So glad I found this app; proverbial needle in a haystack of overblown and overpriced measurement apps. It's simple, yet has a sleek look, and probably has more functionality than I even want or need! 🤣 I just want something at hand to get a gauge of things I see online: I'm a metric man and this really helps quickly and accurately see inches. And who doesn't always have their phone with them? Pro version is excellent value for money. 😁

I had been using the free version of this app for 6 years and loved it. I decided to upgrade finally and it is worth it. I like that I can now save measurements and measure in two directions at once. The "always on" feature is great too when you are studying the size of something for a few minutes.

It could be a perfect ruler app but I don't understand why the text with the measurment values is not visible all the time. It is a simple positioning and font color problem. Why you are not able to see the value of a lengh shorter than 12 cm? It seems a stupit option to make the text visible only when the nackground color is changing umder the text. Maybe you think for an update at least for the Pro version

I like it. I would appreciate it if we could get a diagonal line for measuring screen sizes. unfortunately the app did not adapt the screen size to my folding phone.
