User Reviews and Ratings
★★★★★ Cleanest and most capableThis app is definitely the cleanest looking advanced calculator app I’ve been able to find on the app store, after looking over a huge number of them. It’s also very powerful, featuring plotting, solving and conversion, all in a clean and uncluttered way. This is a calculator app with a lot of attention to detail. The dev is responsive to feature requests too!
★★★★★ Brilliant app, and responsive DeveloperI’ve used this app for a year, and when I found a operation listed as undefined that shouldn’t have been, Jacob had fixed it within TWO DAYS!! I couldn’t have asked for more. I highly recommend the app, it’s the best calculator I’ve found, especially for keeping open while taking notes, or doing homework on your iPad.
★★★☆☆ It’s nice … when I can find itThe app is nice enough but it’s not findable on MacOS. So it’s running on my computer but I can’t see it. I also can’t force quit it, so essentially the only thing to do is to restart the computer, which isn’t happening. I’m sure it’s a simple bug and look forward to the developer fixing it because it makes the app unusable most of the time.
★★★★★ Love it!By far the best calculator app I’ve ever seen on the iPhone. Nothing else comes close to how versatile and powerful this app is.
★★★★★ Feature rich calculatorThis is a nice alternative to the stock calculator. Its’ Apple silicon code runs on iPads, Macs and iPhones (just noting that the developer allows this and doesn’t try and sell 2 versions). A little more interface customizing and it will be great!
