Protocol Deviation VS Allociao

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.

Questions & Answers

As answered by people managing Protocol Deviation and Allociao.

What makes your product unique?

Allociao's answer:

Allociao combines two data sources instead of relying on one: official phone numbering data published by telecom regulators (200+ countries) and real-time community reports. It also detects wangiri/satellite scam prefixes that most call blockers miss, includes an on-device SMS phishing detector (SMS Guard), and its premium tier extends protection to family members with AI-based cross-signal detection between calls and texts. The free tier requires no account and no ads.

Why should a person choose your product over its competitors?

Allociao's answer:

No account or sign-up required to use the free tier
Doesn't ask for invasive permissions or upload your contacts to a central server
Blocklist grounded in official regulator data, not just crowdsourced reports
Detects wangiri and satellite-prefix scams that many competitors ignore
Free core protection is genuinely usable, premium adds family protection and AI detection rather than paywalling the basics
