Very good App. One suggestion, while doing \"Back\" button on mobile the application should go to it\'s main screen (calculator screen) and after second time pressing the Back button the application should be exit, which is not happening. Please incorporate that function. Thank you.

For the Paid version. Worth every penny.
Mohit Kanva 2020-10-16

App is superb with all the essential features. It is easy to use. Note:- One thing which I do not like in this App is- When you do long calculations or use GST calculator, the right most fonts along the right edge of my mobile phone get hidden partially. I am using the App on One Plus 7 handset. Please work on this issue at the earliest. Regards

I really appreciate your efforts to keep it \'Totally Ad-free\'. It is very useful app and easy to use with decent interface. During your next update, is it possible to add \'Birthdate Reminder\' feature in Date Calculator. So that without opening of app one should be reminded about Birthdate occurence.

A very nice application. It can be used for every single calculations. Great efforts in making this application. It\'s easy to use and convenient. It can help you in health also. It calculates according to your weight, height and age that how much calories you have to burn and how much water intake should be there. A very nice application for everyone 👌😊

UPDATE: still a great app! Does all kinds of useful calculations and conversions including loan calculations, tips, BMI (body mass index), currency conversion, date calculations, interest calculations, discount calculations, and solving simple equations. The developer just keeps making it better. I recommend it to everyone.

Very decent and helpful calculator. Wondering if there\'s a way of getting rid of the ads, purchasing a licence perhaps?
Biju Mathew Ozhakkal 2020-11-22

Systematically designed layout, logically thought out and derived from a functionality perspective. One of the best I have seen. It covers all our needs for instance loan calculator and amortization chart is also available.
Denis 2020-08-18

Wow, It is fully packed calculator with all the necessary tools such as converters, interest, unit and ..etc. It occupies only 5MB in your internal storage which you can\'t get in any calculator app out there with these functions. NO ADS ! and different themes

I have purchased but still its showing try to purchase again...Rs 150 also deducted from my account. Deepak ji you have to do something in this matter.. I have rated 5 star because I like your Calculator so much. if you want i can share transaction details with you. in transaction details clearly mentioned your name that is \' Sold by Deepak\'.
