About this app

Tired of your phone ringing for calls you never asked for?

Allociao screens out telemarketing, robocalls and unwanted callers before the first ring ever reaches you. The result: quieter days, and real peace of mind about the scams that can cost you money.

How it works
Install the app, set it as your call screening service, and you're done — it runs quietly in the background. A known spam number gets hung up on without ever bothering you. A questionable number puts an alert on your screen, so you can pick up with your guard up. Your family, friends and trusted numbers always get through, no obstacles. And you stay in charge: you can allow or block any number at any time.

Not sure about a message? Check it before it gets you
Most scams show up as messages: a fake delivery notice, a fake bank fraud department, a booby-trapped link, a sketchy QR code. Allociao gives you eight ways to check, all on your phone:

• A text message — paste it in, or share it straight from any app
• A screenshot — the text is read right out of the image
• A PDF
• An email, or just the sender's address when it smells like spoofing
• A link — and if it's shortened, you can see where it really goes before you open it
• A QR code — scan it to see its destination before it loads
• An attachment — Allociao reads the file's real type, even when it's disguised as a PDF

And you find out why
No black-box verdict. Every red flag is explained in plain English: why that address is imitating a site you know, why the message is pressuring you, why a real company never asks for your login by text. You learn to spot them yourself.

What changes for you
No more being interrupted mid-afternoon by sales pitches. More importantly, you avoid the traps that empty a bank account: you stop calling back a premium-rate number after a suspicious missed call, and you recognize a con artist before you hand anything over.

Who it's for
Anyone who's had enough of the interruptions: a parent or grandparent that scammers keep targeting, a freelancer buried under sales calls, or simply someone who wants a phone that stays quiet.

Community strength
Anyone can report a bad number anonymously, or confirm that a number is legitimate. Together, those reports catch new fraudulent numbers sooner. A clear history shows you at any time what was screened out, and why.

Free, and respectful of your privacy
Allociao is completely free and ad-free. Call screening and message analysis run locally on your device — the content of your messages never leaves it. Your reports stay anonymous.

In detail, Allociao gives you:
• Automatic blocking of known telemarketing numbers, from official number ranges built into the app (over 12 million entries)
• Filtering of withheld, private and hidden numbers
• Eight checking tools: text, image, PDF, email, email address, link, QR code, attachment — 100% on-device analysis
• Detection of internet numbers frequently repurposed for spam and fraud
• International coverage: number recognition for many countries, plus rules tuned for calls from abroad
• Personal lists: your blocklist and your allowlist, sorted by category and filterable
• A visual warning on the call screen for risky callers
• Fully adjustable notifications for screened calls
• Caller identification and a detailed history of every call handled

Take back control of your phone. Install Allociao and enjoy the quiet.

What’s new

This version is far better at spotting scam messages.

It catches the “Hi Mom, I have a new number”, fake delivery notices, fake unpaid-toll notices and fake bank staff. And above all it tells you why: every signal is named and explained, so you can spot the next one yourself.

New: if you want to, you can share the messages you have analyzed to help protect everyone better. It's your choice, and you can turn it off at any time.
