Types of Ads That Can Be Blocked:
• Website ads: Ads on domestic and international mobile and desktop sites.
• Tracking ads: Ads that track your search information.
• Embedded ads: Ads cleverly inserted in the middle of articles.
• Popup ads: Ads that appear in a popup format.
• Forced redirect ads: Ads that forcibly redirect you from a site.
• Unnecessary SNS elements: Social media comments and share buttons.
• Cryptocurrency mining scripts: Blocks illegal mining scripts.
• Anti-adblock circumvention ads: Ads that bypass ad blockers.
• Video ads: 5–15 second video ads
(Ads on some sites that are beyond Safari’s content blocking capabilities may be difficult to block)
• Screen cleanup: Removes any blank spaces left after ad removal.
• Cleaner function: Allows users to directly select and remove content areas on sites where blocking is insufficient.

※ If ads are not completely blocked, please report them using the “Report Ad” feature within the app and we will respond accordingly.

Cleaner Function:
• Allows deletion of user-specified areas.
• Run the cleaner within the app or select Cleaner via Safari’s share button.

How to Update the Blocking Database:
• Press the update button after launching the app.
• Enable automatic updates within the app (background refresh required).

Frequently Asked Questions (FAQ):
• What if ads still remain?
Some video sites, Twitter, Facebook, or sites with anti-adblock measures may not have ads blocked.
→ In this case, using Unicorn Pro will resolve most issues.

• Does it block ads in apps or game apps?
This app is for the Safari browser only and does not block ads within other apps.

• What if ad blocking isn’t working well?
If ads are not blocked at all, please refer to the in-app guide to check if the settings are correct.
If problems persist, please uninstall and reinstall the app.

• What should I do if I see an ad?
In case of sudden ad appearance, please check if you can update to the latest blocking rules.

• Can ad blocking sometimes fail?
Since many sites frequently add or change ads, complete blocking may be difficult.

Notice:
※ In cases beyond the technical scope of the extension, some ads (such as on video sites, Twitter, Facebook, or sites with anti-adblock measures) may not disappear. In such cases, using Unicorn Pro will resolve most issues.

### 1/5 — Offline Impossible

*2026-04-10, version 1.27.7*

Application inutilisable en hors ligne et tentative de connection au serveur a chaque fois que l’application repasse au premier plan sans même avoir été fermée.
C’EST INSUPORTABLE !!!

The app is unusable offline and tries to connect to the server every single time it's brought to the foreground, even if it wasn't closed.
IT'S UNBEARABLE !!!

### 3/5 — オンオフが欲しい

*2026-03-19*

設定ではなく、アプリ自体はオンオフをワンタッチでできるスイッチが欲しいかな。起動したら一目でわかる見やすい所に置いて欲しい

### 1/5 — 과거엔 좋았으나 지금은 안쓰는게난듯

*2026-02-13, version 1.27.5*

어느순간부터 사파리 버벅임이 심해지다 3g속도만도 못해지고 뒤로가기해도 멈추는등 별의별 증상이 나옴. 별짓을 다하다 유니콘 끄니까 정상작동

### 5/5 — Ios26업데이트

*2025-10-18, version 1.27.1*

다좋은데 ios26 업데이트 이후에 작동을 안해요

### 5/5 — ios26 대응 업데이트 요청

*2025-09-16, version 1.27.1*

### 5/5 — Best

*2025-08-29*

Best app for block anything

### 5/5 — 광고 시대에 팔요한 최고의 앱

*2025-07-31, version 1.27.0*

저는 이 앱을 자주 접속해야만 하는 포털 메인에 보고싶지 않은 블럭을 지우는 데 활용하고 있습니다. 어느 순간부터 메인에 숏폼이며 자극적인 기사들이 떠서 눌러보게 되던걸 이 앱 기능으로 다 안뜨게 지운 뒤 온라인 탐색이 쾌적해졌어요. 또 너무 자주 접속하는 SNS, 커뮤니티 웹 접속을 차단하여 스스로 키즈락 걸듯 활용하기도 하고요. 그만하려고 앱을 삭제해도 너무 자주 웹으로 접속해서 시간 버리는 건 비슷했는데 이젠 온라인에 필요한 만큼, 내가 선택한 만큼만 머무르게 되었어요. 좋은 앱 오래오래 서비스 해주세요. 정말 감사합니다.

### 5/5 — 수명이 다했네요

*2025-06-07, version 1.25.26*

슬슬 앱의 수명을 다했나봅니다
그동안 사파리 유튭용으로 잘 썼습니다

### 4/5 — 좋습니다만..

*2025-06-03*

잘 쓰고 있었지만 최근 사파리에서 유튜브 재생시 매번 광고차단 앱 사용은 허용되지 않는다는 팝업이 뜨네요..

### 4/5 — 사파리에서 접속한 유투브에서 작동 안되나요?

*2025-05-22, version 1.25.26*

한국에서는 되던데..?
