  1. Anjan Debnath-avatar

    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!

  2. Michael Agbana-avatar

    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.

    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.

  4. lukas fuessel-avatar

    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.

    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 100% resolved. I recommend you buy the premium version to earn all the features of the calculator. GREAT APP!!!

    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.

  7. kobby bartons-avatar

    I've even started using but I really must say I'm impressed by the interface. Also, the "mode" function comprises of all the "mathematics aspects" mainly matrixes, equations , Statistics, inequalities up to even degree 4!!!! Absolutely unbelievable!!! You guys have made an absolutely outstanding app. Looking forward to making my first purchase of the pro version 😍😍 I ⭐⭐⭐⭐⭐[ five star straight up]

  8. Hamza Sajid-avatar

    The calculator looks and feel awesome except the directional buttons. I'm so used to casio d-pad that it is really uncomfortable for me to use that. Can you please change the layout of directional buttons to something like D-pad? I'm sure other people must have also felt the same thing.

  9. Reuben Dale-avatar

    It does everything you want a calculator to do and it does it well with no ads, slowness or anything that isn't useful to the user, 10/10, would recommend to anyone that needs a more advanced calculator that the inbuilt one in your phone

  10. Godwin Sunday-avatar

    Easy and fast Fractional expressions. Mathematical formulas available. BODMAS obeyed (meaning, you can type things of +, -, * and / at same time). Results can be recalled. I love it more than others cuz it contains (more than) all I NEED

  11. Nate Evans-avatar

    Best free scientific calculator I have used to-date. The development team has done an excellent job on the layout, functionality, and scope of possible mathematical operations.

  12. Dar Javaid-avatar

    Very nice app.Feels so comfortable to use it. Was having some problem in getting premium version after paying, however admin helped quickly. Need some more development like every calculation to add in history without pressing answer

  13. Srijan Sarkar-avatar

    This is so much good. It is more better than my thoughts. 😊😊😊but here more infinity series must be include like Ramanujan series, etc... But inspite of this, it is one of the best app of all time.

  14. Adiba Khatoon-avatar

    It's a very helpfull app.... I love it...the design of the display is quite good...and I think it contains alot of function about which I've no idea.... In a nutshell...its a very good app.

    Absolutely beautiful and user friendly, but it fails to do something more complicated like this: ((1-sqrt{33})/4)^(1/5) The results shows 0.83711.. But the answer is -1.03473..

  27. Vaibhav Gupta-avatar

    Does exactly what you want! I am giving 4* bcoz, although, mind you, the app is perfect! BUT I don't know why do they keep releasing a new app and ask us to replace the previous one with the new one! They can just update the app or leave it be. I implore the devs to pls seriously consider this advice of mine. Thank you.

    I use very few of the features that this app provides, my main tool is Excel. However, I love that I can see the whole formula I type (like a real calculator). The typing speed is also higher than the previous app I was using which makes it much more comfortable to use. The default 'skin' is great! Thanks!
