WAS a great app... Now it SUCKS!! Start entering your numbers and then... without warning, the screen adds a stupid ad at the bottom of the page pushing every button upwards. It does this right as you get ready to tap the "Equal =" key, thus forcing you to click on the stupid ad!! Accident ?? I think not. I even contacted the owner and described the issue, yet he refused to fix it. I guess he is more interested in getting a little kick back from the stupid ad he forces you to click on!! There has to be something better out there!! NOT worth the time!!

You can simply wait for the ad to load before you begin working. The "little kickback" from the ad is the little amount of money we make to produce apps for people who don't want to pay for apps. If you dislike ads then simply buy our paid version that has no ads.

This COULD be such a great app!! Constant stupid annoying ads that move the screen while trying to work. Thinks it always knows best... IF I subtract "inches" FROM "inches"... I want a answer IN INCHES! No longer works after last stupid update. Stop fixing what ain't broke!!

There are no instructions on how to enter a fraction. The help button lead to a YouTube video on the settings, which is nice. But zero explanation on how your buttons work, or how to do a basic conversion. BUT, on the plus side, I have hopes that your app can do what the other calculators can't seem to do: Be useful. I just want to convert between Imperial with fractions, to Metric with decimals. Like a simple measuring tape.
