The goal goes in. The plot twist lands. Your friend says something so unexpected that everyone loses it. Then comes the familiar thought: “I wish I had recorded that.”
Fesi is built for those moments. Reaction Mode uses on-device detection to capture reactions, helping you stay involved in what you’re watching instead of waiting with your finger over a record button.
Your reaction happens once
A surprised face, an uncontrollable laugh, or the moment you jump out of your seat carries an energy that is difficult to recreate. Fesi helps capture that energy while you watch sports, movies, streams or games.
Set your phone somewhere stable, make sure you’re visible, and start Reaction Mode. Leave enough room in the frame if you tend to stand up or move around. Keep the app open while it captures your reactions.
Keep the buildup, too
Fesi uses a short rolling buffer to include footage from before a reaction is detected. That gives your clip context rather than starting only after you’ve already gasped or started laughing.
Detection varies with lighting, framing and background noise. Save Recent Moment gives you a manual way to preserve a moment while Reaction Mode is ready.
Spend less time looking for the good parts
Recording a whole watch session can leave you with a long video to search through later. Fesi’s reaction-focused workflow collects individual moments in your Library. Open a clip, watch it back, rename it and trim it before sharing.
A name like “Last-minute winner” is easier to recognize than a collection of unnamed recordings.
Keep your reactions on your device
Fesi processes reaction detection on your device and stores your recordings locally. You review the clips and decide what to share. See our privacy policy for details about the app and its services.
