Became useless after a long time of flawless operation.

I’ve been using Calcbot for considerable amount of time. Purchased it before their was an option for pro. In the last year it has become painful to use. The problem is the delay when opening the app. It begins to pinwheel and freezes while it does I don’t know what. I’m usually going through quickly and when I have to wait 30 seconds about every other time I jump into the app before it’s usable, it becomes extremely frustrating. At times I just need a quick calculator, and Calcbot was my go to calculator. But it’s been such a pain and frustration that I had to leave a review. I don’t know what you guys did to a great simple and functioning app. But it’s broken, and a source of aggravation.

Agreed on limited functionality...

I have to agree with the other reviewer. Since meeting calc and convert, is not nearly as good. One practical annoyance is that the slider that gets you between calc and convert is hard to grab with the iPhone X inside an apple bumper case. It's hard to grab the edge of the screen... It's super annoying not being able to set your conversion values on one screen; you have to swipe back to the calc screen to enter them. Lastly, where's light conversion? Foot candles? Lumens? cd/m2?

Bought ConvertBot but now it's no longer available.

I bought this app when the Developers called it ConvertBot. I had to recently get a new iPod device and when trying to download my previous purchase, I found out it no longer exists. So I have to buy this app again?? No! The Pro version of this app does not appear to have all the same features as the previous version of the app. I will not buy the same app twice.
