FlowTone

FlowTone is the first tone-learning game built for your fingers.

Mandarin tones are the #1 obstacle for learners. FlowTone replaces flashcards with a short, addictive memory loop:

1. Listen. A native sentence plays, with each character colored by its tone.
2. Remember. The sentence fades — only the characters remain.
3. Reproduce. Swipe the right tone for each syllable. (Right = Tone 1, up-right = Tone 2, V-shape = Tone 3, down = Tone 4, tap = neutral).

Why it works:
• Embodied cognition — your hand draws the tone contour, your body remembers.
• Cross-modal coding — color + shape + sound + gesture, all reinforcing the same target.
• Spaced repetition under the hood — words you miss come back tomorrow.

What's inside:
• Includes full HSK 1 level sentences with native audio.
• Option to unlock HSK 2 to 7-9 and advanced drills.
• Daily Tone — one new puzzle every 24 h, worldwide.
• Adaptive Drill — focuses on your weakest tones.
• Tone Pairs & Minimal Pairs — fix the confusions that matter most.
• 4 color palettes (Intuitive, Pleco, Dummitt, Hanping).
• Optional gesture pad or button pad.
• No ads. No tracking. No account.

Built on the Embodied Cognition + Cross-Modal Perception research line. Tested with real learners.
