Bit hard to calibrate, so not super accurate (still enough for most situations). It's nice that the pro version is separate application, so it doesn't annoy you with things you can't do without paying. Overall probably the best free ruler application.

Trying to attack your bank account. Every single time I tried to buy the Pro version, scammers attacking my bank account, and also calling me and trying to convince me that they are my Bank (from private hidden number) and asking me to confirm that device trying to access my bank account is ME!!!

Easy, clear, no fuss no muss inch /cm ruler. For things no bigger than your screen. You can, but it's awkward. The switch between metric and standard is instant. The choice of a light or dark background can be very helpful.
