Decimals not available in Inch format

Downloaded hoping to use inches to the 0.000 the app only calculates inches to the inch and fraction (1/16).
Makes this app useless to me without converting my data to MM then back to inches.
Developer-how about a decimal option for fractions?
Even programming was more complicated to only be useful for carpenters!

Response from developer

I will fix it soon

Very disappointing

Adds cover the top of app and you can’t change from fractions to decimal. Nice app terrible add placement.

Nice app

Straightforward does what he supposed to do

Response from developer

In the next update fractions will be added

A useful App, nicely presented

Update 01-Sep-2020 :

Thank you for the very civil response.
The App functions quite adequately with the Ads displayed but, as a matter of principle, I am upgrading at your new reduced price ... and I hope other users will follow my example, to encourage further development.

One feature I would like to see, if you can:
It would be helpful if the diagram changed to match the calculated results.

But the price to remove Ads seems a little excessive
