10 Best Free Call Blocker Apps for iPhone
Updated November 9, 2026 · written by AppHunt
On an iPhone, a call blocker app never answers the phone for you. Apple lets an app hand the Phone app a list of numbers through the Call Blocking & Identification setting; when one of them calls, iOS either shows a label such as a spam warning or stops the call before it rings, depending on what the app put on its list. Some apps mainly label, some block outright, and the carrier apps from Verizon and AT&T do part of the work on the network before a call reaches your phone. Every app below can be used free with no trial clock: either it sells nothing, or the developer states which protection comes without paying. Expect gaps all the same; spoofed numbers change daily, and no list catches everything.
Verizon Call Filter
Verizon's own filter for its wireless customers. The free tier flags suspected spam with an on-screen alert, sends high-risk callers straight to voicemail, keeps a log of what was stopped, lets you report numbers, keep an allow list and shut out up to five area codes or prefixes. It works only on a Verizon monthly or prepaid line, and Verizon is nudging users toward its broader Verizon Protect app, which now carries the same controls.
Good for: Verizon customers wanting network-level blocking
Keep in mind: Free for Verizon customers with a compatible device, according to Verizon; Call Filter Plus adds caller names, a neighborhood filter and more prefix blocks for $3.99 a month per line, or $10.99 a month for three or more lines, after a 15-day trial (US App Store, November 9, 2026; may change). October and November 2026 reviews are split: many say most junk calls are caught, others that spam still rings through and that the app keeps pushing Verizon Protect; one reports it blocked a home phone.

Hiya
Hiya pulls names and reputation data for numbers outside your contacts, labels incoming calls and blocks numbers that other users have reported. After a missed call you can look the number up, report it and review recent activity. The newer Call Screener, which answers unknown callers and asks why they are calling, and the AI voice detection bundled with it, sit behind the Premium plan and need call forwarding set up through your carrier, in the US and Canada only.
Good for: Basic caller ID and blocking on any carrier
Keep in mind: Hiya's site describes a Basic tier at $0 for good with caller ID, basic blocking and spam reporting; Premium is $3.99 a month, $9.99 a quarter or $24.99 a year and adds Call Screener, AI voice and fraud detection, premium lookups and advanced blocking, with a separate $2.99 Lookup Plan (US App Store, November 9, 2026; may change). Late-2026 reviews are mixed: long-time users still call it a lifesaver, while others say spoofed calls keep ringing, that the free number list shrinks after updates, or that it blocked a spouse.

YouMail
YouMail started as visual voicemail and still works that way: unanswered calls forward to its service, and known robocallers hear an out-of-service tone instead of your greeting, which teaches many autodialers to drop your number. It also labels unknown callers, filters scam texts and scans data-broker sites for your details. Setup takes longer than a plain blocker because it replaces your carrier voicemail, and reviewers say leaving later takes a few steps as well.
Good for: Stopping robocalls at the voicemail stage
Keep in mind: YouMail counts blocking of spam and robocalls, caller names on unknown numbers, protection from scam texts, a privacy scan and voicemail protection as free; paid plans add call screening that makes callers prove they are human, data-broker removal and a second number. Listed prices run from $9.99 a month for Plus to $144.99 for Essentials, with Complete at $24.99 and a $79.99 yearly Plus (US App Store, November 9, 2026; may change). Autumn 2026 reviews praise it as the app that finally worked, while others report charges they did not expect and trouble cancelling.

AT&T ActiveArmor
AT&T's security app pairs the carrier's network-level spam fight with device tools. For AT&T wireless lines the free part blocks fraud calls automatically, flags or blocks suspected spam, routes unwanted categories to voicemail, keeps a personal block list and sends breach and device alerts. The call features need an AT&T wireless account. The $7 Advanced tier is mostly identity protection, a VPN and safe browsing, not stronger blocking, although caller ID appears on both sides of the listing.
Good for: AT&T customers; blocking plus breach alerts
Keep in mind: AT&T says the mobile security service is free and lists automatic fraud and spam call blocking, call routing, a block list and alerts, noting the call features work only on AT&T wireless. ActiveArmor Advanced, $7 a month per line, adds caller ID, reverse lookup, public Wi-Fi protection, identity monitoring and $1M identity theft insurance (US App Store, November 9, 2026; may change). The US review feed returned no recent entries at the time of checking, so themes come from AT&T's own pages and the 4.5 average across 82,000 ratings.

Call Protect (Orave)
A small, no-frills blocker from the maker of Reverse Lookup. It loads a roster of known robocallers into the iPhone's blocking extension: numbers judged dangerous are stopped outright, while merely suspicious ones ring with a warning label. You can also search a US or Canadian number, block an entire range and paste numbers in from your call log. The app weighs about 10 MB and has changed little since 2019; the developer never spells out what the PRO tier adds.
Good for: Lightweight list-based blocking
Keep in mind: Orave calls it a free robocall blocker and says the PRO Protection subscription, listed at $2.99, gives features on top of the basic free ones without naming them (US App Store, November 9, 2026; may change). Its 2026 reviews are the weakest on this list: 24 of the latest 50 are one star, with themes of 'basic does nothing', a trial that billed about $119 for a year, and range blocking that let calls through; those who like it praise the spam banner on incoming calls.

