SingSpark

SingSpark is a private singing-practice app for people who simply want to sing better.

No ads. No account. No social ranking. No cloud upload. Pick how you want to sing, follow three simple steps, and watch your pitch in real time.

Two ways to sing:
・Karaoke: import your own song, remove the vocals, change the key and follow the original pitch line
・Sing with your music app: play songs in Spotify, YouTube or any app while SingSpark shows how in tune you are

Made for your voice:
・My Voice: a 45-second test maps your range, then SingSpark suggests keys, marks your comfort zone on the pitch line and checks whether a song suits you
・Mic & monitoring: choose the iPhone, wired, USB or Bluetooth headset mic, and hear yourself with low-latency monitoring
・A fast, smooth real-time pitch line
・Take review with spectrum, pitch, section scores and a strict vocal coach
・Vocal Drills for pitch, scales, intervals, timing and high notes
・Song Analysis for imported phrases, reference pitch, beat points and practice segments
・Section loop and headphone sync calibration
・Coach-style polish for tuning, reverb and loudness, then export and share

Free and Pro:
Every feature is free for the first 3 days. After that, the free version keeps both singing modes, the live pitch line, 5 saved recordings, section loop and sync calibration, plus 1 vocal drill, 1 song analysis and 1 coach review per day.

SingSpark Pro is a one-time purchase, not a subscription. Pro unlocks key and speed change, vocal removal, unlimited recordings, unlimited drills and analysis, coach-style polish, and export sharing.

Note: SingSpark does not read Spotify, Apple Music, or other streaming app audio buffers. It analyzes microphone input and can mix with other music playback.
