A little closer, even from far away.
They sent
a video.
Send back you.
The laugh. The surprise. The “wait, what?” Record your reaction while you watch and send it to the friend who shared it.
No ReactDuo account. Reactions processed on your phone.

FROM A LINK OR AN APP
- TikTok
- YouTube & Shorts
- SoundCloud
LESS EXPLAINING. MORE REACTING.
A reply they can feel.
No need to describe how funny it was.
Let your friend see for themselves.
- 01
Open something good.
Share a supported video link to ReactDuo, paste it in the app, or choose a source in Record App.
- 02
Be yourself.
Start your reaction and approve the required Android prompts. Watch with the floating camera. Tap it to find Stop.
- 03
Send the moment back.
Tap Share, choose a messaging app and pick your friend. Watch it first or save a copy if you like.
YOUR REACTION. YOUR WAY.
From “I saw it”
to “look at me.”
Record your face and voice, or choose a combined layout with the original video when capture is permitted.
Keep the result in your library, trim the beginning, or send it straight to a friend.
Find your recording format ↗
PERSONAL MEANS PERSONAL.
Your phone.
Your moments.
ReactDuo processes recordings on your device. There is no ReactDuo cloud upload or public feed in this beta. You choose what to share, where to send it and when to delete it.
Read our privacy policy ↗Do I need to create an account?
No ReactDuo account is needed. Your source and messaging apps may require their own accounts.
Should I wear headphones?
We recommend them. Your microphone can pick up audio from a speaker. Separate playback audio depends on the source, Android and your audio output. Read the audio tips.
Can I just watch without recording?
Yes. Turn off Record reactions to open supported links in their source app without starting a reaction.
Can my friend watch without ReactDuo?
ReactDuo shares an MP4 through compatible apps. Your friend can watch it in an app that supports the video; they do not need ReactDuo.
NEXT STOP: YOUR ANDROID.
Good things are
better with a reaction.
We’re preparing the ReactDuo Android beta. Google Play access is not open yet. This page will link to the test when it’s ready.
