Works exactly as advertised - an essentially perfect emulation of the 50 year old HP45. I use it for the nostalgic computation experience (the original replaced my slide rule in physics classes - I spent the small fortune of $395.00 to purchase directly from HP), and it does that perfectly.

This is a retro item that one would buy mainly for the feeling. I purchased HP 35, the first ever scientific calculator that I was gifted by my dad in my first year at university, in the Apple store. It's the exact image of the original unit and gives me immense pleasure to look at it, not to mention to use it. This app is simply missing the gist of it. Too bad and disappointing. The upside is that you are allowed to get a refund if you are not happy.

Great app. Works fine on my LG G7 Thinq running Android 9. 4 years later, worked fine on my galaxy s20, galaxy flip 4 and now galaxy flip 6. I have never found any flaws. I purchased an hp45 in 1973, still use that calculator as well.
