ReplayMac
A menu bar app for macOS 15+
The best clips happen while you're not recording.
ReplayMac keeps a rolling buffer of your screen and audio in memory. Whenever something happens that you want to keep, press a hotkey to save the last few minutes as an MP4.
In practice
Menu bar or Home control centre
Runs quietly in your menu bar or opens to the Home window. Check live buffer status, see your active display, and review clips saved during your session.
Always ready in memory
ReplayMac keeps your chosen window of recent screen time in memory, from 15 seconds up to 5 minutes, with extended replays up to 30 minutes saved to disk.
Instant MP4 export
Your clip saves directly to ~/Movies/ReplayMac/. Each recording opens in its own editor window with instant trimming, aspect cropping, and GIF export.
The Home window gives you live buffer status, quick capture controls, and every clip saved during your session.
I occasionally game on my Mac, and I miss the feature on my PS5 that lets me easily save clips from the past few minutes. ReplayMac essentially recreates this for me. Good work.

More ways to capture
Automatic game recording
ReplayMac can stay idle until a game starts, record for the duration of your gameplay, and stop as soon as the game quits. Built-in presets ignore game launchers like Steam, Epic Games, and Battle.net.
Continuous session recording
Start a full recording from the menu bar, Home window, or hotkey whenever you want standard start-to-finish capture. Files save with passthrough encoding, keeping exports fast and preserving original quality.
Multi-window editor and GIF export
Fine-tune clips with a dual-handle range selector, crop to 16:9, 1:1, 4:3, or 9:16 aspect ratios, and scale exports to 1080p or 720p with a live file size estimate and a Discord 100 MB indicator.
ReplayMac Companion
Turn your phone or tablet into a wireless desk remote for your Mac. Save replays, control recordings, and monitor your buffer with a single tap.
Deck mode controls
Keep your phone screen on next to your keyboard. Tap to save the rolling buffer or extended replay, start and stop sessions, and mute your microphone or system audio without switching apps.
Live buffer meters and clip roll
Watch your quick replay buffer and extended replay fill up in real time. Saved clips appear on your phone right away with thumbnails, duration, and file sizes, ready to reveal in Finder or send to the Trash.
Private local pairing
Your phone discovers your Mac automatically over local Wi-Fi, or connects over USB on Android. Pairing uses a 4-digit confirmation code and a local security key. Everything stays on your local network, and the server stays off until you enable it in ReplayMac.
Mute individual apps from the Audio Mixer, save replays and watch your buffer fill from Home, and switch displays or capture profiles from Capture Setup.
Free on the App Store for iPhone and iPad as ReplayCap Companion. Android users can install the .apk directly from GitHub releases.
