User reviews

Please fix font contrast!

This app is exactly what I was looking for.

BUT...

It's impossible to read the measurements!

The sample images in the app store use a normal easy-to-read black font for all results.

In the app on my iPhone, all results are in white font on the pale light blue-gray background. Impossible to read.

Please change the font contrast, or provide a setting for users to choose.
