July 08, 2025
Well, that day has come, and it’s likely that you’ve forgotten the formula. Fortunately for you,All-In-One Calculatorfrom MINDBOX has your back, packing in pretty much every conversion tool you might need and more.
All-In-One Calculator is much more than what meets the eye. While most standard calculator apps found installed on Android phones by default allow you to add, subtract, multiply, and divide, All-In-One Calculator provides tools for algebra, geometry, unit conversions, finance, health, and more.
One of the more handy calculators is the built-in currency converter. By default, the app shows you the conversion for U.S. dollars to euros, but you can easily add almost any currency to the tool. Plus, MINDBOX even includes a timestamp that shows the last time the converter was updated that way you know that the All-In-One Calculator is using the most up-to-date exchange rates.
If all of the various calculators are a secondary use for you when opening up the app, there is a Calculator mode that can be enabled in the settings menu. With it turned on, the standard calculator will be the first thing to pop up whenever the app is opened.
One standout feature of All-In-One Calculator is the ability to place shortcuts to any of the built-in tools onto your phone’s homescreens. This option can be convenient if you’re repeatedly doing the same calculation. Plus, in a sense, this feature can turn each conversion tool into a standalone app.
If theming is essential for you, this app’s developer has you covered. While other apps might offer you the choice between a dark and light theme, All-In-One Calculator provides over 40 vibrant dark and light designs to choose from.
But what’s really impressive is that All-In-One Calculator was built by and is maintained by a single developer. So the fact that they were able to pack all of these tools into a beautifully-designed app that only takes up 22MB of space is fantastic.
And we aren’t the only ones who have been taken by this app. Looking at the Play Store listing for All-In-One Calculator, the app currently has a 4.7-star rating with over 31 thousand positive reviews. This overwhelming support from the community isn’t at all surprising as the app is extremely stable and provides fast and accurate conversions.
