★★★★☆Melaram Banjare· Feb 5, 2026
Loan amount ka chart, details me Mikhail dene chahiye. Aur apps hide karne ka bhi option hona chahiye.
★★★★★Krupal S Gowda· Aug 30, 2024
Absolutely awesome calculator app, very polished and feature rich app. Would love it if you add the Indian numeral system.
★☆☆☆☆C Aurelia Andromeda· Mar 7, 2026
Constant data breaches with constant ads' vender consent re-requests. DO NOT USE.
★★☆☆☆iyad· May 13, 2023
Would've been a 5*. The app is full of functionality and I love it, but the new redesign sucked all the personality out of it, it now just looks like the blandest generic calculator you can find.
★☆☆☆☆Afzal Inamdar· Dec 27, 2024
🇮🇳 Make Numbers alignment according to Indian Currency in the Calculator Example, 1,000 10,000 1,00,000 10,00,000 1,00,00,000
★☆☆☆☆Stephane Rocher· Jan 23, 2024
To give or not to give - that's the problem! I used to enjoy using the calculator, but now it won't let me use it anymore. Every time you start the app it asks for your consent to let hundreds of companies use your personal data. I do not consent! However, next time it pops up again. So in order to use the app you have to consent. Shame I can't use the app anymore.

Where are the tiny units like Micrograms
