Tejas Naik

It's interface is very intuitive. Although it could use some tinkering regarding its typing predictions. It incorrectly corrects our entry sometimes. Other then that thumbs up !

Ilham Akbar

Need help I'm not a student of any natural science class, but my friend is. I recommend her to use this app cuz I see it has good review and rating. Can you guys tell me how to use regression feature? TIA

Arlen Ferguson

I rarely give 5 stars but I almost did for this app. There are no adds and advanced functionality. This is now one of my favorite apps.

Steven Marzuola

Great! Needed a quick calculation And the built-in calculator on my tablet couldn't handle it. Couldn't use trig functions on numbers in the display and no memory. This one fit the bill.

Mike H

I pretty much never review apps. This one is fantastic! The interface is very close in design to my older Ti-30X, which is generations of designs in the past. Intuitive, clean, and well done.

Tejas, thanks for the review and feedback! It should only reduce fractions and things of that nature. Let me know if you see something else. -Sam CalcTastic January 14, 2017

Thanks for the review! There's a section for the statistics here: http://calctastic.com/help/scientific-mode/#statistics CalcTastic February 2, 2017

Thanks for the support! CalcTastic January 3, 2017

Thanks! CalcTastic January 17, 2017

Thanks for the review! CalcTastic February 14, 2017

Thanks for the review Mike! -Sam i reckon this here is the best calculator app i have found --- its a bunch better than the stock calculator on my nexus 6. thanks y'all!

CalcTastic January 31, 2017

Thanks for the review Brad! No ads and works as advertised. Also, it installed to my external memory memory card so that it does not use up my main memory.

CalcTastic February 6, 2017

Thanks for the review and support! So far so good Good intuitive calculator so far with plenty of functions. Worth while up grade from stock Droid Turbo calculator.

CalcTastic January 13, 2017

Thanks for the review. Awesome Finally found a calculator that works like a real calculator. Plus it has a tons of extras. Happy to support the dev.

CalcTastic January 6, 2017

Thanks for the review and support! The best scientific calculator ever used in my phone......Has all of what u can think...

CalcTastic February 18, 2017

Thanks for the review! CalcTastic December 28, 2016

Thanks! CalcTastic February 10, 2017

Thanks! CalcTastic February 16, 2017

Thanks for the review, tell me what I can improve upon. CalcTastic February 6, 2017

Thanks! Good stuff! But with a few improvements: The app icon sucks. When I need calculator, I ended up tapping any app around it, except CalcTastic; And why there is no ANS button for a scientific calculator? Or it is hidden with different name?

CalcTastic December 8, 2016

Thanks for the feedback and review. You can tap any of the history items to use them again in a new calculation. Works I've recently went back to school and on a tight budget my calculator is still lost in one of many boxes since we just moved and can't just go out and buy one this one works great for what I am doing in school right now awesome app

CalcTastic December 14, 2016

Thanks Kimberly! Need something You could not edit calculations that have been calculated.

CalcTastic November 24, 2016

Thanks for the review and feedback. There is a plus/minus for negatives. Amazing app, deserves 5 stars with no queries asked . Thank you developers 😃

CalcTastic February 20, 2017

Thanks for the great review! CalcTastic December 1, 2016

Thanks! CalcTastic November 25, 2016

Thanks! CalcTastic December 23, 2016

Thanks! CalcTastic December 26, 2016

Thanks! Superb If matrix operations are added , it would be sooper cool (like liquid nitrogen)

CalcTastic October 5, 2016

Thanks Aandrew! Good but with annoyances Very good but the annoying trailing decimal point is... well, very annoying. For example, "21 / 3 = 7", not "7."! It's also potentially confusing hinting at something missing. Weird.

CalcTastic October 24, 2016

Thank you for the feedback and review. CalcTastic November 1, 2016

Thanks Jose! Very Nice But I found an even nicer one (for $3.49). Pros:. no ads; RPN notation; premium/paid upgrade for just $0.99. Cons:. fonts aren't as large/readable as they could be.

CalcTastic June 5, 2016

Thanks for the review and feedback. What else did you get? Great calculator Simple to use, everything you need is there. Just one thing: the CLS button is too easy to access and I've cleared the stack (in RPN) by accident!

CalcTastic May 26, 2016

Louis, thanks for the feedback. Super. I have tried a number of scientific calculators and can confidently say that this calculator is the best by far. It is very easy to use, performs statistical calculations, has nice big easy-to-read fonts etc. I particularly like the "Stack " concept where it stacks up the last 20 (expandable up to 50) operations for easy recall and further processing. Handles RPN logic for those who like to work this way. Algebraic entry displays expressions as you would see them in books. A masterpiece, I might add.

CalcTastic August 27, 2016

Thanks again Vs Lingam! Good But I noticed one thing, you cannot raise anything to a negative power. For example 6^(-6) or 3 * 10^(-2.5) etc are not possible to calculate. Please add this functionality. This is by far the best scientific calculator I have used.

CalcTastic September 27, 2016

Thanks for the review! You should be able to enter negative powers just as you described though. Try: 6 ^ ± 6 = This calculator is made to be the best Even free version is utterly featureful, good looking and comfortable. Plus has a lowest price you can express a respect to the authors with.

CalcTastic August 2, 2016

Thanks for the review and feedback! Best scientific calculator I've tested many and this is the best one! Not only full of functions but also most importantly user friendly! Just use the 'root' function and compare it with others you will see!

CalcTastic October 24, 2016

Thanks again! Scientific notation If it had an ability to help with scientific notation then I would have been content with the app

CalcTastic October 6, 2016

Kitty, there's a guide in the HELP section, but feel free to send me an email with any questions.

Thanks Alan. CalcTastic October 24, 2016

Thanks Chris! CalcTastic September 19, 2016

Thanks Ron. Very nice Great skins. Would like to be able to hide the top bar and also reduce the display to one expression/answer.

Thanks for the review and feedback! CalcTastic March 13, 2016

Thanks for the great review! Simple and very comprehensive. Will never need another scientific calc.
