So here's my take on Plus42. I've tested a bunch of calculator apps and this one's definitely one of the more feature-packed ones I've seen. The amount of scientific functions and customization is pretty impressive. It's not the most user-friendly thing ever, but if you put in the time to learn it, it's really capable. Compared to the free HP-42S emulator it's based on, the added features like unit conversions and 2D plotting make it worth the small buy price in my opinion.

Description

Been playing Plus42 for a couple months now. It’s basically an advanced scientific calculator app with a ton of features. Pretty solid if you’re into this kind of thing.

Here’s what you can do – there’s the standard calculator functions, but it also does stuff like time value of money, unit conversions, and even 2D plotting. It’s got a bigger display than the original HP-42S it’s based on, which is nice. Took me a while to figure out all the features but they’re pretty useful once you get the hang of it.

Look, if you’re into productivity apps and need a really powerful calculator, you’ll probably like Plus42. It’s not perfect – the UI can be a bit clunky at times – but overall it does the job. Worth checking out for sure.
