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 :).
Save your sanity
I really wanted to love this calculator... I really did. I gave it more than a fair shot and it let me down. The interface is beautiful and functional however, that is where the positivity towards this app stops. Loading times are stupid... why does a calculator have a 15 second loading time... really!? Also, there seems to be no other way to clear a calculation other than holding down the backspace button for an indeterminate amount of time. Ok ok... I can totally understand the whole holding down the backspace button to clear... the problem is that the app gives you no indication that the calculation has actually been cleared until you lift your finger off the button. Do you need to hold the button for 2 seconds? 5 seconds? Who knows. This causes a situation where clearing works consistently only half of the time. I don’t know... this calculator could be so much BETTER but it’s almost like the developers only did half their jobs on this one. Maybe laziness? Maybe someone got fired during development? Who knows... all I know is you should save your money ok this one folks. Many other better calculator apps out there. Personally, Solve is my go-to calculator app. You should definitely check out that app and leave this one in the dust.
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.
