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 Rainlendar 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

How would you describe the primary audience of your product?

Allociao's answer:

Everyday smartphone users tired of telemarketing and scam calls, and families who want to protect relatives (especially older parents) who are common targets of phone scams. The app started in France and is expanding internationally, with phone numbering data covering 200+ countries and a UI in 72 languages.

What's the story behind your product?

Allociao's answer:

Allociao was built by a solo developer frustrated with spam calls and unsatisfied with existing call-blocker apps that ask for heavy permissions or upload your address book. The goal was a privacy-respecting alternative that still works well, using public regulator data and community reports instead of harvesting user contacts.

Which are the primary technologies used for building your product?

Allociao's answer:

  • Native Android app in Kotlin with Jetpack Compose (Material 3)
  • On-device machine learning for spam scoring, no call or message content sent to a server
  • Nuxt 4 website
  • Serverless Postgres for the backend

Who are some of the biggest customers of your product?

Allociao's answer:

  • People fed up with daily telemarketing and robocalls, looking for a blocker that actually works
  • Scam and fraud call victims (or near-victims) wanting proactive protection
  • Adult children setting up protection for elderly parents who are frequent scam targets
  • Privacy-conscious users who refuse apps that upload their contacts or call log to a server
