THE best conversion app available

I’ve used a ton of these apps and finally found Morpho around a year ago or so. I like it so much I became involved in beta testing as I want to do what I can to help the devs continue to build an excellent app. If you’re looking for a simple and visually wonderful app that’s as intuitive as they come get this one! It can convert pretty much anything you’ll ever need.

Converts everything in a super intuitive, quick, and streamlined interface. The only recommendation I could make is to include 00, and 000 buttons on the number pad.

OK, but could be improved

Works well in some ways, but could be better: 1) "clear" key on keyboard does not clear entry; 2) clicking on on-screen keypad works well, but direct entry of digits from physical keypad is somewhat confusing (no cursor entry point is shown on screen); 3) missing some functions readily available online for free (like teaspoon to grams conversion, etc., but teaspoon to ounces conversion is available).

Developer Response ,

Thanks for the feedback. 1) Right now you can press the "C" key to clear, but we'll look into using the "Clear" key as well (we went with "C" as lots of keyboards don't have "Clear"). 2) There is no a cursor entry point and it is now clearer as you type decimals as well. 3) teaspoon to grams is not offered because it is a volume to mass conversion that varies based on the item being measured. Volume to mass ingredient-based conversions are not in Morpho at this time.
