## What is MoyiWave?

MoyiWave turns your iPhone into a portable time signal transmitter. Sync your Casio Wave Ceptor, Citizen Atomic Timekeeping, or any radio-controlled watch in minutes -- even when you're traveling far from any broadcast tower.

--- HOW IT WORKS ---
Place your watch near the iPhone speaker, tap Start Sync, and let the encoded signal do its job. Most watches will detect the signal within 2-3 minutes.

--- SIX GLOBAL TIME STATIONS ---
- JJY 40 kHz / 60 kHz: Japan (NICT)
- WWVB 60 kHz: USA (NIST)
- DCF77 77.5 kHz: Germany (PTB)
- MSF 60 kHz: UK (NPL)
- BPC 68.5 kHz: China (NTSC)

--- MORE THAN A SIMPLE TRANSMITTER ---
Engineering Mode reveals the real-time bit stream, color-coded BIT GRID, and live time code decoding. Perfect for watch enthusiasts, ham radio operators, and anyone curious about how radio time codes really work.

--- FEATURES ---
- Real-time signal generation with industry-standard timing
- AM/PWM/PPM modulation matching each station's spec
- Automatic DST handling for DCF77 / MSF / WWVB
- Engineering Mode with BIT COLOR waveform and BIT GRID
- Live decoded fields: year, day-of-year, weekday, parity bits
- Pulse Indicator with realistic signal noise visualization
- Dual transmission channels (top earpiece + bottom speaker)
- 10-minute auto-stop to save battery
- Dark and light themes
- Works completely offline -- no account, no data collection

--- WHO IS IT FOR? ---
- Casio G-Shock, Oceanus, Edifice owners
- Citizen Eco-Drive Atomic owners
- Seiko Astron and other radio-controlled watches
- Hobbyists and engineers studying time code systems

--- PRIVACY ---
MoyiWave runs 100% offline. No analytics, no ads, no tracking, no account required.

--- NOTES ---
- Set your watch to manual reception mode (RCVD) for best results
- Maximize iPhone volume during transmission
- Place watch within 2 cm of the speaker
- Some watches (especially metal cases) may need multiple attempts
