more I love traveling with this app. It makes conversions SO fast. I love that I can select my most used and reorder them in a way that makes sense for me. It’s with the small yearly fee to go pro.

Using the app from the menu bar causes the app to crash frequently. Also switching back from negative units to positive is a bit convoluted. Instead of just being able to hit the - key again to toggle negatives off you specifically have to hit shift and = so that you send the sign to get it back to positive. If you delete out your input it doesn't show -0 so you won't know until the units are negative until after you start typing in your data. if the app didn't have crashing issues I would give it 4 stars but as it is the crashes make it hard to recommend.
Developer Response Sorry to hear you've been having crashes. We would really appreciate if you would get in touch with us at info@thinktapwork.com so we can troubleshoot. Thank you for the suggestion regarding positive/negative toggling and displaying -0. We have implemented those suggestions.

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.

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.
