just scaled up from cm side so they’re in 1/10th increments. Reads nothing like a typical tape measure. ### 1/5 — Pointless *2019-04-06, version 1.1* Difficult to understand what the point of this is. ### 2/5 — Go the extra step please *2019-04-06, version 1.1* Instead of assume normal people know what the diagonal dimension is of their phone and ask them to enter it as the first thing they do, why don’t you detect the phone model and do it automatically? It seems like meeting someone for the first time and you go straight to “how old are you?” ### 1/5 — Full page ads = DELETE *2019-04-05, version 1.1* Don’t waste your time on this app. Plenty of truly ad free apps out there that functions as rulers. ## Frequently asked questions about Unlimited ### What does the Unlimited-Length Visual Ruler app do?
