RPN-15C

On a 5 inch screen becomes a 95% size (109mm wide) compared to the 1983 original that I own. Results are the same to the last digit for solve and integrate. But you cannot enter matrix elements, R0 and R1 don't change and does't show row and col!!! The only relevant visual difference is the size, shape and spacing of the keys and digits. While the original keys are squares 7x7 mm. the android ones are rectangular 6.5mm wide x 5mm high. Horizontal gap between keys is 3mm in the real one and 4 in the android.

I used this for a while on my nexus s, but it began to crash. Reinstalled and it worked for a while but then started crashing on opening. Now I installed it on a brand new Nexus 5 and it does the exact same thing. When it worked the app was excellent but it no longer works for me.

This is the only 15C emulator that actually emulates. Others attempt to replicate. The only thing that's preventing me from giving it 5 stars is that the graphics aren't enough to display on the Nexus 7 without looking very fuzzy.

Almost 10 bucks for a an app that won't work with a Galaxy phone...... I'd try to get my money back but my time is more valuable. They should pay me 100 for the tine lost....

The app is fantastic when it works. Have had to reinstall 3 times now when the app has not started or frozen on Galaxy 3. Have to carry my real 15c to meetings now.

Unfortunately I purchased the other 15c emulator on the market before this one. Compared to the other 15c emulator this one is much cleaner looking and has a horizontal and vertical layout option. Same price as the competitor but this app is far superior in my opinion.

Beautiful app. Works like a charm. I had this same app on my iPhone4S, but it's much better on the Nexus4 because of the bigger screen.

This is a nice rendering of the 15c interface. And a nice touch to add the back cover etchings. Good job. LG P690.

Great app.fot pocket calc. enthusiasts.
