11C Scientific Calculator

★★★★★ Works great I have been using this app instead of my actual 11C calculator for quite some time now. It has worked great, no problems encountered.

★★★★★ Great apps! I bought 12c from Vicinno Soft a few years ago. It works perfectly and wins my trust as the company also provides excellent support service to customers. This app works exactly as HP 11c. It has excellent design and runs very smoothly. I am glad I bought it! Strongly recommend....

★★★★★ Love this app! I love RPN and the 11c and this is very close!

★★★★★ Just like my old hand held from grad school that costs more than $100.

★★☆☆☆ I still have my original HP RPN 11C calculator that I have used as an engineer for very many years. So I thought placing a 11C ap on my phone would be a great help, but the display is so small so as to render it useless. So unfortunately I cannot use it. Great idea but the final result is.....

★★☆☆☆ I've owned a real physical HP11c for 30 years or so. I love it. I love RPN. So I wanted to get this app for my Moto4+. It occasionally works, but more often than not, the screen jitters or shows PR ERROR. So the app is totally useless. If I can figure out how to get my $2.99 (+tax) back, I'll do that. But I intend to remove the app if I can't figure out how to get reliable results in the next couple of days. If I get it working, I'll edit this review and change my rating. I really want this to work. If somebody has a solution, I'll be ecstatic. I've uninstalled it.

★★☆☆☆ Hasn't kept up with Android I loaded this on my Nexus 6, it didn't size well to the screen. It still has the triple dots to access settings - it wouldn't let me access settings. I immediately opted for the refund.
