Mathematics with PocketCAS Pro

This app is amazing, really. I own HP48, HP50, and HP Prime. While the Prime can do most of what PocketCas can do, it just is so much simpler in this app. I’m no mathematician but I’m able to solve equations and compute derivatives and graph multiple equations at the same time and it’s just so easy. Bernard Parisse is a genius!

I own both a TI-89 and a HP50G and despite owning ton of apps for mathematics, this is the first one that's able to replace them (either one of them). The interface is great and I'm already familiar with the CAS-engine "giac". Giac is the successor to HPCAS or erable for the HP48, also the engine of HP's latest calculator Prime.

Helt enkelt den bästa appen man kan tänka sig! Den gör taylorutvecklingar och kan gaussa. Vad mer behöver man?

Like this tool. So simple to use but still powerful. Easy to export makes it so useful.

Easy to learn and give you both an exact and a numerical value

Välgjord och enkel att använda. Ingenjörens "måste ha"-app!

I use an HP Prime Graphing Calculator and this app is the best alternative, or maybe even an upgrade, for its CAS function. They use the same kernel known as Xcas. Though HP provides a completely free emulator for computers (25 bucks for iOS), it's frustrating to navigate through formulas in an 'exactly emulated' window with a 320*240 resolution. Besides, I'm happy to find this app supports more 3D graphing functionalities than HP Prime. Such as 3D parametric plots, lines, planes... and even animated plots! I've also tried the app from Xcas website, only finding it's not updated and maintained for newer macOS versions for a long time. And to be honest, the original Xcas app is really hard to use. An added bonus is that this app supports the Handoff function. It conveniently pops up on the dock of my Mac, and with just one click, I can seamlessly transition it onto my big screen. Don't hesitate to get it! Totally worth the 50 bucks for all your Apple devices!

This is a very good program. XCas/GIAC on the ipad! The GIAC kernel looked up-to-date (9/2023), so the dev appear to be keeping it current. The 900 or so page manual written by the GIAC developers(?) Is excellent. The only problems i have had involve file I/O but that is because of the protected nature of ios sandboxing, not this program. There are ways to read and write files from the menus. I highly recommend it.

After the latest update, this app no longer runs on iOS 12.5. If the Devs don't want to support this version of iOS anymore, that's fine, but please don't push an update to my phone that no longer works on it!

Great calculus app. Use it all the time as well as in classroom (DSP). Now retired from teaching but still use it. The latest version on iPadPro 2 doesn't allow adding or editing your variables. Can still declare them inline as usual, but the handy feature when dealing with a set of similar graphs is greatly missed. Still a great app.
