Iv tried most of the calculator apps available, this is easily one of the best out today, and has been for years now. The Pro version is 100% worth the $5 pricetag. If your work in any STEM field (as I do) this will quickly become your go to calculator.

Simply the best graphic calculator on the market. I was able to plot graphs immediately after installing. I can't say this for most of the other graphing calculators that I installed before to this one. It is very intuitive. For ease of use, It is well worth the $8.99 I paid for it.

This has all the functions needed to do 99% of math problems, great on phone or tablet. Please, please add the ability to turn the workspace backgrounds dark or light. *Edit: Thanks for adding dark backgrounds, the app works great. It's still the only calc app I use.

easily worth the money to upgrade to the pro version. this app has been a constant friend through years of high school math, all the way to my senior year at college, and will no doubt be there for many more years. best and easiest to use calculator on the app store

I'm an engineer and I love this calculator. It could use a button for POL/RECT next to the RAD/DEG button on the toolbar. EDIT: The only thing I don't like is the recent addition of the circular blue + button in the calculation/display view area (for adding a new entry), it obscures calculations and graphs in display area... is there a way to remove it or make it hideable?

I've been using this app for years and it is my go-to graphing calculator for all my work. It puts my old HP graphing calculator to shame. Edit: Original from 7/17/19, now 10/23/22 Still going strong, whereas my HP died years ago and I don't miss it. Note: I am sure my original purchase of this app was more than 10 years ago when I didn't post reviews, but this is too good to not post.

"I have the (paid) pro version. The app was working well, but quite all of a sudden in the graphing option email id is shown, which is dumb. Uninstalled and installed again, no use6. Wrote to the developers but they are keeping mum. Feel cheated." But sometime back I factory reset the phone. Now working well.

Best calculator and graphing app on the market. As an engineer, it's incredibly useful to have all this functionality in my pocket. It has quickly delivered real-time answers to questions in meetings without having to get out my laptop to use professional grade software applications.

Please add the ability to rearreange the placement of key "group". I am ambidextrous, and prefer that numeric keys are located on the left. Also, key looks cramp on a small screen, my finger is big. Might there be a way to improve? The help system would really shine if it is available offline.

Absolutely the perfect calculator to use when the free four - function calculators that came with your phone just won't cut it. Display transcendental functions, solve complex p5oblems in algebra geometry, calculu and more, and then display the results graphically. The interface is intuitive very well thought - out and simple t configured for scientists and simple to d by the way, I'm an actual person who've used this app for several years, and nobody paid me a penny to write this.

My favorite pocket calculator. The notepad like history it keeps is great for going back and checking my work, or changing variables later. It is great for easily setting up an equation with alphabetical variables, then assigning them numeric values that I am able to change on the fly; no need to rewrite the entire equation.

Can't recommend this app more, best calculator you can get for your phone. I just completed my degree in Aerospace Engineering and this calculator was my daily driver all through college. Used the free version for a while and the functionality isn't compromised. Then I upgraded to the premium version and it was well worth it. Again, I highly recommend this calculator over any other one you can find.

Highly Recommend. I've been using this calculator since high school, and it's helped BIG time. I've yet to find any other app that is as user-friendly and as well designed as this one. Even if you're not a "math guy," I recommend you have this calculator as to the default ones most phones come with. Because of this app, I didn't have to buy a ti-84 until my later years in college, and even then, I still used this app whenever possible. I highly recommend this app.

This app is just wonderful. It really shines on my tablet. It's easy to set up functions and then view them as graphs or tables. You can squeeze or stretch the graphs or tables to find areas of interest. Functions can be saved for later use. Really helpful if you want to explore math.

Best calculator app I have found. Lots of work space and calculations are accurate. You can hold multiple calculations at a time on a screen and move them whenever you want or delete whichever ones you want while keeping the others. I use it often whenever I need to save a calculation for later, such as my daily calorie intake.

Pro is missing a few important features. For instance one can't enter an equation and then switch to graph. Instead copy the equation, change to graph, paste. Why are the intercepts and the slope not calculated? An equation with two variables is resolved for one variable only, why? The app works, but to be useful it needs some additional features.

I am a retired engineer who tutors high school students in math. This graphing calculator is very powerful and is a pleasure to use -- especially compared to the antique TI-8x machines that are still in so many classrooms. My only complaint is that it isn't available for Chrome OS. The bigger screen would be wonderful, and Chromebooks are common in high schools.

I'm very much into calculators. This app was such a shock, to me, due to its powerful simplicity. For example, I just saw a poll on the news and it said, "there's a 59000 difference with 3% of the vote in" In this app I first typed 'x-y=59000' It beautifully entered that equation. Then, I clicked the "add equation button" The workspace is like paper. It simply adds a new area to make a new equation. Then I typed '.03(x+y)=59000' and it automatically uses the above to solve. I love it

Has been great for almost everything I have needed it for. Accurate and precise. Algebra has been a cinch with this. I hope that the designers continue to add more features such as unit conversion and maybe even possibly the ability to draw geometric shapes, assign values to their parts, and then use them for your math problems. Great overall.

Been using this calculator through many years & 3 different phones now. Easy to understand, intuitive to use and handles everything I throw at it. Starts up fast enough to be friction free for day-to-day use yet capable enough when actual calculations are needed (though my requirements are modest, mostly basic CAS stuff ). It's great to have a single app/interface for everything. EDIT: I recently had an app store related issue and needed customer support. Said support was quick and effective.
