droid48sx

Absolutely the best (most realistic) HP 48sx emulator I've found so far for Android 10 (soon to be Android 11–hopefully no issues after upgrade). _____ Only bug so far is that entering the same number repeatedly (0s for example) will register that the button has been pressed (tapped) with haptic feedback, but the number pressed doesn't always actually display on the calculator display itself. It's as if the key was never tapped, despite the haptic feedback saying it was. (Galaxy 10+)

I've been using my HP48SX since 1990, and this app has mostly taken its place. Everything is where it should be and having a backlit screen is great. It would be awesome if the developers could figure out how to emulate the add on modules, like the math and chemistry cards.

Great emulator, just what I have been looking for but couldn't find! Thanks. I am a veteran HP user so my experience may vary from those who are not familiar w HP calculators or RPN. Best of all, no ads. My only suggestion is to include a copy and paste operation to import and export a number from and to the clipboard

Really like this 48sx Calc. Been using RPN forever. The look and feel of this emulator is excellent. One question though... Where are the % functions? They should be under a 'real' directory. Did I miss something? You can get around without a % function but do like using it. Otherwise a great Calc.

Why emulate keys not registering on presses?! This is stupid. I have enabled haptic feedback, I feel the key is pressed, but the digit does not appear on the screen, like with the old hardware calculator with oxidated switches... Nice touch, but Why???

A few days ago the app became unusable. Screen of the virtual calculator is all black. Uninstall and reinstall solved the problem. I have Google Pixel XL, first generation, with Android 9, patch level August 2018, and security patches as of September 2018.

Excellent tool on my Samsung S7. But hangs for a long time after switching to S9. I read the description it states only supports to Android 6.x. If the author can cime up with an update that will be best.

I no longer need all the fancy features of a calculator like this, but since using an HP28s calculator back in the day during my college engineering classes, I really have loved the feature of working with RPN to manage a stack of numbers. This app is a great implementation of that calculator.

Running on a Galaxy S8 using Android 9. Fast and flawless. Like having a quick HP48s in my pocket. Thanks for keeping it updated for the latest devices and OS versions.

I still have a working 48sx that I use often. Probably almost 30 years old by now. No substitute for knowing where everything is. Very nice emulation.

I can tell this is a labor of love by a true HP calculator geek. It's been a long time since my HP 48 GX worked :(. I discovered this app last night, and I love it. Very realistic, it even "powers off."

Really like the app however it is now no longer functional. It immediately freezes now on initial input and fails to funtion. Using a Goggle Pixel 3

After 30 "dry" years in IT I'm doing a bit of woodworking. That's just what I need when doing some spontaneous trig stuff. RPN is a fast, no-fuss way of doing calculations. Love it!

I loved this app on my Galaxy S5. It became my favorite HP calculator and I depended on it for work. I now have a S10. The latest version of this app seems to have fixed all my issues with hangups. This a terrific app!

Memory and stack clear on exit. Good for basic uses, not advanced. Solve the save issue, and gains at least a 🌟...

Look exactly like my real HP 48sx. Just wish I had a way of dumping my Mechanical Engineering Pack Cartridge from my real 48sx into this! My 48sx is mint condition after 28 years! This app is the best one yet! Runs perfectly on my Samsung Note 9. Thank you sincerely!

Excellent app!!! 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 try this one. It's a keeper. Kudos!

Shows the stack which is handy. Not optimised for tablet so fonts not super defined. Works like it should which is what matters.

Had a HP 48 sx. Unfortunately the unit broke recently and was glad to see it was available as an app. My favorite calculator on my phone, what a bonus.

The best RPN calculator app I have used. Works flawlessly just like my old HP-48. No ads (thank you!) Just an excellent calculator.

Crashes all the time. Doesn't work even force stopping it. I'm uninstalling it.

Flawless perfection. This app feels like perfect code that does nothing but what is supposed to do. Thank you.

I love this app, was my go to for years but now it locks up. Fix freezing issue and i will rate 5 stars.

What a brilliant app and the fact that it looks and works like the original RPN calculator is just awesome 👍🙂 Great stuff👍

Best approximation of an HP-48G that I've seen in years of searching. I really wish RPN calculators were more common. I highly recommend this app!

This is the best emulator I have ever seen. I love having this at my fingertips wherever I am, and I don't need to go back to my desk to get my physical HP48G to do my math.

Looks good, but at least Solve does not work, probably not much works. Keep trying.

A fantastic HP 48sx emulator. I love this calculator but it sits in my desk now this is much better for on the go.

My HP 48DX stopped working years ago. Amazing that I still remember how to use it. Like an old friend.
