Inaccurate

The ruler is inaccurate on my iPhone 6s Plus

One inch is not one inch

With this ruler, one inch is about 1.3". This is not helpful in my very precise world...
precision is my lifeprecision is my life

Thumbs down.

Totally inaccurate. Need to 'buy' different rulers. Gives very little instructions about how to use. Disappointing.

Not accurate

I have an iPhone 6s and the inches aren’t accurate. 2” in real life measures 1 3/4” on the phone. I thought I was going nuts trying to measure something...
