  • A spam indicator
  • Number of spam reports
  • A label: likely business
  • AI Data

No confusion. No guessing. Just clarity.

On iPhone, recognition should feel instant. Sync.me uses simple, intuitive indicators directly on your incoming call screen:

    the caller has been identified. You'll see their name clearly, so you can answer with confidence.
  • 🚫 Spam or Fraud
    if a number has been reported as spam or suspected fraud, you'll see a strong warning before you pick up.
  • ✨ AI Insights
    when available, enhanced AI data adds deeper context to the caller, helping you better understand who is reaching you.

AI Tags. More Than Just a Name.

AI Tags. More Than Just a Name.

A name tells you who. AI tags tell you more. Sync.me adds intelligent context to recognized callers, such as:

  • Job title
  • Place of work
  • Business industry
  • Professional category

So you don't just see a number. You understand who's reaching out. Smarter context. Faster decisions.

A Caller ID Built on Real Data

Sync.me has been identifying unknown callers since 2011. The app's accuracy comes from two sources working together: a global database of over 5 billion phone numbers and an active community of over 20 million users submitting spam reports in real time. That combination – scale plus continuously refreshed data – is what makes every caller ID check reliable rather than just fast. A number reported as spam in one country gets flagged for users everywhere, often within hours.
