Ruler - 統治者

很實用的app

I like this

like title

建議加上水平及垂直的的參考（水平儀功能），是否有正確切邊，另外不要太常問評分，會很煩。

Nice

1 cm shown my iPhone 6 screen is actually about 1.2 cm. Inaccuracy makes the creativity pointless.

The ruler in the screen is not accurate in iphone6s plus. The mismatch is about 1cm for about every 15cm

Good

Great but accuracy need improve!

The app is very useful. One note, results are visible during measuring. then they seem to be tied to the middle of the line. when measuring long distances, hard to find the final number. it would be helpful to see the result as a value somewhere on the screen independent of the measuring configuration.
