Not good anymore

Used to be a good browser, but new features make it hard to use.

Charming

Nice charming browser, I like the scrapbook thing, useful for saving images :)

The new design is terrible. Looking for a new app.

Bad

Worst update ever

The new update is terrible. It’s so slow opening and closing tabs. I wish I had kept the old version. Please fix it.

They had it perfect until the new design ruined everything

The new UI is convoluted, bloated, hard to navigate and vastly different from the old design for no apparent reason. As a user from iPhone 4 the new design made me uninstall.

Poor Transition Planning & Questionable Redesgin

Data conversion is still broken as of 11/11/25. Left phone on “processing” screen, no visible progress after 30 minutes of continuous on screen time.

They ruined it

This used to be such a great browser. They changed everything to make it super confusing. And my bookmarks are gone!!! Worst update to any app EVER!

What happened with this new update

Have been using this app for over a decade. This new update is terrible. How do I search the current page? Where are my favourites? It also chugs now. Please revert to prior version and bring back swipe to change tabs - this is unusable.

New Version is awful

I’ve been using this app since 2011! Best browser out there! This new version is terrible PLEASE allow us who prefer it to download the old version…I CANT LIVE MY LIFE!!!

Unusable now

Best browser for tab management is now unusable after new update. Everything lags so much and crashes all the time. Don’t want scrapbooks. Bring back the original tab groups at the bottom. I wish I kept old version and didn’t update :(

Difficulty level: 9

I’m not sure what the new design is supposed to accomplish, but they difficulty of using this app has shot up by a magnitude. It’s now quite difficult tk switch between tabs, requiring several more steps than before. Scrolling through tabs result in tabs closing. I’m not even sure if switching between tab groups is doable without going through a menu.

What used to be a great application for managing and maintaining groups of websites is now… unrecognizable.

I won’t yet delete the app in the hopes that these changes are reverted. But if this stays, I’m not sure what this app has become.

It would have been much better for the developers to simply submit a totally different app with a new bundle ID than destroy this one they’ve had for years now.

I just need a browser, not a stupid scrapbook.

This new function is totally useless. Not to mention that many useful gesture control or full screen setting are missed. Worst update ever.

Horrible Update

The new UI is terrible. Horrible layout and quite laggy too. I have used this browser since 2011 instead of Safari. Now I will be switching if changes are not made soon. There needs to be an option to use the old user interface. I don’t want a “new modern” layout. I want the good light old reliable browser I’ve used for 15 years.

Simple & magical

Life saver. If you want to browse between large amount of pages like an archive or compare many pages nothing comes even close

タブ操作

iPhone13で、タブを閉じる操作がやりにくくなった。アプリ切り替えを誘発してしまう。
以前は気にならなかったから、ここ数日のアプデかな。

best tablet browser

this is the only tablet browser I can use comfortably on my tablet using gestures. don't have to reach all the way to the top to close or switch tabs

Shortcuts integration

I am a huge fan of this browser but the one thing holding me back is that when I send pages to Shortcuts via share extension the way The browserpasses the url causes an error

SUPERB BROWSER

With a pristine ad-block feature, the Sleipnir (pronounced as “Slay-Pea-Nir”) browser has everything a usual browser offers but is MUCH MORE FASTER and EASIER TO USE!

Clipboard Theft

This app collects your clipboard data. Beware.

User Agent

This app lets me do steaming if I change the user agent up a little bit
