Turn your iPhone or iPad into a dual-display web renderer with full remote control capabilities.

Key Features • Display separate web pages on your device and an external screen • Switch between mirrored and independent display modes • Control remotely through WebHooks or the Remote Control Portal • Change URLs, refresh pages, and toggle auto-refresh • Enable web inspector and debug your web pages and dashboards • Adjust brightness, sound, and UI visibility • Send speech messages and capture screenshots remotely • Enable Kiosk Mode for locked-down interactive displays Use Cases • Digital Signage: Show menus, announcements, or live dashboards on external monitors and update them remotely. • IoT Dashboards: Display smart home or system metrics on a dedicated screen with auto-refresh intervals. • Interactive Kiosks: Use your iPad as a control surface and show related content on an external display, for hotels, events, or information desks. Privacy First Web Sync collects no personal information. The only data ever transmitted consists of screenshots of web displays, and only when you trigger the screenshot function from the Remote Control Portal. These images are used solely to display back to you. Local Control You can use Web Sync entirely on your device without any remote connection. Configure URLs, refresh pages, switch modes, and more, all locally from the app’s Settings.  Kiosk Mode and remote control require a one-time in-app purchase.

Verdict

The call

The clearest difference is review sentiment: HTML Viewer at 85% against Web Sync's 0%. HTML Viewer also leads on monetization model (free vs free with in-app purchases) and ratings volume (102 vs 1). Web Sync's advantage is rating (5.0 vs 4.5). On price, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Web Sync holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: HTML Viewer has 102 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Web Sync's written reviews are positive against 85% of HTML Viewer's, so the app with the better star average is not the one people write more warmly about.