RealCall
RealCall advertises AI call screening, but the part that costs nothing is narrower: the free tier labels incoming callers flagged as likely scams or spam risks, quarantines fraud texts into a junk tab with on-device filtering, and keeps your own block and allow lists. Automatic blocking of spoofed numbers, caller name lookups, an ad-free interface and family sharing need Premium, which begins with a trial. Reviews are unusually polarized, from miracle cure to unwanted charge.
Good for: Free spam labels; paid auto-blocking
Keep in mind: Per the developer, free features are alerts for callers flagged as spam or scam, fraud SMS detection and a custom block and allow list; Premium adds AI-powered advanced blocking, precision caller ID, no ads, custom voicemail greetings and a family plan, with a free trial for new users. Listed plans run from $5.99 a week to $79.99 a year, with $9.99 and $14.99 monthly options (US App Store, November 9, 2026; may change). October 2026 reviews: 'from 30 spam calls a day to 1' sits next to 'they don't understand what free means' and a $65 charge after a trial.

Simple Call Blocker
A two-megabyte utility from an independent developer that does one job: it hands the iPhone a list of numbers and number ranges to block. There is no spam database, no account, no ads and nothing to buy. You enter a nuisance number, an area code or a toll-free range such as 800-###-####, and those calls stop ringing; an allow list protects your contacts. The ceiling is iOS itself, which caps how many entries a blocking extension can hold.
Good for: Blocking whole area codes for free
Keep in mind: Nothing to buy: no in-app purchases are listed, and the developer says the app has no spammer blacklist and collects no data (US App Store, November 9, 2026; may change). Reviews from August to November 2026 split between five stars ('rare no-strings free app', blocking two million numbers in one range) and one star from people who hit the entry limit, wanted texts blocked too, or found that blocked calls still land in voicemail.

Call Blocker by UnknownPhone
This Call Blocker comes from the people behind UnknownPhone.com, a community site where users write up the calls they received. Switch protection on and the iPhone blocks numbers from the app's spam list, which you can extend with your own block list; look a number up to read other people's reports before calling back; report suspicious callers yourself. The free version shows ads and meters lookups with credits, and the full database with hands-off updates is a paid extra.
Good for: Crowd-reported spam list with readable reports
Keep in mind: The developer says the free app identifies and blocks numbers on its protection list and offers lookups and reporting; the optional subscription adds the full database for your country, automatic list updates and blocking, unlimited lookup credits and no ads. Plans are listed from $4.99 for one month to $22.99 a year, with three-month options at $9.99 and $14.99 (US App Store, November 9, 2026; may change). Reviews are few: 2026 five-stars in Portuguese and Spanish, a plain 'didn't work', and a late-2025 complaint that nothing was blocked until numbers were pasted in by hand.

Roblock
Roblock keeps a database of more than 800,000 US spam numbers, split by country, and lets you decide whether a match is merely labeled or blocked outright. Calls can be reported straight from the Recents list in the Phone app, your contacts can be whitelisted without leaving the device, and an SMS filter catches junk texts. Everything is free except the freshest list updates and neighbor-spoofing blocks. The app was last updated in June 2025 and has few recent reviews.
Good for: Label-or-block choice with a free list
Keep in mind: The developer says the app is completely free apart from premium features, which are the most recently updated blocking list and neighbor-spoofing blocking; premium subscriptions are listed at $2.99 and $23.99 with a 7-day trial (US App Store, November 9, 2026; may change). Only a handful of US reviews exist: five-stars from 2023 to April 2025 report that robocalls stopped, while one from November 2024 says it did nothing. Last updated June 4, 2025.

Phone Spam Pattern Blocker
Instead of blocking one number at a time, you write a pattern such as 833-XXX-XXXX and every number it matches lands on the iPhone's own block list, so an entire area code, exchange or neighbor-spoofing range stops ringing. A preview shows how many numbers a rule covers, exceptions keep chosen numbers ringing, and patterns sync through iCloud. The developer says the app cannot see your calls or contacts. Blocked callers can still leave voicemail; that is how iOS blocking behaves.
Good for: Blocking area codes and spoofed ranges
Keep in mind: Apparent Logic says patterns covering up to 5 million numbers are free, and that Pro, a one-time $4.99 purchase with no subscription, lifts the ceiling to 1 billion (US App Store, November 9, 2026; may change). Reviews are polarized and the 3.2 average is the lowest here: 'Actually free!!' (February 2026) and praise for silencing a whole area code (August 2026) sit beside complaints that blocked numbers still reach voicemail and the recents list (August 2026), and that covering every toll-free code needs the paid tier.

