Format matters on some sites.<\/p>\n<h2>What About Apps?<\/h2>\n<p>Some of these services also offer handy apps. Truecaller and Spy Dialer, for example, have apps for iOS and Android. That way, you get caller info right when the call happens. Very James Bond.<\/p>\n<h2>How Accurate Are These Sites?<\/h2>\n<p>Let\u2019s be real\u2014no site is 100% accurate all the time. Numbers change hands. People move. But most of these services will at least tell you if it\u2019s spam, a company, or a real person.<\/p>\n<p>Accuracy depends on:<\/p>\n<ul>\n<li>How often the site updates data<\/li>\n<li>User contributions (especially for scam calls)<\/li>\n<li>Public records availability<\/li>\n<\/ul>\n<h2>Who Should Use Them?<\/h2>\n<p>Honestly?
