••• Requires xScope 4 available from the Mac App Store ••• xScope Mirror lets designers and developers effortlessly preview any Mac desktop image directly on your iOS device or Apple Watch. Unlike other preview apps, xScope Mirror doesn’t have any desktop chrome to get in your way while you work or require you to save files again and again. Simply launch xScope Mirror on iOS and then xScope on a Mac to begin. Confirm the connection on iOS and then drop an image file onto the Dock icon for xScope. A remote connection to Photoshop is also supported: this lets you preview changes in your PSD while you edit. The Mirror can also display any window on your Mac or images copied to the clipboard. Finally, any image that's displayed on the iOS device can be transferred to the Apple Watch by tapping on its screen. Layouts that are taller than the watch's screen are scrollable. Any file that matches the icon sizes for the Apple Watch will be presented with circular mask against a black background, allowing quick asset previews. Features include: • Remote Viewing – Easily view the contents of any Mac desktop window on your iOS device or Apple Watch • Apple Watch – Includes a watch extension that makes previewing on your wrist a snap! • Pin & Lock – Move the Mac window anywhere (even under other windows) & it always stays in focus on iOS • Chromeless UI – No overlaid chrome to get in the way while you work • Retina Scaling - Preview mirrored content 3:1, 2:1, 1:1, 1:2 or 1:3, great for testing on Retina devices • Compatibility – Runs on all devices using iOS 5 or later • Security – Toggle user authentication requests on/off via Preferences in the xScope desktop app • Multi-client – Multiple iOS devices can connect and view the same Mac window – Great for demos or meetings • Sharing – Copy the current image to the iOS clipboard or save it in your Photos • Nudge – Nudge the selected window one pixel at a time (useful on Retina displays)

Know the best time to post on social media, anywhere in the world. When to Post instantly tells you whether now is a peak posting window for your audience, even if they're in a different timezone. A single colored dot gives you the answer at a glance. Green means a peak posting window is happening right now. Orange means it isn't, and the app tells you exactly what's next: "Ends in 18m", "Today 9PM", or "Tomorrow 3AM". -- SEVEN SOCIAL MEDIA PLATFORMS See the best posting times for: • Facebook • Instagram • LinkedIn • TikTok • X • YouTube • YouTube Shorts Each platform includes its own weekly schedule based on peak engagement times. Hide the platforms you don't use to keep the menu clean and focused. -- BUILT AROUND YOUR AUDIENCE, NOT YOUR CLOCK The best time to post depends on where your audience is, not where you are. Choose your audience's location once, and every posting window is automatically converted to your local time. Search by city, country, timezone, or GMT. Whether you're posting from Paris for New York, Sydney for London, or Tokyo for Los Angeles, the app does the timezone math for you. -- WIDGETS AND NOTIFICATIONS Keep the next posting window on your phone (directly on your lock and apps screens) with small and medium widgets. Prefer not to keep checking? Get notified the moment a peak window begins. -- RESEARCH-BASED RECOMMENDATIONS Posting windows are based on published engagement research across billions of social media posts. Studies identify the strongest hours and weekdays for each platform using the audience's local timezone. These are population averages, not guarantees. Every audience is different, so use the suggested windows as a starting point and refine them with your own analytics over time. -- PRIVATE BY DESIGN No account. No sign in. No tracking. Everything ships inside the app, works completely offline, and never sends your data anywhere.
