Allociao
Free Android app that automatically blocks telemarketing and scam calls, using official regulator data and community reports.
Allociao is a free Android app that automatically blocks telemarketing calls, robocalls, and phone scams, with no subscription or ads required for the core protection.
Instead of relying on a single crowdsourced blocklist, Allociao combines two data sources: official phone numbering data published by telecom regulators (covering 200+ countries, including satellite and premium-rate prefixes commonly used in wangiri scams) and real-time reports from the Allociao community. Calls from known contacts always ring through, the app never screens people already in your address book.
Beyond call blocking, Allociao includes SMS Guard, an on-device smishing detector that flags suspicious text messages, such as fake delivery notices, fake tax refunds, or bank phishing, using multilingual keyword and pattern analysis, without sending your messages to any server.
For families, Allociao+ (an optional premium tier) extends protection to relatives: a shared blocklist, a family dashboard showing which calls and texts were blocked for each member, and an AI-enhanced detection layer (on-device models) for both calls and SMS that catches more subtle scam patterns, including social-engineering messages with no link, like a stranger pretending to be family with "I changed my number."
Allociao asks for the minimum permissions necessary, avoids restricted Android permissions where possible, and does not require an account to use the free tier. The app is available in 72 languages and covers phone numbering data for 200+ countries.
A startup from France.
