Identify calls and get alerts for unwanted calls
- The app automatically shows you who's calling before answering and alerts you to calls you may not want to answer.
- To identify calls, some phones (such as Huawei and Xiaomi) need to access the Battery Manager app and make sure our app is on the list of protected apps so that it can work in the background and wait for call.

Report unwanted calls
- After a call, you can report the number so that other users do not have to answer the same call.

Block calls
- Block any numbers you want to avoid calls from.
