About Livecaller
What Is Livecaller
Livecaller tackles one of the oldest annoyances on a phone: an unknown number you have to gamble on. When a call comes in, it looks up the name behind the number and puts it on your screen before you pick up. Spam numbers get flagged at the same time, so a robocall never has to reach your ear.
The app is a lighter, single-purpose sibling of Sync.me, the broader caller ID and contacts tool from the same developer, Sync.ME LTD. Where Sync.me also syncs photos and social profiles into your address book, Livecaller keeps to two jobs. It identifies callers, and it warns you about spam.
The limits matter here. Livecaller is iPhone-only, and its number database is large but can't name every phone on the planet. Numbers outside its coverage simply show up as unknown, and the app leans on your carrier and iOS to deliver its lookup.
Getting Started
- Install Livecaller from the App Store and open it.
- Allow the permissions it asks for, including access to caller identification through iOS.
- Turn on the caller ID and spam blocking toggles in the app.
- Set it up once; it then runs in the background on every incoming call.
- Search any number inside the app when you want to check a missed call.

Key features
Real-Time Caller ID
The core feature shows a caller's name on screen as the phone rings, even when the number is not in your contacts. You see who is calling before you answer. It runs automatically on every incoming call once you switch it on, with no per-call effort from you.
Spam and Robocall Detection
Livecaller flags numbers reported as spam or associated with robocalls, so you get a heads-up before picking up. The warning appears on the call screen alongside the caller identification. For anyone hounded by telemarketers, this is the feature that saves the most time.
Number Search and Reverse Lookup
You can search any phone number inside the app to see what information is available and whether it has been reported as spam. It's handy when you miss a call and want to know who it was. The lookup covers both local and international numbers.
Global Number Database
According to the developer, Livecaller identifies over 4 billion phone numbers and known spammers worldwide. That scale is what makes caller ID useful for calls from outside your own country, where your address book offers nothing.
Lightweight, Set-Once Setup
Setup takes about 30 seconds. Turn on caller ID once and the app keeps working in the background with no ongoing management. That low-friction approach suits people who want protection without a new routine.
Privacy-First Design
The developer states that Livecaller never collects your personal information and keeps contact data on your device rather than uploading it. For a category that often raises privacy worries, that stance is a real selling point.
