Turn any video into a
reaction video
Drop a face‑cam bubble over a video and record your genuine reaction — laughs, gasps, commentary, all in one take. No green screen, no second app, no computer required.
iOS · Free · Everything happens on your device
Everything you need to react, right in the app
Position your bubble, pick your shot, and hit record — the built‑in editor takes care of the rest.
3 bubble shapes
Circle, rounded square, or 9:16 portrait — pick the frame that fits your video.
Front or rear camera
Flip anytime — mid‑recording — between your selfie cam and the world‑facing one.
Drag, zoom, frame
Reposition your bubble with a drag, pinch to zoom in or out, and frame the perfect shot.
Countdown timer
Off, 3 seconds, or 5 seconds — get in position before recording starts.
Independent audio mix
Two separate sliders for the original video and your mic — dial in the perfect balance.
Trim, save & share
Cut the start and end, save straight to Photos, or share to any app via the system sheet.
From video to reaction in three steps
Pick a video
Paste a direct video link (MP4, M3U8) or choose a clip from your library.
Frame your shot
Position your face‑cam bubble, choose a shape, flip cameras, and set a countdown.
Record, edit, share
ReacMoji captures the video, your camera, and your mic — trim, mix, then save or share.
Private by design
Everything happens on your device. Your camera, microphone, and recordings stay on your phone — ReacMoji has no server to send them to. Read the full Privacy Policy.
