5 stars: For scientific calculator in aadvanced mode, this is the best of the best. Contains from elementary calculation button to advanced topic computation, plotting to 3d, vector to differential calculus and then integral calculus what else not! Superb design and theme are extra gain. Many many thanks to the developer to make this app. It completely substitute the need of computer oriented heavy software. Thank you once again!
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: 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: Class. The way it shows the results and in the variety in which it shows it...
