I'm stoked on this app. No ad's taking up space, its accuracy matches to my ruler, if not you can calibrate it with a few different methods. You have the option to slide the ruler guides up and down or left to right and it logs them so you can reopen on the ruler. Only one thing I would like to see is an option too maybe + × ÷ -. I thought the history side bar at first was giving me that option but it wasn't. So I think that would be a great addition. Otherwise 5☆, I for sure bought you a 🍺.

I downloaded the free version about a year ago, because I needed it for only (I thought) one time. I never realized how many times I actually need to pull out a ruler or tape to measure stuff. Now I use it all the time! I upgraded to the "buy the developer a beer" version as a thanks for a very simple, yet everyday useful tool.

To the developer: Beers must be cheap in France! Love the lack of ads, the straightforward, simple and accurate interface and your refusal to data-mine with unnecessary permissions. I didn't need to pay but I wanted to. I'd buy you a whiskey if I could have!
