Floating Picture-in-Picture

Only for Mac

Mac

Keep any window visible as a floating live view while you work. A real-time Picture-in-Picture mirror that keeps playing — even when the source is hidden. Reska keeps any window visible — as a floating, always-on-top live view. Pick a window and Reska shows a real-time Picture-in-Picture mirror of it in a small floating panel you keep on top while you work in another app. Watch a video, a sports match, a dashboard, a build log, a reference doc, or a video call while you get things done somewhere else. Reska shows a LIVE MIRROR — a copy of the window. It does not move, resize, or change the original window in any way; only Reska's own floating panel sits on top. Your other apps are never touched. WHY RESKA • It keeps playing. The mirror updates continuously and a playing video never restarts — switching focus or starting the mirror won't interrupt playback. • It works even when the source is covered. Because Reska mirrors the window itself (not the visible part of your screen), the live view keeps updating even while the source window is hidden behind other windows. • It follows you across Spaces. The floating panel travels with you when you switch Spaces, so your view is always there. • Apple-silicon native, lightweight, and built only on public APIs — no code injection, nothing that breaks on macOS updates. FEATURES • Floating Picture-in-Picture mirror of any window • Up to 2 mirrors at once • Adjustable opacity, so the panel blends into your workspace • A custom global hotkey to put the frontmost window into Picture-in-Picture instantly • Pick a window by click, or from the menu-bar list • Aspect-locked resize; grab anywhere to move • Low-power 30fps mode to save battery • Launch at login • English and Japanese PRIVATE BY DESIGN Reska is completely offline. It has no network access at all — nothing is recorded, saved, or sent. Everything stays on your Mac. The only permission Reska asks for is Screen Recording (macOS's name for screen capture), and it's used solely to draw the live mirror. PRICING Free to download. Start an optional 14-day full trial in the app — every feature, no limits. The trial does not renew or charge you automatically. When it ends, you can no longer create mirror windows unless you make a one-time purchase to unlock Reska forever. It is NOT a subscription. Restore Purchase is supported. GOOD TO KNOW • Reska shows a live view to watch — you interact with the original window itself, not through the mirror. • DRM-protected video (Netflix, Apple TV+, and similar) appears black when mirrored — a macOS restriction Reska can't work around. Use it for YouTube, video calls, local video, dashboards, docs, and more. • Floating above another app's fullscreen is best-effort and depends on that app and on macOS. Reska is Mac App Store only.
