I used this for years and loved it, even though it was always a bit buggy. The latest release forces a title bar at the top of the image that messes up the calculators proportions and makes it hard to use.
If you miss your old HP16c, you'll love this app. You can't replicate the feel of the physical buttons, but all the functionality is there, plus the convenience of being on the phone I always carry anyway.
An RPN calculator is a must have for me, calculations are much faster to enter and it's what I have always used. I am still using the 11c I purchased when I went to college and this app is very convenient to have on my phone at the ready.
Thought it was broken since numbers didn't display when you typed - on my Samsung A31 under Android 10. UPDATE: Turns out the calculator is working - you just cannot see anything in the display if you have Android dark mode on.
The last version was functional but didn't work quite right on unusual aspect ratio screens. This version mauled it.
I type, the keys sound, but nothing appears on the display. I can't use it!
Nice handy 16c emulator. Replaces my 16c i bought in 1982, which still works.
Beautiful, thanks for that last update!
Keyboard is so blurry it's barely readable. Sloppy work. Needs to be redone properly.
I scrapped a stack of my own specialist programs a year or so ago! Now I'm crying long tears. Please improve the text resolution on the keyboard layout.
Graphic quality is really bad. I can't read the blue text.
Still have the original but rather use this app on my phone. Great job
The rendering of the "calculator" is very fuzzy and hard to look at. Fix that and I'll reconsider my rating.
I still have my HP 16C (and 15C) and this app. is the best emulation. Even installed the Windows version.
As a HP user from the 1970s it a pretty good emulation
I have a real HP16C which I bought new back in 1980 something. It still works great, but app has taken over to prevent more wear and tear on the old HP. Nice job!
Great emulation of a classic calculator. This returns the classic RPN calculator you can use with both thumbs.
This is a nice piece of work. The graphics on my Samsung a3 are fuzzy though and when entering a simple program (enter , 2, X) the calculator just says "running" permanently. Since I actually have a voyager style programmable, I know this should work.
I still use my 30+ years-old 16c. Could use a better bitmap, but this one's functionally perfect. Worth paying for.
I love this application. Work precisely as expected. Great job.
Nice app, similar to my own hp16c. Also have this on my PC.
Hard to read display
Great emulation. Small footprint.
But needs some work: Screen is fuzzy. Display half invisible and scrolls. Uses old (Android 2) GUI design.
Sadly it didn't seem to work quite right for me. I couldn't get from hex mode to normal floating point mode using gold float as I would on my wife's original 16c.
My beloved HP16 was stolen. This app helps me to go on.
On my Motorola G8 Power (Android 10) the right-hand side of the numeric display is "missing". So the first ~4 characters (in dec/hex/oct/bin mode) can't be seen. It was OK on an older Motorola phone (Android 6). A pity, as it makes it unusable. 11 June 2021 - I tried the update (and phone is now on Android 11). This has a more severe problem. Input no longer works. The keys icons all "move" a little, but no numbers appear at all. 17 June 2021. Latest update now working OK. Only "complaint" is the ON button doesn't do anything. If it worked as ON/OFF it would be a quick way to clear the registers and display.
