This was one of my most used app’s, right up until I got my new iPhone and it quit working. I’m not sure if it’s a hardware or software problem with the new phone; but I hope hope hope there is an update soon that gets this calculator up and running again.

This app works on my iPhone 7 but is broken on my iPhone X. Sad because I really liked it.

I’m hoping it’s just an update issue, but are you going to make it work on iPhone X? Paid the money, and it worked on on my 7+, but no longer.

The legendary RPN calculator for the iPhone. Some commented that it doesn’t work on new phones, but all I had to do was reinstall it on my iPhone X and it works perfectly. Some input delays that existed on my prior phone are no longer there either.

This app worked great for a while, then as others found out it quit Jan 2015. I have since moved on to Calc Pro HD because I would no longer longer trust upgrading to the paid version by this author.

Worked great at first, but suddenly started opening then immediately closing out. I really hope this gets fixed. This is identical to a calculator I own, and is so much more portable... Plus, it's much easier for me to use since I'm used to rpn.

Would love to use this excellent app for RPN calculator when the author fixes it! I would even pay for the pro version when it's operation is verified. Now it is useless since it will no longer launch as verified by so many negative reviews.

This the best calculator app for the iPhone, because it emulates the best calculator of all time. Also, now no longer crashing on startup in 2015. :-)
