2025-01-06	CA*****	Where are the booleans with x and y? How can I edit equations as the HP27S? Where is the user manual? Added: I found out my self. It is very very easy to accidentally delete the ppar. I killed the cache and data in app. Now the EQN appears normally.

2025-01-01	Th*****	Purchased 2 months ago. Loving it especially the Matrix editor ❤️. Early days and there is much more that I have to discover now that I "upgraded" from Free 42. Excellent product well worth the asking price. Highly recommended 👍😎.

2024-04-03	fr*****	This improves an already excellent calculator. This app has been around in one form or another for maybe 30 years - It was then, and still is, the best calculator I've seen. My OG hp42 still sits next to the mouse pad, but this phone app sees more maths action. For the suggestion box: can we swipe from the shift button to the exit button to turn off (as opposed to tap shift + tap exit). Actually, swipe from shift to any key would be nice. Thanks Thomas

2024-02-24	Fr*****	It is an excellent calculator which takes the Free42 app and develops it further with additional features. I have no use for most of these additional features besides UNITS, yet I still bought the app to support the author in the development of Free42.

2024-01-24	St*****	This app is a fantastic RPN calculator, and the developer is very responsive to issues. I never owned an HP 42, but I do have an HP 45, HP 32S, HP 32Sii, and DM42. Guess I'm a calculator junkie. :-) Anyway, Plus42 is now my go-to smart phone calculator app because of its clean design and excellent features. Highly recommended.

2023-10-07	M.*****	I spent over $100 in 1988 for the original HP-42S and it was worth it! Now that I can spend $10 and get a more advanced version of the same thing on my phone is amazing. This is the best handheld calculator, in my opinion, ever! I've been using the Free42 version ever since it came out and now it is even better with the Plus42. The software by Thomas Okken is rock solid and well worth it!

2023-09-15	He*****	My only physical calculator that I owned was the HP35. The Free42 and Plus42 are wonderful walls down memory lane. I have the Plus42 on my Xiaomi Redmi Note 9 Pro where it fills up the whole screen and it feels even more like the real thing. Use it for everything, mainly for projects and domestic maths.
