Tap-Relay

TapRelay turns your room into a playground — a multi-device reaction & fitness game.

Place several iPhones around the room. They light up one by one, and you run and tap them as fast as you can, using your reflexes, speed, and focus. Great as a party workout with friends, or solo reaction training.

■ Two Modes
- Simple: run to the lit device and tap
- Color Call: say the displayed ink color out loud — a Stroop brain-teaser (uses the microphone)

■ Features
- Connect 2–8 iPhones (no internet — devices connect directly to each other)
- 4 difficulty levels, combos, ranks, best-record tracking
- A distance setting that adds time to reach devices placed farther apart
- Solo practice with reaction-time display (works on one device)
- 3 BGM tracks (Dance / Rock / City Pop)
- Japanese & English
