Android call screening

Scam calls from abroad never ring.

Intl Call Blocker uses Android's built-in call screening to drop overseas robocalls and one-ring Wangiri scams before your phone buzzes. Core blocking runs entirely on your device.

How it works

Decided before the first ring.

Android hands every incoming call to the screening service. We check it against your rules and answer in milliseconds.

Check the number

Country code is compared with your SIM's home country, your allowed list and your custom prefix rules.

Block or allow

International and hidden callers are rejected at the OS layer. Contacts and allowed countries ring through.

AI second opinion

Premium sends unknown numbers for a 0–100 scam risk score from Gemini in asia-south1.

Features

Quiet by default. Flexible when you need it.

Smart SIM detection

Finds your home country from the SIM or carrier network automatically.

Allowed countries

Pick the foreign countries where family and friends live so their calls ring normally.

Contact safe-pass

Anyone in your contacts is never blocked. The lookup happens on-device and nothing is uploaded.

Wildcard rules

Block exact numbers or prefixes such as +1202* or +44*.

Scheduled hours

Only block overnight or on weekends, whichever suits your day.

Cloud sync

Settings sync across your devices through Firestore in asia-south1.

Pricing

Start free. Upgrade when you need more.

Subscriptions are billed through Google Play and can be cancelled any time.
