Simple, powerful, familiar

I normally use the calculator app that’s preinstalled on my phone, but its super bland and doesn't have most of the features that I want when doing simple but a bit more complicated problems. And this app solves the problem. It looks a lot like iOS’s calculator app, but it has history, parenthesis and many other features with a nice looking interface and smooth animations. You would be happy to use it, and even more if you have an iPad.

Paid upgrade unit conversion is unintuitive and laborious

I paid the upgrade fee for the conversion functionality and I regret it. It is very awkward to do conversions as you just cannot select two units to convert between easily and quickly. You have to go into a menu and and create a conversion group first and then use that to convert units. It’s an awkward process that takes too long. After you have created a conversion group you can use it without having to go through a menu by tapping on an icon for the group you made, which is good for conversions you do often, but every unit conversion of the same type (ie. mass) uses the same icon and there are no text labels to show which is which. You have to tap through each one to see what it is. You also cannot just tap an icon to switch back and forth between the units, you have to tap one one to pop up a menu and then change it. The whole process is tedious and you’re better off just using any search engine or some other app to do the conversion, especially if isn’t a conversion you will be doing over and over.

Developer Response ,

You can add more than two units in one group to avoid creating multiple groups of the same category. You can edit groups to add/remove units when needed.

I'll try to make switching the source unit easier.

Shows Extreme promise on mac, however...

It looke like this was released just a few weeks ago for mac, so I did not want to ding with a low star rating...Program would not load first or second time I tried to open the app on mac. The Clear button does not work either from the app or clear histor from the menu bar. If you will fix the above items and make it so I can resize the app, I will purchase pro. :-)

Developer Response ,

Thanks for reporting this and helping solve the problem! The new version fixes issues related to clearing. The launch issue seems to be related to macOS 14, which is becoming less frequent starting 14.4.
