Description

Touch Fin RPN is an RPN financial and scientific calculator that implements most features of the industry-standard HP-12C, including programming functions.

It also implements a scientific RPN flavor that implements most functions of the beloved 11C. And even more flavors (10C-like, 16C-like) can be purchased within the app.

Can’t have multiple calls open

I had the 11, 15 and 16. Opened one today and was told it was being “sunset” and I should get this one instead.

Once I opened my old ones, the new app worked fine with no ads. It it has one huge disadvantage. I use to keep the 16 and the 11 open at the same time. Now I have to switch modes. That is NOT an improvement.

Developer Response ,

The first-run of the new version showed a dialog explaining the migration process. You need to run the new app at least once on a device where the old paid app(s) were installed, in order to migrate your purchase. Then, press ON and choose the flavor without ads, that should be available without need of repurchasing.

The best HP as far as I’m concerned

As a longtime HP user, I own many of the physical calculators and even purchased HP’s official 15C app. That app is OK but had some usability issues that HP never addressed, and appears to be abandoned now.

When I tried the free version of Touch RPN, I knew I had a winner. The detailed rendering, keyboard feedback and vertical (portrait) layout are just what one would expect in a top of the line product. I purchased the Scientific Premium version and could not be happier. It was an easy decision to delete the HP app.

The negative reviews you see here are either critical of the all-in-one version vs separate app approach, or from people who don’t know what RPN is.

I have no concerns about the all-in-one version, but I do have a gripe. To say that an app supports Family Sharing when its only purchase option is via IAP is a flat-out scam, and this developer tarnishes its integrity by making such a claim. I wish Apple would put an end to this deceitful practice.

Versatile RPN Calculator — Well Designed

This is a well-designed, smoothly functioning, RPN calculator. I have not done a thorough test on accuracy but it appears to be accurate. Because the calculator is free, unobtrusive ads run in the upper right hand corner. Even the ads are well designed to be visible but not in the way. The designer has a flair.
