There is no currency conversion in the app. I used to use the currency conversion, but I can't find it anymore. What happened?Please bring it back.

Up until recently, it's been really handy, but I mostly use it for cooking conversions. Now most of the time it's great, but the one thing I can't really do on it is converting meat from kg to oz. I think it'd make the app even better if you could get that on it.

This is the greatest converter so far for me. I've been struggling with newton meters and ounce inches etc for calculating angular torque. If your going to do physics in school get it. apparently it misses the cup to gallon etc conversions. This not so bad since most people are fairly familiar with these conversions anyway.

Was good. Now foes not even have currency convrrsion.

Not a bad app. Allows calculations & conversion in one, ads is a banner ad along the bottom 1/8 of screen so not too obtrusive however seems there no way to pay to remove it. Doing so would give more room for the rest of the app

It misses the most basics a cup=8 oz=1/2 pint, 2 pint = quart, 4 quart to a gallon ... No confidence, uninstalled.
