I had the hp28s. This is a good replica
Pros: look and acts like the hp 28s. Cons: free version is too locked down to tell how well it works. I would have like to tried out other features, but that requires at least 1 upgrade possibly more. I could not tell for sure. I would pass on this one since I cannot tell how well it will work.

HP 28S Calculator Replica
Just like the last reviewer, I had a HP 28S since 1989. It bit the dust last year. This is an exact replica! If you do not understand (RPN - Reverse Polish Notation) you will be confused like Phat Dude. Take some time to learn RPN, you will find it straight forward and easy to use.

Love the HP 28S
I've used my HP 28S for three decades. I'm thrilled to find an app that emulates this classic scientific calculator. I haven't used the app much yet, but I'm looking forward to testing its features.
