Very configurable and permissionless. Paid version is costly. Per theme purchase should be allowed. Material theme should have a darker colored display area instead of current white.

This is the best calculator I ever had in my phone, and I've tried a few! I don't even want to hear about the others. Very customizeable (buttons, number format, precedence of operation, rounding rules, and even more exotic things), useful memory and calculation history functions, easy to use and at the same time, packed with advanced features! This app does an outstanding job of providing a calculator that is good for basic things, but that allows you to tinker with the fine details, if you would like to. And on top of that, it's free! Is it OK for me to be this excited about a calculator?

Works well and no adverts. It does lag when you have Android magnification switched on

Excellent, multipurpose. I find the history function very useful for comparing account figures over time

I'm older & like my calculators with lots of functions and few areas with which to waste time. This one fits the full-function, no frills definition perfectly! I've been using this calculator since 2017 and haven't ever felt the need to look for something else. They are announcing a new version in the fall or winter of 2025 which I am also looking forward to - There is not much room for improvement so it will be interesting how they bring this app to another level!

Application does not store memory functions in history, for example if I do calculation (500 * 5 + m + and 200 * 3 M+ ) And see the result as MR which is 2100.00 But this calculation does not reflect in history. It would be great if this calculation is also included in history so that we can recall the same. In addition to above please see if we can add Tax+ and Tax- buttons for GST calculation.

I’ve used Mobi Calculator for many years, and it’s still my go-to app. The history, memory, and more digit options are very handy, and it runs smoothly without ads or bugs. A perfect example of a well-made, efficient utility app. Kudos to the developers!

In 2014 I wrote: "It's a super little tool, and its most appealing feature is that it remains simple despite its knowledge and flexibility. I'm usually stingy with praise, but it's really earned it here. My respect to the developers—they did a great job!" Now, after 11 years of usage​ I still think: this is the best calc app you can get! Thx for the great job! 🤗

Still the best calculator app. I have multiple calculations in the app, which I use to track my spending. A minor issue in the latest update still needs fixing. One can't see the result of the bottom calculation on both History and Fixed screens.

Using it from a very long time fully satisfied all functions makes work easy quick and accurate. one of the best calculators I have used. I want to know if you can make something the same or similar for iPhone platform because I can't find anything on the iPhone like your mobi calc.

I've literally downloaded dozens of calculators trying to find the best one. I feel this is it! No ads, customizable calculations, simplistic look. The only improvement would be to add a feature where the calculation will continue every time the = is pressed (2x2=4=8=16=32...) still 5 stars and the best calculator app out there.

I've been using the Mobi Calculator (Google Play Store) for a year. During that time, there have been two, [2, with one today], upgrade to PRO Version solicitations. I am not a "math" guy. The current free version does everything I need it to, including maintaining my calculations history. If all you need to use it for is paying bills, then this is the calculator to own. What's really cool is that one is not held "hostage" when saying "no" to the upgrade. The Mobi Calculator - Awesome!

This is an excellent easy to use calculator application. The keyboard can be expanded to do a great deal more complicated calculations than most people can do. The history option is a nice feature which is very useful, helpful and allows you to go back to review the input you entered and/or correct any mistakes/errors you may have made.

There aren't too many things left that are truly free of any monetary cost. And, other than the NBC Sports Predictor app, this Mobi Calculator app is the only other one I can think of that is 'truly free.' It is able to perform more operations than I will ever use. And, it's History saving capability is really very cool. So, if one needs it to perform advanced Calculus or just the most basic add/subtract ops, I recommend the Mobi Calculator without hesitation!

This is simply THE BEST calculator I've ever used. It's pretty, simple and contains a lot of functions. And you have opportunity to change some of the buttons, which I find really great. Interface is very friendly and you get used to it really quickly. I'm a physics student who needs to use calculator quite often. Recommend it to everyone!

I've been looking for a nice, simple calculator app to replace the one that came pre-installed on my phone. Each calculator I downloaded was either inundated with ads, or were just trying to do too much and trying hard to make you pay a subscription. I dont want to buy a subscription for a calculator. This app here is just a nice, simple calculator, which is exactly what I wanted.

Finally! Simple, advanced, and no ads or strange permission access for a calculator app! I just needed something to use for a time calculator and this works. Only used it for a few seconds so far (no pun intended...), but I'm now curious what else I can use it for in the future. Thank you for sharing a great ad-free and efficient app! I'll be checking out what other apps you have available as well.
