Near perfect design with enough of the necessary functions (especially the fractions) to feel like my old Casio x10.

A Google User

Great app It's simple and it works just like it should be I lost my calculator I couldn't find it anywhere Had to do a math homework and your app just saved my ass

Rod Borst

I LIKE THIS CALCULATOR. IT OPENS FAST AND IS GREAT TO WORK WITH, WITH BIG KEYS TO WORK WITH. I HAVE TRIED OTHERS, BUT THIS IS THE BEST. GREAT FOR TRIG FUNCTIONS. OTHER CALCULATORS MAKE YOU HOLD DOWN THE THE CLEAR BUTTON, BUT THIS ONE CLEARS WITH ONE TOUCH. I LIKE THE CONVERT FEATURE. DID NOT EXPECT TO GET THAT TOO.

christopher skinner

Has a^b. And a√b. Good enough Replacing a graphing calculator which is more than I need. If u phone is big, keep both.

CalcTastic April 27, 2017

Thanks for the great review! Great application. Thanks to developer. All my phone/tablet have this app.

CalcTastic April 2, 2017

Thank you for the great review! I can't seem to do -log(). I just have to manually add them in the end.

CalcTastic May 27, 2017

Hey Ted, you can do this a few ways. -LOG(8) would be:
CLR, 8, LOG, -, =
CLR, LOG, 8, ), -, =
CLR, -1, ×, LOG, 8, =
-Sam Very good application as it allows you to establish a long and complex equation with easy featuring options

CalcTastic May 16, 2017

Thanks! This app is much and much better then others all type of functions is running I love this app ....

CalcTastic May 17, 2017

Thanks! 5 stars if the equation in history can be brought up and edited.

CalcTastic April 23, 2017

Thanks for the feedback. Unobtrusive, functional and very nice. Also the converter function is very handy.

Thanks! CalcTastic April 15, 2017

Thank you! Great calc. Love the theme support but I don't like not being able to customize the font: a dot-matrix and a 7-segment fonts should be included. And for the sake of realism, you should replace the hamburger menu icon with a fake brand logo and get rid of the upper bar buttons as these shortcuts are included on the keypad. All in all, it weirdly reminds me of RealCalc (the overall look -especially the Retro theme- and settings menu are almost twins). Maybe I'll eventually upgrade

CalcTastic March 6, 2017

Thanks for the feedback and review! Blows most other Calc apps out of the water. Greatest feature is being able to see full expression and then having it in recent history afterwards. Replaced my default app that swapped the 0 and .decimal point key (note 5), who does that??! Thank God for this app, took me a while to find the right one

CalcTastic March 5, 2017

Thanks for the great review!! 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 !

CalcTastic February 6, 2017

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 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

CalcTastic January 14, 2017

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

CalcTastic February 2, 2017

Thanks for the support! 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.

CalcTastic January 3, 2017

Thanks! 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.

CalcTastic February 14, 2017

Thanks for the review Mike! -Sam Tried a bunch, keeping this one I tried a bunch of scientific calculator apps and this is the one I'm keeping. I like the clean interface and the ability to use algebraic and RPN input (old HP-15C user)

CalcTastic January 17, 2017

Thanks for the review! 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! 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! Great calculator with RPN support. Being able to do statistics functions on the entire stack is nice, especially in conjunction with being able to look at the whole stack.

CalcTastic March 2, 2017

Thanks for the great review! 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. i cant do long equations!!! even i already get the answer part by part still a nooo

CalcTastic April 1, 2017

You should be able to do long equations no problem. Just remember to use parentheses. Probably worth more than five stars. An excellent application that does what it says. Simple to use and understand.

CalcTastic March 12, 2017

Thanks for the great 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! Very excellent scientfic calculator. Shows calculations and doesn't need permissions. Does radians and degrees. Five stars.

CalcTastic April 1, 2017

The HELP section has a pretty good explanation of angle-based calculations. Feel free to email me for more help.
