Store listing
By Marc Kerstein, from the App StoreDescription by Marc Kerstein Written by the developer, not by AppBrain. Click to read.
Here's what happens:
- You ask a friend to take out their phone, mute the volume and open YouTube.
- You then take your friend's phone and play a song, giving the phone back with its screen facing downwards.
- Now you apparently mentally transmit the thought-of song to your friend.
- Your friend names *any* song, turns the volume up on their phone and looks at the screen to hear and see that your prediction was correct... that exact song is playing on their phone!
The entire effect happens on their phone.
Earworm is built for real-world performance. It gives you multiple advanced input methods, flexible reveal options, and powerful integrations so you can adapt the routine to your style, language, and audience.
Everything can be inspected afterwards, with nothing suspicious to find.
Features include:
- Predict songs, music videos, trailers, or almost any searchable video
- Multiple input methods, including voice and covert browser input
- Performable in multiple languages
- No accomplice required
- No memory work
- Integrations with many third-party magic apps
- Notification support for additional confirmation
And with Earworm Pro:
- Supports Bluetooth peek devices, including the PeekSmith and Lumen Duo as part of Earworm Pro
- Never touch their phone with Earworm Remote
- Enhanced input methods
Earworm Pro is an optional purchase that brings even more advanced performance tools, including:
Enhanced Voice input
- Automatically detect songs mentioned in conversation.
- Uses your own funded AI account and API key for best-in-class recognition.
- Black mode offers a covert input with vibration cues.
Earworm Remote v2
- Perform Earworm without touching the spectator's phone.
- A new, even more natural way to share your video link.
- Auto Redirect and WikiTest integration for pairing and redirecting.
Send To Earworm
- Allow supported third-party apps to submit to Earworm, letting you reveal a freely chosen song via their input methods.
Peek Device Support
- New support for compatible peek devices.
- Live Peek support for the Notes input (to make it seem that you really did predict the chosen song!)
- Native PeekSmith and Lumen Duo support is built into Earworm Pro
Earworm is designed for performers who want a practical, modern, impossible-looking prediction effect.
