Sunrise Sunset Calculator Free is an Android app developed by SoloCrowd that provides you with the sunrise and sunset times for your current location or any other location of your choice. This small and fast app is perfect for outdoor enthusiasts who want to plan their activities based on the time of day. It is a free app, but you can upgrade to the full version for widgets and an ad-free experience.

One of the best features of this app is that it offers three methods for finding location and timezone. You can use your device's GPS to determine your current location and timezone, pick a city from a provided list, or use a Google Map to specify a manual location. You can also create a customized list of your favorite locations and manually adjust the latitude, longitude, and time zone for each. The app works without an internet connection, except for the Google Map feature.

The app is designed to save your battery life and put the control of the GPS in your hands. It barely uses the GPS and turns it off right after a location is found, unless you request an updated one. You can also customize the display to see more or less details, show or hide seconds, AM/PM, and if the US or EU daylight savings time is used.
