Safari on the iPhone Duo's outer display keeps its controls in a strip down the side, and web pages stop short of it. Sidefill gives that strip back to the page. EDGE TO EDGE Phone-width pages are laid out across the whole outer display, right under Safari's side controls. Articles, photos and video get the room the screen already has. STILL TAPPABLE Links, menus and buttons that would land under the controls move back into reach. Fixed headers and tab bars carry their color to the edge while their contents stay clear. An optional blur keeps the controls readable over busy pages. ONE SWITCH Choose Wide or Off from Safari's page menu. The choice applies to every site and tab, and any single site can be left as it is with one tap. Desktop-width pages are never touched; they look exactly as Safari shows them. PRIVATE BY DESIGN No account, no analytics, no network requests. Sidefill adjusts layouts on your iPhone and never reads or sends what you browse. ONE PURCHASE Buy it once and keep it. No subscription, no in-app purchases. SETUP 1. Settings › Apps › Safari › Extensions › Sidefill 2. Turn on Allow Extension and set All Websites to Allow 3. In Safari, open the page menu › Sidefill › Wide Sidefill is made for the iPhone Duo. On other iPhones Safari already uses the full width, so there is nothing for Sidefill to change. ## Key features - Full-width page layout on outer display - Repositions links and buttons - Allows fixed headers/tab bars to edge - Optional blur under controls - One-switch toggle for wide browsing - Private browsing with no analytics ## Chart rankings - #62 in Top Paid · Utilities (US App Store) ## Is Sidefill safe?

The only way I can get it to work is to turn it completely off under the advanced fingerprinting, whatever settings the developer suggested, but I don't wanna leave that setting off... ### 5/5 — wonderful *2026-11-10* nice ### 1/5 — Doesn’t Work! DON’T BUY!!! *2026-11-09* Doesn’t do anything. Does not work at all. Buy Brim Browser (by another developer) instead. That one actually works. It’s a standalone browser but also comes with a safari extension that does exactly what this app claims it does. **Developer response:** Thanks for the report, and sorry Brim didn't work for you. We found the cause: when Safari's Advanced Tracking and Fingerprinting Protection is set to All Browsing, Safari hides the Duo's real screen size, so Brim can't tell it's on a Duo and stays off. We're fixing this, and the fix is in the next version (now in App Review). Until then, set Settings › Apps › Safari › Advanced › Advanced Tracking and Fingerprinting Protection to Private Browsing, and Brim will work in regular tabs. ### 4/5 — 重なったりして使いにくくなる事もあるけど総合的にはいい！ *2026-11-09* 結論から言うと価格的に買った方がいいです！おすすめです。 タイトルどうりiPhoneDUOは右にバッテリーやWi-Fiマークがあるのでそれとサイトのボタン（メニューボタンなど）が重なって少し使いにくくなる事もありますが、普段サイトを見る時にフル画面で見れるのはかなりいいです！ たまにサイトをスクロールしてると画面がバグ？って通常のサイト表示右側が開いてるやつになることがありますのでそこはアプデに期待しましょう。 ### 3/5 — Not bad *2026-11-09* Works similar to wider app except no ugly extra button and cheaper. Although not all websites work. Not sure why, but if they can be fixed it would earn a higher rating. ### 1/5 — Doesn’t work *2026-11-08* Enabled as instructed but doesn’t work as promised. **Developer response:** Thanks for the report, and sorry Brim didn't work for you. We found the cause: when Safari's Advanced Tracking and Fingerprinting Protection is set to All Browsing, Safari hides the Duo's real screen size, so Brim can't tell it's on a Duo and stays off.

Until then, set Settings › Apps › Safari › Advanced › Advanced Tracking and Fingerprinting Protection to Private Browsing, and Brim will work in regular tabs. ### 5/5 — Works as it should *2026-11-08* Was skeptical to buy because of the one star review but actually works. Does what it says is will ### 1/5 — Doesn’t work *2026-11-08* Doesn’t work **Developer response:** Thanks for the report, and sorry Brim didn't work for you.

Enabled and disabled look exactly the same. And yes I have confirmed that all the settings are correct and that the extension is allowed on all sites. **Developer response:** Thanks for the report, and sorry Brim didn't work for you.

Brim expands web pages to utilize the full width of the iPhone Duo's outer display. It repositions links and buttons that would be obscured by side controls, ensuring a more complete browsing experience. ### How do I enable Brim's full-width browsing? To enable Brim, go to Settings > Apps > Safari > Extensions, turn on Brim, and set All Websites to Allow. Then, in Safari's page menu, select Brim and choose 'Wide'. ### Is Brim private and secure? Yes, Brim is designed to be private. It requires no account, collects no analytics, and makes no network requests. It adjusts layouts on your iPhone without reading or sending your browsing data. ### Does Brim work on all iPhones? Brim is specifically made for the iPhone Duo. On other iPhones, Safari already uses the full width of the display, so there is no functionality for Brim to change. ### Can I turn Brim on or off for specific websites? Yes, you can choose 'Wide' or 'Off' from Safari's page menu for Brim. This choice applies across sites and tabs, and you can revert any site to its default view with a single tap. ### What is the price of Brim? Brim is a paid application, available for a one-time purchase of $0.89. ### How often is Brim updated? Brim was last updated on November 3, 2026, with version 26.45.0. This indicates recent development and ongoing support for the application. ### What is the age rating for Brim? Brim has an age rating of 4+, making it suitable for a wide range of users. ## Version history (last 3 releases) ### 26.46.0 — 2026-11-12 Split View on the unfolded iPhone Duo: with two Safari windows side by side, both now run edge to edge, including the left one, whose controls sit on the left. Fixed: in Split View the left window no longer loses its right edge. Fixed: unfolding the iPhone with a widened page open now lays the page out again for the larger screen. Pages no longer jump sideways while you scroll. Headers that slide in on scroll keep their buttons in place, and sideways carousels are left alone. A gentle, once-per-version prompt to rate Sidefill, plus a Rate link in the app and the Safari popup. Fixed: Sidefill did nothing when Safari's Advanced Tracking and Fingerprinting Protection was set to All Browsing. Safari then hides the real screen size, so Sidefill could not find the side strip. Pages now widen in that case too. Smoother: fewer layout passes on busy pages, and Sidefill steps back on a page where Safari keeps its own width instead of leaving a blurred bar. Clearer setup: the Open Settings button now explains that Settings opens on Sidefill's own page and how to reach Safari › Extensions › Sidefill from there. ### 26.45.1 — 2026-11-08 Brim now speaks Japanese, Chinese (Simplified and Traditional), German, French, Spanish, Italian, Portuguese (Brazil) and Dutch. ### 26.45.0 — 2026-11-03 No release notes. ## More apps by Seokyong Kim - [Trappist](https://appshunter.io/ios/app/trappist/id6789916170) - [Rapport: Conversation Practice](https://appshunter.io/ios/app/rapport-conversation-practice/id6792348452) - [Cambler: Y2K CCD Camcorder](https://appshunter.io/ios/app/cambler-y2k-ccd-camcorder/id6802260520) - [Agent Cat Mobile](https://appshunter.io/ios/app/agent-cat-mobile/id6804198497) All apps by Seokyong Kim: https://appshunter.io/developer/1896658019 ## Related topics [brim](https://appshunter.io/ios/topics/brim) · [sierra interactive](https://appshunter.io/ios/topics/sierra-interactive) · [phishingoff for safari](https://appshunter.io/ios/topics/phishingoff-for-safari) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
