The best robocall blockers in 2026

The short answer: your carrier's free tool first, Nomorobo if you want more, and a clear-eyed look before anything else. This market is full of apps charging subscription prices for what the network now does free — so this ranking starts with the option that costs nothing, and among the paid apps it rewards published pricing and clean data practices. Everything verified on the date above; where a vendor hides its prices, we say so instead of guessing.

#1 — Your carrier's free tool (seriously)

AT&T ActiveArmor, Verizon Call Filter, and T-Mobile Scam Shield work at the network level: they use call-authentication data to kill or label scam calls before your phone rings, which no app can do from the handset. FCC guidance and independent testing consistently conclude the free tiers are sufficient first-line protection for most people. Setup for all three carriers is in our stop spam calls guide — do that before spending a dollar here.

#2 — Nomorobo: the transparent one ($19.99/yr)

Nomorobo Basic costs $2.99/mo or $19.99/yr — published in plain text on its pricing page, which in this market counts as a personality trait. It blocks against a live database of 11M+ known robocallers, the Max tier ($59.99/yr, T-Mobile/Verizon/AT&T only) adds screening and spoof protection, and a Family plan covers four devices for $79.99/yr. Pedigree: it won the FTC's 2013 Robocall Challenge. One big 2026 caveat: the famous free landline/VoIP tier shut down January 1, 2026 — landline users need a new plan. Full disclosure: Nomorobo has no affiliate program, so this top pick pays us nothing. That is rather the point.

#3 — YouMail: the free tier that's actually useful

YouMail attacks robocalls at the voicemail layer: it replaces your carrier voicemail, checks callers against its network-wide database, and plays known robocallers an out-of-service tone so autodialers mark your number dead and stop calling. The base tier — spam blocking, visual voicemail, caller ID — is free; paid plans (roughly $5.99/mo billed annually — their site blocks verification, so confirm at signup) add capacity and business features. Two honest caveats: you are handing your voicemail to a third party, and YouMail analyzes voicemail audio at scale to build the robocall index it also sells commercially. YouMail is the strongest free starting point if your carrier tool isn't enough.

#4 — RoboKiller: the most weaponized, the least transparent

RoboKiller's audio-fingerprinting engine and its signature Answer Bots — recordings that pick up scam calls and waste the caller's time — are genuinely effective and genuinely fun. It won the FTC's 2015 robocall-blocking challenge. The problem is the checkout: prices are not published in static pages and reportedly vary by signup channel (expect roughly $40–$70/yr; user reviews recur on this exact complaint). If the answer-bot revenge fantasy is worth it to you, take the 7-day trial via RoboKiller and screenshot the renewal price at checkout.

#5 — Truecaller and Hiya: know the trade

Truecaller (free; Premium $9.99/mo / $74.99/yr per its App Store listing) has the largest crowdsourced caller-ID database — about 450M users — and that is exactly the issue: outside the EU it has historically built that directory partly from users' uploaded contact books, putting people who never consented into the database, and Sweden's privacy regulator opened an investigation into its practices in February 2025. A spam-fighting tool shouldn't run on other people's leaked address books; we can't rank it higher. Hiya (free; Premium pricing unpublished) makes a solid engine — but it already powers Samsung Smart Call and several carrier filters, so check whether your phone is running Hiya before paying for Hiya.

The comparison, compressed

Option	Price (verified?)	Signature capability	The catch
Carrier tools	Free (official)	Network-level blocking before the ring	Paid tiers mostly unnecessary
Nomorobo	$19.99/yr (verified on-site)	11M+ robocaller blocklist, transparent pricing	Landline tier dead since Jan 2026
YouMail	Free tier (paid ~$5.99/mo, unverified)	Voicemail-level screening, "dead number" tone	Your voicemail lives with them
RoboKiller	Unpublished, ~$40–70/yr	Answer Bots + audio fingerprinting	Channel-dependent pricing
Truecaller	$74.99/yr (App Store)	Biggest caller-ID database	Database built from users' contacts; regulator scrutiny
Hiya	Unpublished	Engine behind Samsung/carrier filters	You may already have it

Whatever you install, remember what an app can and cannot do: it can screen the calls that reach your number. It cannot shrink the number of lists your number is on — that pipeline runs through the data brokers selling it, and shutting it down is a different, more permanent project.
