This is an excellent TI/AOS calculator with the EE & ENG, and 1/x keys that I am so used to. My 3/5 stars have to do with usability. There is a loud and annoying keypress sound that I can't find a way to disable. The double line font is hard to read - solid would be better. And for those of us with low color vision, changing the red-on-black numeric display to a higher contrast combo would be helpful (although this is true to product). Love it but hard for an old geezer to use.

Provides a good simulation/emulation of the TI-58/59, without being an exact replacement for it: the app has a few additional features, and occasionally programs developed on the calculator won't run correctly in the app. I've used the app frequently over the past two years and its behavior has changed recently. It now forgets stored data, program, and settings between sessions. Otherwise, it's a great app, and I hope that the recent issues with it can be fixed soon.

This app is fantastic! I was fortunate to have the TI-59 calculator back in the late 70s while studying at university. It was my pride and joy, and taught me programming, which later gave me my career. I also had the good fortune to be able to publish a few computer games I had devised for it (using the text readout of the print cradle) in a magazine at the time. Very useful funds for a student! If anyone is interested in such ancient history, I may re-publish some of these.
