Mathu 12d Financial Calculator App Reviews

Great app. It works great. I've used Creative Creek apps for years. Just wish I could change the colors so the calc more closely resembles the HP-11 or 12. I don't like the olive green keys!

My overall rating for the app is 5 stars, but my rating for the current version is 1! Please come out with an update to bring back full screen on the iPad. I would even pay again just to get the old version back!

Just get it!!!! Great price and it is exactly like the hp12c....

Perfect smartphone version of trusty HP12C. If you love your HP12C you need this app.

Word perfectly but keys are cramped. A simple iPhone 5 update would solve that.

Best 2 bucks I have spent in a while.

So great that they created this with some additional functionality. It disappeared from my iPhone after an iOS update, and I missed it almost as much as if I'd lost my phone entirely.

Just like my HP-12C, but faster. It makes my old calculator seem so slow in comparison. I love the two line display, the always available financial registers and the quick results. If you are an old HP-12C user, you will love this app. You could buy a free version, but why? You get what you pay for, and this is definitely worth it.

This is the one! Just like the original ( and I've had an hp12c since 1980). Great value. Thanks!

Reviewed all the free & expensive reproductions. Tried the free calcs; defects galore. This has landscape view, key separation for my fat fingers, fast response. Having owned an HP-12C, I found myself instinctively moving over the key set. Few errors.

Screen too small on iPad !!!!!! In new version

iPhone XR - app works , but once you start it , you are stuck on the app until you do a restart. Keeping 5 stars for now since the performance over the last 5 plus years has been perfect until now.

I've been using the HP12C since the mid-80's. It's the best, and I can't stand regular non-RPN calculators since then. This app was worth every penny. Now I have my "12C" everywhere I go.

I have used the 12c since it was first sold by HP. I used its predecessor model, too. I use HP's virtual version on my laptop. This app is a seamless improvement on a classic design. Take this from a retired financier, this is the best financial calculator app! Update: Still using it with iOS 10.

Need Update for iphone 5

The graphics are HORRIBLE

I've used a number of Creative Creek RPN calculator applications, going back to my Palm OS days. They have always been robust, accurate and well supported. So far the same is true for MathU 12c. Also, the on-line documentation is very good.

This is the best hp12c Can u make a version for he iPad ?

Have been using a conventional 12C for decades only complaint has been speed. This IPhone/Ipod app is great. Very quick and functions exactly like the 12C so if you are an experienced 12C user there is no learning curve. Would highly recommend.

Used the HP 12C for years as a real estate broker. This app is like having my old HP12C back again, only better.

I too have been using a 12C since it first came on the market 35+ years ago - Yikes! - But wanting not to carry an actual 12C around I discovers this WONDERFUL App 4 years ago! Its always worked PERFECTLY! No need to buy the “competition” - this free app does the job!!!! Thanks!!!
