Perfect
I've been using an HP 48 Calculator for years, until it died. This is exactly what I was looking for. It lets me enter all the numbers before I add/subtract them, to make sure I typed them in correctly. And you can stretch the size of the window larger so it looks good on my large monitor! I went and bought the iOS version so that I could pay you, even though I don't want to use it on my iPhone.
United StatesGreat Start
Very nice app, for the price. Missing some important manipulation funcitions (e.g. roll & drop) Additionally, 16C (programmer) functions would be a welcome additiion. Thank you.
United StatesSimple, fast, easy to use
My inital impression is that it’s a great app — does what I need, and doesn’t try to overwhelm you with useless features. If you grew up with RPN calculators, and don’t want to pay $10 for a HP emulator, this might be the perfect app for you. I plan on keeping it my dock for when I just need to do a quick calculation, and don’t want to wait for Excel to launch.
