Pros and cons of Calcbot 2 app for iPhone and iPad

Calcbot 2 app good for

I never thought using a calculator could be fun. Thanks TapBots!
Great little calculator but what sold me was the integrated functionality of ConvertBot. One suggestion I have is to add the ability to sync conversion settings between devices using iCloud. Love that it already syncs the history tape but syncing settings would be even better! Keep up the great work!
I have been frustrated with the other calculators available for the iPad. This calculator is what I have been looking for. I upgraded to the pro version for a small price to unlock more features.
The built in calculator app feels so limited compared to this one it would be silly not to get it. Loving the pro features too! The only thing that could make it even better would be a simple conversion and calculation widget for the Notification Center. Thanks for the update, its really appreciated.
Love that you can swipe anywhere on the calculated value to switch to/from converter mode. Agree that RPN would be a nice pro feature (HP48-style preferably)
While app after app has exported features into new applications, Tapbots have seamlessly merged two wonderful apps into one!

Some bad moments

Calcbot was, for a very long time, the app I would suggest first for anyone I knew who got their first iPhone. It was my favorite app. It was a beautiful, smart, and well designed app, a must have. Ever since I got my iPhone 5, I was disappointed it was never redesigned to fit the bigger screen. I thought it was a dead app. I was even more disappointed when a update was released, but screen size remained the same. I still love the functionality of this calculator, but its the only non-iPhone 5 app I have
was the best / most used calculator - but no iPhone 5 screen at the end of 2013 - are you serious? More than a year later, with iPhone 6 / 6plus available, tapbots is not willing to upgrade their app. Instead they make a lot of buzz around the new calcbot for OS X - I can´t recommend a company with this kind of behavoir
Years of history gone. Would have been nice to know prior. I would not have updated.
Convention is not available in free version. If you are looking for a free convertor, dont waste your time. Its a free calculator with its own ads.
1 degree Celsius is 273.14 in Kelvins, not 274.15. Would be quite a considerable deviation in a chemical calculations. 1 star - just to catch attention, otherwise, well done!
I keep my phone on rotation lock because turning it sideways looks and feels stupid. Its clunky, its slow, and its the reason I used Calcbot over the standard iOS calculator. Now that youve removed that, I feel like I deserve my money back. What could you possibly offer me now that youre just a clone of iOS calc with a converter built in? All in all, I liked the old interface. The new one made me abandon your products.
