Only those in your contact list can call.
Call Blocker rejects, before ringing, all calls from numbers not in your contacts. Telemarketing, debt collection, surveys, and phone scams stop interrupting your day. Those in your contact list continue to call normally.
How it works
• You select the app as "caller ID and spam" on Android with one tap.
• For each call, the app compares the number with your contact list on your device.
• Numbers not in your contact list are rejected without ringing or notification. Numbers in your contact list ring as usual.
What you control
• Block all unknown numbers or only those from certain area codes. Select all and deselect those that should ring.
• Dual SIM: choose which SIM card to block, with the nickname of each SIM card.
• Pause for 1, 4, or 24 hours when waiting for a delivery, a doctor's appointment, or a service.
• Always allowed numbers: exceptions for clinics, schools, or delivery people not in your contact list. • Call history with the reason for each decision, the caller's SIM card, and the contact's name. Tap to call back or to allow the number.
• Daily summary, silent, with how many calls were blocked.
• Light, dark, or system theme.
Privacy
• Everything happens on the device. Your contacts and call history never leave it.
• No registration, no ads, no server, and no internet required to function.
• Permissions: contacts (to compare the number) and, optionally, phone status (to identify the SIM card) and notifications (for the daily summary).
In-app tips
Registration with Anatel's "Do Not Disturb" service, blocking unknown numbers on WhatsApp, protection against SMS spam, and habits that avoid phone scams.
Requirements and limits
• Android 10 or later.
• Only one app at a time can be the Android caller ID. While this app is acting as such, spam identification from Google Phone or Samsung is disabled. You can switch back at any time.
• Calls via WhatsApp and other messaging apps don't go through the carrier; the app shows how to silence them in the tips.
• On some devices (Samsung, Xiaomi, Motorola) you need to enable the battery optimization app. The app guides you through the process.
