1. 1/5Ads out of control

   I’ll start off by saying I have loved this calculator for over a decade. I first downloaded this calculator 29Dec2012 and have used it regularly. One might ask why would I give a one star review to something I’ve used for so long for free? The first 6 or 8 years or so there were absolutely no pop up ads. I think there may have been an ad banner at the bottom for a while but nothing crazy. It’s been a few years now that the ads have started increasing. I haven’t had a problem with that because they weren’t too bad. It started out with an ad that would pop up once every few times using it and would allow me to close it out pretty quick. It’s been getting more frequent and longer lasting ads. It’s now that every single time I go in to use it, one pops up and makes me watch a 15-30 second ad every single time. There are way too many options out there that it’s about time for me to delete this one and find a new one. Guaranteed I can find one that doesn’t have ads. Maybe I just go back to the one Apple provides. Been a good run for the past 12 years but I guess all good things do come to an end

2. 5/5It’s awesome.

   I never leave reviews, but this app is so worth it. It’s so easy to plug in the numbers exactly how I want them. Who cares if there are ads? The 15-30 second video just plays at the beginning. It’s not that big of a deal. There are so many things that you can do on the calculator that are free. If you’re in high school, you’ll be fine. Usually apps give you very limited options before you have to pay; this app is not like that, which I really appreciate. Whoever made this app, thank you so much for making a scientific calculator app that’s really convenient.

3. 5/5Absolutely Excellent

   Before retiring I was An intercontinental ballistic missile designer. Mathematical calculations were my daily bread and butter. This calculator can do, for free!, what our most expensive calculators could do. I am amazed that such a powerful calculator is now being offered at no cost to anyone who needs a small hand-held calculator. Thank you so much for making this calculator available. I highly recommend this calculator. (The only down-side to this calculator is that it does not use reverse-Polish notation which requires fewer key strokes. But no one uses reverse-Polish nowadays anyway, much less knows what it is.)

4. 5/5Brilliant app, thanks for holding off on the ads until I got use from it

   Just wanted to say thanks for holding off the ads until I had used this app for a week or two. Great little piece of technology. Bought the infinity calculator earlier today ... Looking forward to it being worth the purchase. Gotta say, those full page ads were super annoying, but I get it. You made this thing a demo for the infinity, which is still CHEAP. Thanks, developers. I hope you carry on well.

5. 5/5great for homework/online students

   Because of schools closing due to COVID-19 it’s been hard to adjust to online learning especially because i don’t have all of the resources and supplies that i would have at school regularly. Especially in math because i don’t have the money to buy a nice calculator and the school doesn’t provide any. This really saved me because it had all of the tools needed to help solve and understand the stuff that we’re working on and learning at this time. I could just use a website on my computer buts it’s way easier and more convenient to have it on my phone rather than switching the tabs back and forth :)
