    I think one only ever given a handful of five star reviews since the using the first UK Android device many years ago. This Dev team have implemented feedback suggestions quickly. No dodgy permissions, the app just does its thing without unnecessary feature bloat. Sure Vistech will go on to great things.

    I've browsed the ruler apps for a while and this one seemed to be the most useful one. Very functional options, easy to manage. I'm glad to buy you a quarter pint of beer guys :) Add1: The only remark would be that a manual setting area would be useful. Here the user could give the exact digit for the ruler by the keyboard manually. Recently I needed a 6 cm unit and it was a bit tricky to set it

    You can calibrate it neatly with a quarter and then never be caught without a ruler again.
