    I had a 15c all through college in the 80s. This app IS that calculator.

    Just exactly what I needed. Works just like a 15c. You have to be a little bit more careful pushing the buttons because it doesn't have buttons. But otherwise I think it's great.

    So far so good. I'll edit this thus if I have problems.

    Still have my real 15C. On a MotoG4, this app is almost identical size. Yeah, the key fonts could be bigger. Switching to large font makes them equal, but it would be nice to have an app setting for that.
