AdGuard and 1Blocker are the two most-installed content blockers on iOS. Both do a solid job on general web browsing. Both are advertised as "podcast ad blockers" in some corners of the internet. Neither is really that, and understanding why is the first useful thing to know before you pay for one.
This comparison walks through what each tool does with podcast ads specifically, what neither of them can do (regardless of price), and which one to pick if you're an iPhone user looking to reduce your podcast ad load in 2026.
The short version
- Both AdGuard and 1Blocker are Safari-extension-based on iOS. Neither can touch native app content.
- Podcast ads inside the Apple Podcasts app, the Spotify app, or any other native podcast app are invisible to both tools. The apps deliver their ads inside their own audio streams, which iOS Safari extensions cannot inspect.
- Both tools do help if you listen to podcasts in Safari (via the show's web player). AdGuard's DNS mode (AdGuard Pro) is the more capable option there.
- If your goal is to reduce podcast ad load, the answer is a different podcast app, not a content blocker. This is one of those cases where the right tool is not the one you searched for.
What content blockers on iOS can and can't do
Apple's content-blocker framework, introduced in iOS 9, is designed for Safari and for web content only. A content-blocker extension can:
- Block requests to specific domains (ad servers, tracking pixels).
- Hide specific DOM elements on a page (banner ads, popups).
- Rewrite requests (e.g., strip tracking parameters from URLs).
A content-blocker extension cannot:
- Inspect or modify content inside any native app (Apple Podcasts, Spotify, YouTube Music, or any third-party podcast app).
- Intercept traffic that doesn't go through Safari.
- Access encrypted audio streams inside a native player.
That's the framework. AdGuard and 1Blocker both operate within it. Neither has a magical extra capability.
The one exception is AdGuard's DNS-level product (branded AdGuard DNS or AdGuard Pro on iOS), which sets up a system-wide DNS proxy that catches all outgoing DNS requests, including from native apps. This can block requests to known ad-server domains from any app on your phone, not just Safari. That's a meaningfully broader capability than the Safari-extension mode, and it's the closest either of these tools gets to touching podcast ads.
Even AdGuard Pro's DNS mode, however, doesn't help with dynamic ad insertion. If a podcast's ad audio is stitched into the same file as the show audio server-side (Spotify's approach, and increasingly the industry default), there's no separate DNS request to catch. The ad is inside the audio file, and DNS blocking never sees it.
AdGuard on iPhone
What you get
AdGuard on iOS comes in two forms.
AdGuard for iOS (free) is a Safari content blocker with a well-maintained filter list. Blocks display ads, tracking pixels, and cookie popups across the web. Works only in Safari.
AdGuard Pro (~$1.99/mo or one-time purchase) adds the DNS-level blocker described above, plus advanced Safari filtering. The DNS proxy catches ad-server domains from all apps, not just Safari.
How it does on podcasts
Native podcast apps (Apple Podcasts, Spotify, Pocket Casts, Overcast, etc.): essentially no impact on the audio ads themselves. AdGuard's Safari component can't reach them. AdGuard Pro's DNS mode can theoretically block some tracking calls the app makes, but the ad audio itself is either baked into the show (host-read) or stitched via DAI (programmatic), and DNS blocking can't intercept the audio inside either case.
Web-player podcast listening (via Safari): AdGuard cleans up the podcast pages on Apple Podcasts web, Spotify web, YouTube Music, and third-party web players. Display ads and tracking are blocked. Pre-roll video ads on YouTube podcast pages are largely blocked (though YouTube pushes back against ad blockers regularly, so this is an ongoing arms race). Audio spot ads inside the podcast stream itself still play.
Verdict
Solid general-purpose iOS content blocker. Best-in-class Safari filtering. AdGuard Pro's DNS mode is the closest iOS gets to a system-wide ad blocker without jailbreaking. For podcast ads specifically, it doesn't do much, because podcast ads mostly live outside its reach.
1Blocker on iPhone
What you get
1Blocker is a purely Safari-extension-based content blocker. It's app-installed (not a browser extension in the desktop sense), which is how iOS handles content blockers. There is no DNS-level product; 1Blocker is Safari-only.
1Blocker uses a "package" model where you can enable or disable specific filter categories (ads, trackers, adult content, comments, social widgets, etc.). It's known for a tight, well-organised UI and strong emphasis on user control over what gets blocked.
Free tier is limited. Full functionality unlocks with a one-time purchase or subscription (~$3/mo).
How it does on podcasts
Native podcast apps: no impact. Same limitation as AdGuard's Safari component. iOS content blockers cannot reach native apps.
Web-player podcast listening: comparable to AdGuard for basic Safari cleanup. 1Blocker's filter list is smaller than AdGuard's overall, but well-curated, and blocks the same class of display and tracking content on podcast pages.
