5 stars: Great scientific calculator. It has an awesome chemistry calculation too and maths formula. It's a multi-functional calculator. And bug free. The only down is it can't do integration and differentiation Engineering high grade calculation but it pretty does a programmer calculations (pro version though). But clearly it's all good awesome app. Jah bless it's makers.
5 stars: This App is so awesome! It provides you with almost all mathematical features you need in Engineering, Accounting, Economics etc. Also very easy and convenient to use. In fact, I don't think nothing is lacking in this App. Everything you could thought of has been covered up here.
5 stars: Very good design definitely handy if you forgot your calculator in class. What I would love to see would be some more arrow keys to go left and right since it's a little hard with my finger to tab on the exact spot if I miss typed something but other than that it's really good to work with that app.
5 stars: I love this author's work but they seem to keep making new similar apps rather than updating old ones. I paid for pro on a previous one;one new app came out that let me go Pro without paying as a result of the previous payment but this one doesn't. I don't want to pay for pro every update.
5 stars: I must say the developer is doing a great job. This app is a real Scientific Calculator and an advanced one. I complained about my purchase and the developer responded accordingly and my problem is 1...
