Almost perfect. It's possible to give the option to keep the screen ON?.
Best HP I ever had, now on my phone, what else do I want......
I have bought this app in the past, thrn put of nowhere I am with this free version filled with adds. I've reported that I bought it in the past and today, with the app support, I understood the issue with the previous app. I might buy it again because its the best way to use the calculator without walking with an actual one.
Best free 12C emulator. Non-intrusive ads and the backspace helps A LOT.
Careful with this seller. He decided to remove the previous premium version, which I bought and re-add it to Google Play under a different name (Same app I believe) to get people to buy it again.
