1. 5/5Great calculator!

   I love this calculator! I’m a math teacher and have been using it for years. It looks and works just like the old TI-83 so there is no learning curve if you are used to the original. Because of the touch screen to make zooming and tracing easy the graphing is much better than the original and, obviously, much faster. The last update changed the display so that the lines of entries alternate colors, which I don’t happen to care for, but that is just a personal preference. The developer did (does) a fantastic job with this app. I don’t know how long ago I wrote the above paragraph, but it’s been several years at least. Since they asked, I’ll just say for the record that I’m still using it and I still think it is a great app. They asked again, and I will echo what I said previously. However many years later it is—and I’ve lost track—I’m still in love with this calculator. I use it almost daily, even though I’m no longer teaching. I still do some programming (project Euler mostly) and it’s hard to say how handy this calculator is.

2. 4/5Awesome++

   I have been looking for a truly powerful calculator for a long time. I've tried variations of the HP top of the line and several were very nice but as I said in one of the other reviews that calculator emulators are great for what they are but the idea is to serve your needs. If a calculator still retains all of the disadvantages of the original then it is not an advancement. This calculator not only provides all the capabilities of the HP that inspired it but also eliminates many of the physical calculator's cons. Ever had a calculator that did everything you needed and more but required a book and a lot of memory work to do any of the sophisticated things? This one does not have that drawback. There is context based help available at the touch of a button. Now you can actually use the full power of the calculator without it becoming a research project. To me, that essentially made the more advanced the calculator the less useful it became. Not so here. I applaud the developer. We don't need exact replicas of calculators, we need something to do a job with the least effort on our part. This is a giant step in that direction. On top of that, the developer continues to add additional enhancements without resorting to “forever pay”. This is truly a rare gem. Calculators are not sacred but my time is. Get this. You won't regret it. Now I can get on with my work!

3. 5/5It just keeps getting better AND .......Most likely It’s all you need and want😃

   I have said this before and I am saying it again be because this calculator just keeps getting better. Most likely it’s all you need! Ohh yess....did I mention the chemistry and Environmental engineering utility! From personal experience this is an ample scientific calculator that can get you through graphing, and bio-statistics,and physics. You will never misplace it, as it is on your tablet and smart phone in a pinch. The programmers care about your user experience, readily offering tips and promptly answering troubleshooting/ how to use the functions. The built help menus are unparalleled. This is one app I won’t be deleting to free up space! Also I think the user interface is extremely intuitive and rich with extras that you simply don’t get with all the handheld calculators that it replaces. Lastly it actually works natively smooth as if it belongs in iOS on your device screen.

4. 5/5Updated review

   I have a new device and an updated calculator. I left a review before but now want to update. I enjoy the developer took the time to fix all the bugs and improved the calculator. Math classes get more complicated and it is always great to know with the growing costs of books, school supplies, travel expenses and all things expensive, I am grateful to know there is an awesome developer that takes the time to improve this wonderful application and send all the loyal product users updates at no additional cost. Other developers and book writers would just add pages to a book, or improvements and label it new edition and charge for a new improvement…or more money for fixing the bugs. Thank you for being such an amazing and devoted developer. I will always look forward to purchasing new items in the future. It is also great to be able to review and refresh my math skills on the newly improved Graphing Calculator. Stay awesome!

5. 5/5Affordable for $truggling $tudents

   This is such a great app to use instead of a super expensive graphing calculator. I recommend it every year to my students. It’s fabulous for those on-the-spot study sessions at the coffee shop when you have forgotten your calculator. Many of my students have switched to it as their primary calculator. The functions are the same and the control over graph zooming is a simple pinch method. To identify mínima and máxima you just slide your finger over the graph until the color changes. no left and right bounding required. As an instructor, I use it with my iPad and OneNote during lecture. My lecture notes are projected to the overhead screen as I write them in OneNotes. When I need to demonstrate a concept on the calculator I slip it out by swiping left and a small version of the calculator is overlaid on my notes. When I am done, a swipe right allows me to return to only the notes screen. Students are able to watch my key strokes in real time.