Questions and answers
What is the best free call blocker app for iPhone?
It depends on your carrier more than on the app. If you are on Verizon or AT&T, start with Verizon Call Filter or AT&T ActiveArmor: both are free for their own customers and stop part of the spam on the network before it reaches your phone. On any carrier, Hiya is the most-rated free call blocker app for iPhone that labels and blocks reported numbers without a trial clock, and YouMail is the pick if you would rather make robocallers hear a disconnected tone. For a best call blocker app that costs nothing and asks for no data at all, Simple Call Blocker and Phone Spam Pattern Blocker shut out whole area codes with one rule, though neither carries a spam list of its own.
How do I turn on a call blocker app on iPhone?
Install the app, open it once so it can download its number list, then go to Settings > Phone > Call Blocking & Identification (on recent versions the path is Settings > Apps > Phone) and switch the app on. From then on the Phone app checks every incoming number against the list the app supplied: numbers marked for blocking never ring, and numbers marked for identification ring with a label such as a company name or a spam warning. A call blocker app for iPhone cannot see or listen to your calls; it only hands iOS that list, which is why it still has to reopen now and then to refresh it. Carrier apps add network-side blocking on top.
Does iOS block spam calls on its own, without an app?
Partly, and for free. Settings > Phone > Silence Unknown Callers sends every number that is not in your contacts, recent outgoing calls or Siri suggestions straight to voicemail. Since iOS 17, Live Voicemail shows a transcript on screen while the caller is still talking, so you can pick up if it matters. iOS 26 adds Screen Unknown Callers, which answers the call silently, asks the person for their name and reason, and only then rings you. In Messages, Filter Unknown Senders does the same for texts. What iOS lacks is the knowledge of which numbers are spam, so legitimate unknown callers, a doctor's office or a delivery driver, get the same treatment as a robocaller; a spam call blocker app adds that judgment.
Are the carrier spam blockers free?
Mostly, for the carrier's own customers. Verizon says Call Filter is free on standard monthly and prepaid plans, with the Plus tier, $3.99 a month, adding caller names. AT&T says ActiveArmor's fraud and spam call blocking is free with every AT&T wireless plan; the $7 Advanced tier is mainly identity protection. T-Mobile's Scam Shield protection still exists, but its standalone app has not been updated since March 2025 and reviewers say it crashes and now lives inside the T-Life app, so it is not on this list. Xfinity Call Guard is tied to Xfinity Mobile's Premium Unlimited plan. None of these free spam call blocker apps work on a different carrier's SIM.
Why aren't Truecaller, Robokiller and Nomorobo on the list?
Because they do not meet the rule that blocking or identification must work free with no time limit. Truecaller's own App Store listing says a paid subscription is required to use spam identification on iPhone, and its Premium costs $9.99 a month or $74.99 a year. Robokiller sells only memberships, listed at $10.99 to $89.99, after a seven-day trial; recent reviews call it 'pay to play'. Nomorobo starts at $2.99 a month or $19.99 a year, and its Max tier at $59.99 a year. TrapCall, Call Control, Getcontact and Sync.me were left out for similar reasons, trial-only pricing, an unstated free tier or a stale app. A spam call blocker app for iPhone can be excellent and still not be free.
Do these apps block spam texts too?
Some do, through a separate iOS switch. YouMail and RealCall both list scam or fraud text filtering among their free features, and Roblock has an SMS filter you enable under Settings > Messages > Unknown & Spam. Hiya, Verizon Call Filter and AT&T ActiveArmor are focused on calls; reviewers of Hiya and Simple Call Blocker specifically ask for text blocking. iOS itself can sort texts from unknown senders into their own list for free. Dedicated text filters such as Textkiller or Bouncer are not in this spam call blocker app list because texts are their main job and both charge, Bouncer as a $9.99 purchase and Textkiller as a subscription.
Do call blocker apps upload my contacts?
Check the App Privacy label before you install, because the answers differ. Verizon Call Filter, YouMail, AT&T ActiveArmor and RealCall all list Contacts among data linked to you, so check each label. Hiya's label lists no contacts category, and its site says calls with people you know are never processed. Simple Call Blocker declares that it collects no data at all, Phone Spam Pattern Blocker says it has no view of your calls or contacts, and Roblock says contacts are whitelisted on the device. Crowd-sourced directories such as Truecaller and Getcontact are the apps that have historically made other people's address books searchable. A free spam call blocker app should not need your contacts to block a robocaller, so treat that request as a choice, not a requirement.
How is the list ordered?
Places 1–10 are ordered by the number of ratings each app has in the US App Store, one app per developer. Only apps whose main job is identifying or blocking spam calls on iPhone qualify, and only when the developer states that this works for free with no time limit; trial-only apps, apps that sell the blocking itself as a subscription and apps whose listing never says what is free were left out, as were lookup-only tools and apps abandoned for years. The count shows how many people use an app, not how much spam it stops: the two carrier apps lead because every Verizon and AT&T customer is pointed to them. No app of ours is on this list.
