  H AL: Perfect apk!!! It works flawlessly... OK it hangs every now & then but not more than my physical HP calculator XD If you feel homesick of the HP calcs era, or need a serious engineering calculator, you gotta test this one. It's a keeper. Kudos!

  Renan Paglin: Good emulator, just what I have been looking for but couldn't search! Thanks. I am a veteran HP player so my experience may vary from those who are not familiar w HP calculators or RPN. Best of all, no advertisements. My only recommendation is to contain a copy and paste operation to import and export a number from and to the clipboard

  Mark Farmer: Had a HP 48 sx. Unfortunately the unit broke recently and was glad to see it was accessible as an apk. My favorite calculator on my smartphone, what a premium.

  Volker Hetzer: After 30 "dry" years in IT I'm doing a bit of woodworking. That's just what I need when doing some spontaneous trig items. RPN is a quick, no-fuss method of doing calculations. Love it!

  Alex Camprubi: I liked the skin of the Droid 48... but the functionality was giving me a headache.... stopped all the time. This Droid 48sx's functionality is unbelievable, but I miss the skin of the Droid 48.... and the feeling of the vibration in the key. Thanks for giving us a good HP 48....

  Darius Revel: RPN is various, but once learned you'll never wish to go back. This apk is just what's required at the right price.

  Tru Tran: If you are a fanatic of HP-48sx calculator then this apk is as close to the true calculator as it can receive. The icing on the cake is all your tools written for this device will now run almost instantly.

  Greg Harrison: It's good, I've programmed it already. One recommendation; I hold tapping the screen while touching the tool selectable buttons at the top. How about extending the selection region for the soft keys to contain a tiny bit of the display? Then it would behave a tiny more like a touch screen, and touching the soft key title would no longer cause the menu to come up. This is an good product. I'm going to love to use it. Thanks.

  George Pandzik: Best approximation of an HP-48G that I've seen in years of searching. I really want RPN calculators were more common. I highly suggest this apk!

  Stew S: I love this apk. Thank you. One thing is it seems to lock up on a nexus5x 6.0.1 after a bit of use. Have to reboot the apk. You mention you have not inspected on a 5x but if you receive a possibility please fix the lock up. Thanks once more.

  Matthias Svoboda: Thanks! Almost brought a tear to my eyes ;-) Still the best calculator ever, and the lack of haptic feedback compared to the original hardware is somewhat compensated for by the speed of a modern phone.

  Carlos Wilson: An perfect gratis HP48SX emulator. The memory is expandable from settings which emulates 128k RAM cards. Furthermore the memory can be protected by the save checkpoint option. If the calculator crashes or otherwise locks up simply use restore checkpoint. Save and restore checkpoint ought to have been on the original! Perfect on multiuser devices. All apk data is kept in the user's Android/data/ directory. No interference from other player. A lot of apks shop part of their data in /data/data/ which is a device wide place. This one does not do that.

  Richard Smith: Been using this apk for a few years. However lately it has been freezing more often than not. Currently unusable. Sadly, I think the developer has moved on.
