Simple. Simplicity means no crashing or need to restart the app. No app flood means it's not a hassle when one comes up - means less skipping and developer gets paid. How apps should be. It also means focusing on one specific task - as a result it does it well. I'll likely purchase this app, for those very reasons. Want an advanced app for measuring complex 3D shapes? Look elsewhere. Want a simple, fast, crash-free direct app for measuring small objects or spaces, look right here.

Close, but no cigar. I don't mind its simplicity, but I wanted accuracy. It's OK for crude measurement, but when I tried to calibrate, by aligning the 0 and 4" mark with a ruler, the 1, 2 and 3 inch markings were slightly, but noticeably, misaligned. The "calibrate" function seemed intuitive (finger-drag the ruler), but if my intuition was wrong, I could not find any guidance on the app. My generous 3-stars is only for those who don't care about precision. And, oh, the display is pretty.

An ok App. Says it'll convert mm/cm/in but there's no function to do so. it doesn't work as a measuring tape. Others are right when they say as long as you know the length of your phone it's about as helpful as that. Ads pop-up 2 often/quickly. I do like the toggle buttons for measuring items small enough to fit on screen. Graphics are nice/simple. Those that claim it works as advertised ought to kindly share how. Overall, it's okay for what it is.
