Our picks for the most effective spam call blocking apps
Call blocking apps add an extra layer of protection beyond what your carrier provides. Here are the most effective options for 2026.
Truecaller's community-powered database of over 2 billion numbers makes it one of the most comprehensive caller ID services. The free tier includes caller ID, spam detection, and manual blocking. Premium ($2.99/mo) removes ads and adds advanced spam filtering, call recording (where legal), and an "incognito" mode that hides your profile from searches.
RoboKiller ($4.99/mo) uses AI to identify and block spam calls, but its unique feature is "Answer Bots" — AI that answers scam calls and wastes the scammer's time with realistic conversation. This actually hurts scam operations by consuming their resources. It blocks over 99% of spam calls in testing.
Nomorobo ($1.99/mo for mobile, free for VoIP landlines) uses a patented "simultaneous ring" technology for landlines. It answers spam calls before your phone rings, so you never hear them. For mobile, it provides real-time spam screening with one of the lowest false-positive rates.
Hiya's strength is caller identification. Even for numbers not in your contacts, Hiya can often identify the business or person calling. The free tier handles basic spam detection; Premium ($3.99/mo) adds enhanced caller ID and automatic spam blocking.
T-Mobile Scam Shield is automatically enabled and surprisingly effective. AT&T ActiveArmor provides good baseline protection. Verizon Call Filter offers spam risk ratings for each call. These are worth enabling even if you also use a third-party app.
For most people: enable your carrier's free protection, then add Truecaller (free) for enhanced caller ID. If you want maximum protection and don't mind a subscription, RoboKiller is the most aggressive blocker available. For landlines, a hardware call blocker outperforms any app.
