Store description excerpt
SongSync AI is the private vocal coach for people who want to practice singing — quietly, at home, without uploading anything to a social feed and without touching anyone else's copyrighted music. WHY SONGSYNC • 5-dimension DNA score on every take: pitch (YIN cents), rhythm (Whisper-aligned timing), vibrato (long-tail stability), breath (RMS pause analysis), expression (AI). Result in ≈ 60 seconds. • Composition Rehearsal Loop (industry first): take 1 → DNA score → tap any weak axis → AI shows the exact weak seconds → you re-record → Δ chart shows your gain. Repeat until you hit your target. • Real-time pitch meter while you sing: ±50 cents at 30 fps, with a red warning the moment you drift more than 20 cents. • Weak-spot loop: practice a single phrase on repeat with the reference pitch line drawn under your voice. • DNA history: 7-day, 30-day, 365-day curves on every axis so you can prove to yourself that you actually got better. THE LIBRARY (CLEAN BY DESIGN) • 50 public-domain songs at launch: Twinkle, Greensleeves, Amazing Grace, Frère Jacques, Vivaldi & Caccini arias, Happy Birthday (EU PD 1893 melody), folk and national anthems, plus CC0 backing tracks from musopen.org and freemusicarchive.org. • Upload your own backing tracks (mp3 / m4a, ≤ 50 MB). Strictly private. Strictly your own. • No commercial / streaming songs are ever bundled — not even a 30-second demo. No social feed. No public profile. No leaderboards. PRIVACY BY DESIGN • Microphone permission is requested ONLY when you tap Record, and only while you record (the OS-level orange mic dot is your proof). • Audio recordings stay on your device. Whisper transcription happens over TLS to our self-hosted gateway and the audio bytes are dropped after the call. • No tracking, no ad networks, no IDFA prompt. • Account delete is one tap and cascades within 30 days (GDPR Edge Function), including device-local audio files. PRICING • Free tier: 3 practices / day, 14-day DNA history, full real-time pitch meter, weak-spot loop limited to 5 / day. • Pro: $4.99 / month or $19.99 / year (save 67%), with a 7-day free trial. Pro unlocks unlimited practice, full-year DNA history, unlimited weak-spot loops, and the complete Composition Rehearsal Loop. Built by a single indie developer chasing 20+ honest MVPs in 2026. No VC, no growth hacks, no harvested data — just careful design for people who care about their voice. Subscriptions auto-renew until canceled. Manage and cancel in App Store account settings. Pricing varies by region. LEGAL SongSync includes only public-domain works, CC0 / openly licensed backing tracks, your own voice recordings, and audio you upload that you have the right to use. We do not provide copyrighted music. You are responsible for the rights of anything you upload.
