Fast, easy calculator for daily math, currency, percentages with after-call.

Editor, tools and utilities
Simple Calculator & Tools is a calculator for everyday sums. Its main jobs are arithmetic, percentages, and converting money from one currency to another, and the listing adds a set of number tools without naming them. The developer presents it as something you open and use straight away, without settings to configure.
It suits people who want to type a sum and read the answer, such as someone checking a bill, working out a discount in a shop, or comparing prices in two currencies.
The calculator handles addition, subtraction, multiplication and division. The listing points to percentage work for shopping, discounts and taxes, so you can find a reduced price or a tax amount without a separate tool.
Results are shown as numbers that the developer describes as clear and easy to read. The buttons are described as responsive, which is the developer's claim and not something this page has checked.
The app includes a currency converter that changes an amount from one currency into another. The converter is also one of the two tools that can be opened from the after-call screen, so a conversion can be done without leaving the phone call flow.
The listing does not describe where the conversion rates come from, so this page does not say how current they are.
After each phone call, the app can bring up the calculator and the currency converter directly. This is meant for quick sums or conversions that come up during or straight after a call, such as a price quoted over the phone.
The feature sits alongside the rest of the app rather than replacing it, so both tools can also be opened from the main app whenever they are needed.
The build we hold is Simple Calculator & Tools 28.0 (APKS split bundle) for Android 7.0 and up.
