Voltage Divider is a free Android app developed by sunrasoft that supports two calculation modes. The first mode calculates the output voltage based on the specified values of the input voltage and resistance. The second mode calculates the resistance of the resistor based on the specified values of the input and output voltage.

The app is straightforward and easy to use, with a simple interface that allows users to input their values and get the calculated results immediately. It is a useful tool for anyone working with electrical circuits and needing to calculate voltage and resistance values.

Overall, Voltage Divider is a great app for anyone who needs to calculate voltage and resistance values quickly and easily. It is free and available for download on the Google Play Store.
