Major version release 2.0 brings an entirely redesigned interface incorporating innovative suggestions from our users. If somebody called you or contacted you via social media and you're trying to find out who owns the number, use our app to quickly do a "reverse lookup" and determine who called you. New features in Version 2.0: -Global Caller ID now allows search of over 1 billion phone numbers worldwide! Our free version covers ~60% of numbers - the best free service available. -Maps Geolocation shows approximate area by area code. -All new Social Media directory to publish your Facebook, Twitter, Instagram and email addresses in our phone directory! -Crowdsourced voting and comments on SPAM numbers, prank callers, telemarketers, etc. -Dialing format and timezone gives you all the information you need on foreign / international contacts. Most (if not all) cellular phone carriers do not offer the full caller ID service that exists for landline phones.

Since 2013, Greenflight has offered this invaluable free & real caller ID utility for the iOS architecture. This tool may only be used to research phone numbers that called you or contacted you via social media. All use must comply with applicable international, federal, and local laws. The Caller-ID service is not a consumer reporting agency as by the Fair Credit Reporting Act. For Caller ID Pro Edition subscriptions, a free trial three day trial is available for first time users.

Verdict

The call

The clearest difference is review sentiment: Viva VPN at 88% against Caller's 42%. Viva VPN also leads on rating (4.5 vs 3.7) and update cadence (every 9 days vs every 5 weeks). Caller's advantage is ads (none vs shown) and iOS requirement (8.0 vs 15.0). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
