CoolApp is free to use and there are no ads, no affiliate marketers, and no tracking in CoolApp. As CoolApp is an independent nonprofit, development is supported by grants and donations from people like you. You are welcome to contribute or donate and we appreciate your support.

To get started with CoolApp, you will need to receive an SMS or call to register within CoolApp. CoolApp then uses either a mobile data or WiFi connection to function. While CoolApp does not charge for these, this may incur costs from your carrier or mobile provider.