Verdict
Well-designed Safari content blocker with strong user-controllable filter categories. Doesn't have AdGuard's DNS-mode advantage, so its reach doesn't extend beyond Safari at all. For podcast ads specifically, it's in the same "not really the right tool" bucket as AdGuard.
Head to head on podcast use cases
| Use case | AdGuard (free) | AdGuard Pro | 1Blocker |
|---|---|---|---|
| Ads inside Apple Podcasts app | No effect | No effect | No effect |
| Ads inside Spotify podcast (DAI programmatic) | No effect | No effect | No effect |
| Ads inside third-party podcast apps (Overcast, Pocket Casts, etc.) | No effect | Minimal (some tracking) | No effect |
| Podcast pages on Safari (Apple Podcasts web, Spotify web) — display ads | Blocked | Blocked | Blocked |
| Podcast pages on Safari — pre-roll video ads | Mostly blocked | Mostly blocked | Mostly blocked |
| Podcast pages on Safari — audio spot ads inside stream | Not blocked | Not blocked | Not blocked |
| Tracking calls from native podcast apps | No effect | Some blocked at DNS | No effect |
Neither one is a "podcast ad blocker" in the way the phrase suggests. Both are competent Safari content blockers that also cover podcast pages when you happen to browse them in Safari. AdGuard Pro's DNS mode is the only feature in this comparison that extends beyond Safari at all, and even that doesn't touch podcast audio.
What actually reduces podcast ads on iPhone
If reducing podcast ads is the goal, the effective route is a different podcast app, not a content blocker.
Podcast apps that give you more control over ad exposure fall into three broad camps:
- Apps with silence detection and smart skip-forward controls. Overcast's Smart Speed is the best-known example, and several other modern podcast apps ship equivalent "silence trimmer" features. These don't specifically target ads, but they trim dead space and make manual skip-forward-30-seconds more productive during ad breaks. Overcast also has Voice Boost, which helps with the ad-vs-show loudness gap discussed in our why podcast ads are getting louder guide.
- Apps that support ad-free member feeds well. Most podcast apps let you paste in a private RSS URL you receive when you support a show on Patreon or via a similar membership. If your favourite shows offer ad-free versions to supporters, any decent third-party app will let you subscribe to those feeds.
- Apps that pull the show directly from its public RSS feed rather than through Spotify's DAI overlay. Any modern podcast app that speaks RSS (Apple Podcasts, Overcast, Pocket Casts, AntennaPod, Podverse, Castro, and several others) will deliver a show without whatever programmatic ads Spotify would have layered on top. The show still has whatever host-reads the creator baked in, but you skip the DAI-inserted spots entirely.
Combining any of the above with an iPhone-level accessibility setting like Reduce Loud Sounds (Settings > Accessibility > Audio & Visual > Headphone Safety) gets you most of the way to a comfortable listen.
When AdGuard or 1Blocker is still worth installing
Both are useful iOS apps, just not for the podcast use case they sometimes get pitched for. If you already use Safari a lot for general browsing, one of them (probably AdGuard given its DNS-mode advantage) is worth having installed for the general web-cleanup benefit. That's the correct use case.
If your only goal was to stop podcast ads on your iPhone, neither AdGuard nor 1Blocker was going to get you there, and it's better to know that up front than to buy a subscription and discover it afterward. The iOS content-blocker framework simply doesn't extend to the places where podcast ads live.
Frequently Asked Questions
Can AdGuard block Spotify podcast ads on iPhone?
Not the audio ones. Spotify uses dynamic ad insertion, which stitches ads into the podcast audio server-side. AdGuard's Safari component doesn't touch the Spotify app at all. AdGuard Pro's DNS mode can block some tracking calls the Spotify app makes, but not the ad audio itself. This is a limitation of the iOS content-blocker framework, not of AdGuard specifically.
Does 1Blocker work on the Apple Podcasts app?
No. 1Blocker is a Safari extension only. It cannot reach any native app, including Apple Podcasts.
Is AdGuard Pro worth it over free AdGuard for podcasts?
For podcast ads specifically: no, the difference is minimal because neither product can reach where podcast ads live. For general iPhone use: yes, the DNS-level system-wide blocking is a meaningful upgrade over Safari-only filtering, especially for ads and trackers inside other apps.
What actually blocks podcast ads on iPhone?
No content blocker does, because podcast ads on iPhone live inside native apps (out of Safari's reach) or are stitched into podcast audio via dynamic ad insertion (invisible to network-level blockers). The realistic path to fewer podcast ads on iPhone is a podcast app with strong skip controls and silence detection, or ad-free member feeds where your favourite shows offer them.
Are there any iOS apps that actually block podcast audio ads?
A handful of apps promise real-time podcast ad detection and skipping. In practice, most don't work reliably because ad detection in audio is a hard signal-processing problem, and false positives (muting parts of the show) are common. The more sustainable approach is choosing podcasts that offer ad-free member feeds and using a modern podcast app that gives you fast skip controls for the ones that don't.
