nearly perfect! I love this calculator! It reminds me when I was a student (my math teacher had a ti58c, I couldn't afford it!). I'm wondering if also the other libraries will be implemented/completed sooner or later or not. PS: in the meantime I tried to add some modules to the orignal library, I started with ML-02 (DETERMINANT, MATRIx. & SIMUL EQ) as I found the source code. Unluckily the emulator could have a bug as it doesn't work.

Gregory West

Great program, no instructions I am not talking instructions for using the TI-59, but instictions like installing modules, creating mag cards etc. A site for help and hints on using the App.

Love this but... I love this calculator and sincerely appreciate the effort that went in to it. It brings back lots of memories! This last update though doesn't fill my nexus 7 screen like the previous version did. I hope we can get that back. Thanks!

Nice Emulator. Very faithful to the original! Lawrence, if you're open to some simple suggestions, then consider breaking "true" emulation and make small concessions to the display. Back in the 70's the LED display technology was a huge limitation and some things that really should have been displayed were omitted. (1) A small status line to display things such as the current "2nd" and "INV" state, as well "Deg/Rad/Grad" would be incredibly useful. (2) In program mode a simple 3 character mnemonic (like "log" or "SUM" etc) could be appended to the numerical op-codes. This would greatly simplify program editing. Some purists might object to any departure from the original display, but it could be as an option.

Coolest app ever. This is NOT my favorite calculator. It IS my favorite app. (It's my 2nd favorite calc.) For a good calculator, and to answer everyone's reservations about this, get the "RealCalc" app. It does what you want. But THIS app, does even more. It's an almost perfect emulation of the Ti-58 programmable calculator. And that's what makes it so special. I can't believe how much work the author put into recreating this wondrous old machine. Here's my deal . . . I have to level some sophisticated avionics systems. I have an ultra-sensitive electronic level that reads out in tenths of a milliradian. I have to insert a shim that corrects for that deviation. So, I have a right-angle triangle with an adjacent of several inches, and an opposite of maybe .0005". Try plugging those numbers into any "triangle" app. Those apps are made for "high-school" shop class trigonomics. This app solved my problem. With a few simple "learning" key strokes, I entered a somewhat complex formula, and could convert a number that was tenths of a milliradian, directly to an appropriate shim size, with one "virtual button". The possibilities are infinite. I could write a book on how cool this app is. Perhaps I did.

Why not full screen? On my 7" Samsung tablet running 4.4, I'm getting a small image of the keyboard in the center of the screen with a large black border area all around. This app would be much easier to see and use if it was expanded to a full screen image.

I have put a link to the GitHub source repo in the store description, and it’s also in the about text in the app. There you will find tools for assembling programs from symbolic form and creating loadable program/library files. It's ok 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.

Lawrence D’Oliveiro March 28, 2014

Calculators in the 1970s didn’t have those functions. My Old Friend My TI58c got me through high school, trade school and college but it stopped working some years ago. I missed its simple but powerful programming and was pleasantly surprised to find this app. It's a really good recreation with modern conveniences. I use it every day. Good job and thank you!

Hmm 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.

Great also. 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.

reminds me of my first TI-30 back in about 1979 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.

Excellent!!! Includes all libraries and saving of programs. 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.

Wonderful Loving this latest update to an already awesome calc. Easier to hit/see the buttons now.

Not sure what you mean. Are the buttons unresponsive? Review deleted

# What's New

15611.5: increase size of tappable button area to see if that reduces complaints about unresponsive buttons; more consistent layout size on larger vs smaller screens; notification status now appears while program is running in background, not just when it stops; CE in error state now clears error state without clearing display.

15457.0: scale layout on phone-sized screens while centring on tablet-sized screens.

## Calcularis Scientific Calc

Calcularis: The only scientific calculator you will ever need.

A history feature will allow you to save as many equations as you need and allow you to retrieve them when needed or edit them. No need to press the = button because Calcularis is always calculating.

The full equation with multiple lines makes it easy to keep track of what your are calculating. All the standard scientific functions are on visible keys. There is a scientific and engineering notation mode as well.

Simply the the best free scientific calculator on the market.

The paid mode has the following additional features:

* applications such as Tip and split calculator, Loan calculator, math equations like quadratic equation.

* large set of constants

* unit conversions

* more functions accessed from the FN button

* more key layouts such as a 10 Key and Programmer/logical calculator accessed from the KEYS button

During the trial period (two weeks), you can use the features of the paid mode to try them out. After the trial period, the main features of the calculator will continue to work and will remain free.

Move over RealCalc, the new #1 Android scientific calculator has arrived. Some have asked the question whether you still need your TI, HP, Casio or Sharp calculators. The answer is yes. Phones are not usually allowed in the classroom or in testing centers. You will always need your old calculator for that. Plus calculators like TI-83, TI-84, TI-89 and TI-Nspire include graphing capability that is not currently supported.

Infinirule is a virtual slide rule application for Android. It transcends the limitations of real physical slide rules by allowing variable precision--just keep zooming in to get more--and automatically wrapping scales around--like a circular slide rule, but without the bulk. And though it only shows four scales at a time, you can select any combination of the available scale types.
