3. Reverse Lookup

Download: Android iOS

Reverse Lookup is a handy app to find unknown callers, offering valuable information like carrier, line type, and location—a significant improvement over previous apps I've tried. While it doesn't always reveal the owner's name, the additional location data is helpful in identifying potentially suspicious numbers. Unlike other services that try to trap you into subscriptions, this app provides core functionality for free, although some features could be improved (like a more intuitive copy-paste function). Despite limitations affecting some users due to external security issues, I chose this app for its balance of free features and useful location data, making it a better alternative to subscription-based people finders.

Key Features:

• Identifies unknown numbers and their location.
• Provides caller information including name and address.
• Reveals carrier and phone type details.

4. Eyecon Caller ID & Spam Block

Download: Android iOS

Cost: Free Plan (Free), Premium Plan (Annual) ($9.99/year)

Eyecon Caller ID & Spam Block is an app to find unknown callers, leveraging Facebook profile pictures to identify contacts—though accuracy is reported as only around 50%, sometimes linking to incorrect profiles. While praised for its full-screen caller ID and intuitive design on Android, users have reported issues with SMS verification codes on iOS, hindering full functionality. Its lack of robust spam blocking compared to other similar apps is a significant drawback. Ultimately, whether you choose Eyecon depends on prioritizing its visually appealing interface and caller ID features versus the need for comprehensive spam blocking and reliable cross-platform functionality.

Key Features:

• Identifies unknown callers with photos.
• Displays caller information before answering.
• Provides social media links for callers.
