"I have a 15C from 1984, an anniversary edition from 2011, and now this one. All work great! Now if Hewlett-Packard could only make their computers and software with the same high quality and robustness as their voyager series calculators..."

"Even better than the original, which I have still. Everything I have tried, including programming, works just as it should. But on my 7`` tablet it is bigger than ever before ! The emulation of the front of the device is truly well done, it looks like a photograph... wait, it may be a photo.... update: under 15c logo, first press brings up `settings` and I chose fix landscape, afterwards settings never reappears which is silly."

"I`m so happy!🤗 I have my beloved HP 15C on my phone! The one I bought in 1985 still works like new. This one on my phone just makes my day, even for $16.99, which is the most expensive app I`ve ever seen. I have complex technical engineering geology apps for $5.99. You`d probably sell a lot more if they were $5.99 or $2.99. Still love it! 😁"

"Installed on Oneplus 5 - A5000 - Android 9. In landscape view only the bottom of the numbers in the display are visible. So instead of 0.0000 you see u.uuuu. Need a refund"

"App stopped working when I got a new phone (Note 10). No numbers in the display area. Sent a message to HP and they ignored me. Here`s an idea. If you want to charge $15 for an app, sell one that works. Don`t ignore your users when your app stops working. You are a giant company. Fixing this would not burden your resources at all. Get your act together."

"This is not a complete HP 15C keyboard. I only has arithmatic functions. No geometric or higher functions. I do not recommend this app."

"For everyone having display issues, you just need to reset it. To reset, open the menu, where the power button normally is, and click on reset. It`s really as simple as that. GLHF."

"I can`t believe this is actually available... The HP 15c is my most favorite calculator which I`ve owned for over 30 years now, and always wishing to buy a brand new one, but not available. This app is FANTASTIC, THANK YOU HP!!!!! Please build the original HP 15c again!"

"Worked in 2019, worthless in 2020. HP failed again. If your Samsung 7 or forward, just play candy crush, that`ll work far better than my HP clicker."

"I`ve had the calculator since they came out last century. when I found the 15c in the app store years ago, I was so happy to have the same calculator everywhere I went. I`ve been using it for I don`t remember how long but it and it`s compadre 12c are the best ever. Thank you HP for giving us both of these essential tools and migrating them to our smartdicktraceypocketwatch."

"My 45 is defunct, my 35 too, but my 80s 15c still runs. This app is
funtastic. The orange is a little weird, should be yellow. The tips do
include the trig and polar diagram, the conversions, the sum functions, and
the program stack test diagram. They wore off the back of my real world
instance. It`s almost perfect. HP needs to add the spiral bound books as an
adjunct app."

"Works better than my original HP15C. I am not disappointed. It is worth it since the limited edition HP15C are not affordable."
