How it works

It works without replacing your default call/SMS app.

For call: <br> It's the Caller ID app
For SMS: <br> It takes over the SMS notifications, it only filters the notifications, the spam messages will still be present in the SMS app.

💡 Please turn off the notification permission of the default SMS app in system settings, otherwise there will be double SMS notifications.

It's not necessary to leave this app running in the background, you can kill the process after it's configured, if it doesn't work, please refer to this.

Features:

Filter	It checks
Contacts	Whether from a contact
Contact Group	Whether it's a member of some contact group
STIR/SHAKEN	STIR/SHAKEN attestation
Repeated	Whether it's been calling repeatedly
Dialed	Whether you have dialed the number
Recent Apps	If some specific apps have been used recently, all calls are allowed.<br>Use case:<br> You ordered Pizza online and soon they call you to refund.
In Meeting	Decline calls during online video meetings
Off Time	A time period that always permits calls, usually no spams at night.
Spam Database	If it matches any spam number in the database. Any public downloadable spam databases can be integrated, such as the DNC.
Instant Query	Check the incoming number online in real time, querying multiple API endpoints simultaneously.
Report Spam	Automatically or manually report the number to multiple API endpoints to protect others and yourself.
Regex<br>(regular expression)	Check the Wiki for examples.<br><br>Some typical patterns:<br> - Any number: `.` (the regex `.` is equivalent to the wildcard `` in other apps) <br> - Exact number: `12345` <br> - Starts with 400: `400.` <br> - Ends with 123: `.123` <br> - Shorter than 5: `.{0,4}` <br> - Longer than 10: `.{11,}` <br> - Unknown number (it's empty string): `.{0}` or `^$`<br> - Contains "verification": `.verification.` <br> - Contains any of the words: `.(police\|hospital\|verification).` <br> - Starts with 400, with leading country code 11 or not: `(?:11)?400.` <br>- Extract verification code from SMS message: `code.*?(\d+)`
