Way better!

I like this app so much better than the one that comes installed on the phone. It keeps a history that I can search through later. I can even star/fav the ones I know I want to keep handy or notice I might need again. I can also slide to delete the ones I know I won’t be needing later. It’s great for all the functions I need everyday and so much more so I don’t have to worry when I need to do advanced calculations. I know I can do it all right from my iPhone or Pad so I don’t have to carry around a separate calculator in my bag. Yay me, now I have room for something else I might need :).

Just keeps getting worse.

It was bad enough when Tapbots decided to toss out all the beautiful designs they had for their apps in favor of the simple line drawn, childishly large numbered designs ( that just plain look horrible ) but now after using the app for years I do an update to Calcbot and now I can no longer use the Tape History feature without PURCHASING a premium for $1.99! Since I ten to trust developers not to screw users by removing function and holding them for ransom I didn’t fully read the update notes prior to doing the update so I don’t know if it was in them or not and I didn’t make a backup so I can’t revert back to the previous version so I have no option but to remove the app. To bad, Calcbot, Convertbot and Pastebot ( the last 2 not even available anymore ) used to be the GOLD STANDARD for app design and where the first apps I would show to friends to highlight how much better apps were on iPhones than other phones. Now I use Tapbots as an example of how bad app design has gotten over time, especially on the iPhone.

Limited Functionality

Used the old Convertbot since it was first released and it was, hands down, the best converter APP across all platforms. I work across multiple technical disciplines (aviation, engineering, programming and finance) and travel extensively. Calcbot is a poor substitute for Convertbot. Forget the interface, I can deal with that, but even after purchasing the Pro version of Calcbot, it only has a fraction of the conversions available in Calcbot with no way to select new units as in Convertbot.
Calcbot is but no more than average when compared to other converters and a serious disappointment to those who were used to Calcbot. I’d even be willing to pay a subscription fee if Calcbot were again made available. You guys had it nailed with Convertbot and took a giant step back with Calcbot.
