Usually SilentNinja blocks unknown numbers.
It has an 'Intelligent mode', in which it only blocks unknown numbers that are not present in call logs (more details in settings).
In a meeting, SilentNinja can be configured to block all contacts too. Since your family numbers are usually present in call logs, they would not get blocked.
You can also blacklist numbers.
Any numbers SilentNinja blocks are visible in call logs. In short, SilentNinja keeps the user in control.
Use SilentNinja in a meeting or when watching a movie or whenever you need to filter calls. Keep SilentNinja in a quickly accessible location on your phone.
Note 1: SilentNinja does not create copies of your contacts, such as TrueCaller or other reverse lookup applications. You can install it safely on your business phones.
Note 2: We have an Ascending Ringer Volume feature. Disable this feature if you find the ringtone volume too low on permitted incoming calls. This warning is applicable only when the application in enabled.
