I tried 4 times to install this app on my samsung galaxy 3 and it would not install

T70%
by T####:

Response time is much too slow

W70%
by W####:

Perfect simulation of the original, but now so much faster. Some people seem to have marked the app down for idiosyncrasies of the calculator rather than the app, which I think is a bit unfair - a good simulator should be a copy "warts and all".

I have it on all my Android devices

G70%

UI is superior to Pascal's TI-59 Emulator! Haven't tried any Library Modules yet.

P70%
by P####:

It made programming easy and bested the HP calculators of its time. I was one of the first to buy this machine and still have it in great condition except that the card reader needs re-conditioning. Thanks to Lawrence D'Oliveiro for bringing the joy of programming this machine back into my life.

My favorite Calc. I had one of these in the early 80s. With magnetic cards. I have a problem with the latest release. I don't have any more the library of programs. Can somebody help me on this? Thanks

This app brings back the good memories . I have used my TI59 in college some 35 years ago and still have it in one of the drawers. I noticed two issues in my Samsung S6, 1. When touching the display location of the calculator, a message comes up saying "Sorry, no help available for this program" and does not disappear no matter what I do. Second (2.) Issue is the soft menu button always comes up on the keys. If there a way to fix it just below display location or have the user able to select the location.

Truly great. If you ever had one you know how great they are. It also holds its own against a modern hand calculator.

A70%

I would love to see more programming modules. This is awesome. I had this calculator back in college and actually went through several chargers and battery packs for it.

Z70%

I have nostalgia over load looking at this. :3

W70%
by W####:

Thank you for this excellent app. I used TI59 ca 40 y ago and surprisingly, I installed this app and susceeded to program at once. The simulation is very accurate. Also the appearance is like the original. Very good job. Thanks again for this free app.

03AUG2013 I love this APP. Reminds me of my first TI-30 which I think I got in High School around 1979. Doc Claridge (R.I.P.) our science teacher for two years, Physical Science and Chemistry, would not allow us to use calculators in class. We used slide rulers to calculate outputs of chemical reactions using quadratic equations as I recall.

helps Me do all the work I need

U70%
by U####:

I still have my ti59 and the printer. The print head no longer works but it makes a good desk unit. I also have most of the ti59 newsletters (with all of tips and tricks). If you would like a copy of them let me know.

I70%
by I####:

Crashed within 2 mins. I had to restart note3. To get out of app.

T70%
by T####:

A lot of errors the prg 20 master library

L70%
by L####:

Needs work. First thing I do on any calc is test divide by 0. Fail here, no error msg, just 0. Clicking key sounds are obnoxious and no apparent way to silence. On Nexus 7, app grabs whole screen and only uses 50%. At least make it float. All that in one minute test. There is promise here, but not ready for prime time. I'm shooting for the moon, not cosmic debris.

S70%
by S####:

There's currently no indication as to whether 2nd function is engaged; it would be helpful if the display had a "2nd" symbol for when it is in use. I also think it would be more user friendly if the calculator filled the whole screen.

G70%
by G####:

It has a real engineering mode: 100x100 = 10e3.

Q70%
by Q####:

It's really good but how do I get to the integral and differential buttons? It's screen is small I expected to see a large screen to see steps to the answers too.

B70%
by B####:

Needs old library modules available also. Otherwise a very good emulator.
