Ratings and Reviews
great 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 :)
Advertisements are awful
This calculator would get a 5 star review from me if it didn’t have ads with sound that come up randomly. This makes this calculator useless if I am using it in a classroom, since I have no idea when these stupid and intrusive advertisements will interrupt my studying or the rest of the class. In fact, I was interrupted from my studies just now from an advertisement, and I decided enough is enough and wrote this review with the hope that the devs will remove the intrusive and interrupting advertisements. I’m fine with the banner ads, I understand they need to make money, but having these ads pop up in your face and making sounds interrupting classes or studying is just way out of line. If the devs remove the intrusive ads I will change this review and give 5 stars. Functionally, it works great, the display is awesome with a history of previous calculations to make multiple operations easy. It has all the functions of a scientific calculator that you would need. But
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.)
