The only way to see the site is to turn off the content blocker. Time to find a new ad blocker. ### 2/5 — No longer working properly *2026-07-09, version 1.3* The app appears to no longer work correctly in iOS 26. It does block some content but the whitelist doesn’t seem to work anymore. ### 4/5 — Blocks everything but YouTube *2024-08-13* Works perfectly with regular websites. Do not work on YouTube ### 1/5 — It’s not working anymore *2021-12-07* All settings are ok but it’s not working anymore ### 1/5 — Doesn’t work *2021-09-06, version 1.3* Loads of ads trickling through now as compared to when I originally started using I guess they have sold out ? Don’t waste your money Deleted & now looking for something that works ### 1/5 — On ipad 4 not work *2021-08-18* In the description it is written that it supports ipad 4, in fact does not support. Threw 50 cents to the wind… ### 1/5 — No longer works *2021-07-24, version 1.3* Years ago, when this app was first introduced, it worked. It hasn't worked correctly the last 2 years that I have tried using it. No updates, nothing. A forgotten app. ### 1/5 — Реклама! *2021-05-21* Реклама все равно лезет! Программа-то платная, какого все равно пропускает из?! ### 2/5 — Doesn’t block enough ads *2021-05-04, version 1.3* Does NOT block enough ads. There’s an option for “acceptable ads” but it disregards the setting as Google ads always seem to bypass this option. Please add adblocking within apps. ### 1/5 — Used to work *2021-05-04, version 1.3* Don’t bother ### 1/5 — Grosse arnaque et appli inutile *2021-05-03* Tout est dit dans le titre: l’appli ne sert absolument à rien et payer pour avoir rien est purement et simplement du vol et de l’arnaque! A éviter si vous ne voulait pas devenir un pigeon ### 2/5 — New installs won’t work *2021-01-29, version 1.3* If you already had this app installed years back it will still work. However, if you try to open it to change setting (add to the white list, for example) or open it for the first time the app will crash. ### 1/5 — No longer works as of Jan, 2021 *2021-01-04, version 1.3* The app doesn’t load, or block ads anymore ### 1/5 — Dead *2020-12-28, version 1.3* Won’t even open. iPhone XR & iOS 14.3 ### 1/5 — Worthless *2020-11-10, version 1.3* Looks like developers abandoned application, no any updates , don’t do anything except money at the beginning-deleted ### 1/5 — Flat out doesn’t block any ads. *2020-10-02, version 1.3* It just doesn’t work, at all. ### 1/5 — Just deleted *2020-07-19, version 1.3* Lately this app still blocks sites that have been added to the whitelist. It’s also clear that the developer gave up on the app years ago, so this is not an app you should download. I’ve just deleted it and will be looking for a replacement. ### 1/5 — Obsolete? No support? No updates for 3yrs *2020-07-11, version 1.3* And no mention of v2.0 release anywhere. Couldn’t tell you if it working any more. ### 1/5 — Where’s the update *2020-06-22, version 1.3* About time the block list gets an update ## Most critical reviews (10 lowest-rated) ### 1/5 — Do not buy *2024-10-25, version 1.3* No dev support for years. Does nothing. I regret buying this. ### 1/5 — かえって広告がでる *2024-10-22* ここ最近アドセンス系広告がいきなり出るようになり、こちらを削除したら消えました… ### 1/5 — waste of money *2024-02-27, version 1.3* cant believe i paid money for this. it does nothing ### 1/5 — Totally broken *2023-10-23, version 1.3* Blocks every single website now ### 1/5 — Crystal link to Twitter *2023-08-18, version 1.3* This app not only did not function as Malware, it installed “X” on my iphone. Ingregious and repetitive ads sold and promoted by Google were and-are—continuous. This app is a rip-off! ### 1/5 — Stopped working years ago. Zero updates! *2023-07-11, version 1.3* Avoid. The developer hasn’t supported this app in many years. Doesn’t stop anything anymore. Complete waste. ### 1/5 — Application morte *2023-03-07* Plus de mise à jour, ne sert plus à rien ### 1/5 — Abandoned. Nonfunctional. Wasn't great to begin with. *2022-11-27, version 1.3* UPDATE: I no longer recommend Crystal at all. It has been abandoned for many years. Likely it was abandoned immediately after it was created. The block list is ancient to the point of being irrelevant. Every single ad I reported to the developer since the app was released years ago never got added to the blocklist. Any updates to the blocklist provided since release have long since stopped years ago. The final release of the app merely added an "acceptable ads" feature: that is, enabling even more ads to get through its already weak defenses. ### 1/5 — No Longer Works *2022-11-13, version 1.3* Worked fine and still blocked most ads for me. The n the last few weeks it stops working on Google search (prevents me from searching and blocks the click through url) ### 1/5 — Long gone *2022-07-10, version 1.3* Was good while it lasted. Looks like the app and website have been abandoned ## Most praised reviews (10 highest-rated) ### 5/5 — Excellent *2020-07-14, version 1.3* Excellent - I don’t know why I even bother checking Crystal once a fortnight , it always works well with absolutely no fuss, unlike it’s competitors ### 5/5 — Works as advertised *2019-09-05, version 1.3* The poor reviews here may be because the users have failed to install the app correctly, and make the necessary, one-time tweak to ensure it’s operating effectively. ### 5/5 — Last update 2 years ago *2019-08-12, version 1.3* It was once a great adblocker but the developer has stopped all the updates and now it it obsolete. There are much better alternatives on the market while this is getting behind everything. ### 5/5 — Installed 7/30/2019 *2019-07-31, version 1.3* This blocker works for me! After installation I pulled up 4 sites that had the most obnoxious flashing ads, and they’re gone! To me worth 10 times the price. ### 5/5 — Crystal *2019-06-24, version 1.3* It works!!!!!! ### 5/5 — 1er jour d’utilisation et rien à redire *2019-06-16* Premier jour d’utilisation et rien a redire. Finies, enfin, les pop-up qui vous forcent à fermer votre page pour les faire dégager, ou ceux qui prennent 80% de l’écran. 1€ bien investi ! Je recommande ! J’étais harcelée par les tentatives d’escroqueries dans safari, me voilà à nouveau en paix. ### 5/5 — Still works, people are just morons *2019-05-22, version 1.3* Been using it since it first came out. I downloaded AdBlockPlus and Purify as well, stuck out with Crystal since that is the only one that still worked after a year. Today, in mid 2019, Crystal still works. I don’t know what other people are doing that they think it isn’t working. I expect ignorance. ### 5/5 — Still excellent *2018-10-31, version 1.3* This app still works great for me - it blocks all ads on all sites, and doesn’t break any sites. ### 5/5 — Crystal App *2018-10-30, version 1.3* The app worked great but beware . . It will mess up your settings on any apple phone! Still can’t get one of my emails even though I deleted it! ### 5/5 — Excelente *2018-10-15* Depois de anos usando a gente deixa a resenha. Instala e esquece, ele funciona sem estresse. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
