I used to love this app and use it all the time on my iPhone 6. For some inexplicable reason it has become super laggy to the point of being very frustrating and unusable. I tried deleting and reinstalling it which helped for awhile, but it soon began lagging again. It still works fine on my iPad Mini though. Seems like perhaps it's due for a maintenance update of some sort.

Convertbot was intuitive and valuable. This replacement makes my life much more tedious. I would have paid two bucks for Convertbot, since you've decided you need a revenue stream. For Calcbot Pro? No way. I'm going to use this only until I can find something better.

The interface takes everything that made Convertbot easy and simple to use .... And throws it away. Highly disappointed and would not recommend this to anyone.

Calcbot (in all of its iterations) has been my calculator of choice for years, most often used for 1) depositing multiple checks at the bank drive-thru, and 2) tallying scores for my wife's Irish dance competitions. In both cases, it performs admirably, especially thanks to the history tape that lets me double-check my work at a glance. The unit conversion feature (requires $2 Pro upgrade) works very nicely too, with tons more options than I'll ever need—although the choice to have users switch back to the calculator screen to change the numeric figure and then switch back again feels odd. I can see why they did it that way, though. Doesn't hamper my love for the app at all.

Originally purchased the 1.1 version of Calcbot pro and was satisfied. It was updated to the 2.0 "free" version with less features. Talbots said I needed to upgrade to pro, again. App deleted.
