Develop a mobile app for rhythm coaching

Core concept — it's a metronome built specifically for dancers. Instead of just a click or beep, it speaks counts aloud ("1, 2, 3, 4") or calls out dance-specific cues ("Slow, Slow, Quick, Quick") timed to the beat. Think of it as a rhythm coach rather than a musician's tool. The main features planned: Metronome with voice counts — numerical ("1, 2, 3…") or ballroom-style ("Slow"/"Quick"), where a Slow = half note and Quick = quarter note Move builder — users can sequence counts together to define a named dance move (e.g. "Foxtrot Basic: Slow, Slow, Quick, Quick"), tag it by dance style (Salsa, Waltz, Tango, etc.), and save it for reuse Umbrella sequences — group moves together into a full routine (e.g. "Rumba Basic Sequence" = Basic Square + Underarm + Crossover) Training modules — Step, Rhythm, and Freestyle modules with progressive learning, including biomechanical reminders ("Shoulders down", "Butt tucked in") and footwork diagrams Audio file player — upload a music file, adjust its speed, loop sections, and layer in voice callouts over it Goal tracking — log classes attended, moves learned, social dances, performances, etc. User accounts — login, subscriptions (monthly or annual), demographic profile (dance style, level, lead/follow), and progress memory across sessions Multi-device — phone, tablet, laptop, and TV casting In short: it's a dance training app that wraps a smart metronome with voice coaching, move choreography tools, and progress tracking — aimed at dancers from beginner to pro level across Latin, Smooth, and other styles.
