Customer Reviews

This review is solely for the Watch app...

... Seeing as I only use it on the Watch. The app is flawless. I thoroughly enjoy the usage of the hard press and I love the entire thing.

One problem: I need to be able to access the app in "glances". I use calculators on a daily basis and need quick access. At this point, it's quicker to pull out my phone and use the Apple-native calculator app than it is to go to the Watch home screen, zoom in enough to see the apps and click the Calcbot app. Update the Watch app with "glances" integration and you'll get 5-stars from me in a second.

The best is back!

Calcbot is my favorite calculator app. It keeps the simplicity I want and adds the little extras I desire. The tape feature is great. I really like enabling the currency option because most of my calculations involve money. Being able to easily convert units is icing on the cake.

This is a huge update to Calcbot and it shows. So much more than just a coat of paint.

Not happy

Had the old convertbot app and loved it. Well I had to get a new phone and when I restored it that app wouldn't transfer because they took it off the app store. Purchased this one for conversions and hate it. When you get to the conversion page you can't makechanges to the value being converted. You have to swipe right back to the calculator, change the value, then swipe back for the result. You have to do this everytime you want to change the value being converted. Why can't we change the value on the conversion page?
