Best forkeeping an address book organized and backed up
Contacts is the clearest choice for managing an address book rather than screening calls. Its groups, search, email-account integration, and contact backup make it more focused on keeping names and details organized than Truecaller or CallApp.
It is free, has no ads or in-app purchases, and has the largest install count of the three at 5,000,000,000+. The trade-off is that it does not offer the caller ID and spam-blocking tools that define the other two; some sync and customization limits may also matter.
What we like
- Free, with no ads or in-app purchases
- Groups and quick search for organizing contacts
- Contact backup and email-account integration
What to know
- No caller ID or spam-call blocking
- Limited contact-field customization and occasional sync issues
Best foridentifying unknown callers and blocking spam
Truecaller puts caller ID and spam-call blocking ahead of address-book management. It is the strongest fit here if screening unknown numbers and blocking scam or robocalls are your main priorities, and its 4.4 Google Play rating is the highest of the three.
It is free to download, but includes ads and offers in-app purchases from $0.99 to $449.00 per item. Its call identification and blocking depend on internet access for full functionality, and some legitimate calls may be misidentified.
