SingSpark vs SingTrace

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.

SingTrace: Daily Singing Practice Build a real singing habit by recording yourself, listening back honestly, and noticing how you improve over time. SingTrace is a local-first practice journal for singers. Your recordings stay on your device. Label takes by song, compare versions from different days, and keep showing up -- one session at a time. Practice That Fits Your Life: Daily Recording Habit: Set a reminder, tap record, and capture a practice take in seconds: covers, originals, warmups, or free-form singing. Your Personal Archive: Every take is saved locally with dates and song labels. Revisit your history and hear how your voice changes week to week. Listen and Compare: Playback, scrubbing, and side-by-side listening help you notice tone, timing, and feel; not just what you think you sound like in the moment. Studio Analysis (Optional): Subscription to SingTrace Pro provides lightweight vocal metrics: pitch trace, range, dynamics, sustain, and phrase highlights; without turning practice into a scoreboard. Progress, Not Perfection: SingTrace is designed to encourage consistency, not grade you like a karaoke machine. Metrics support your ear; they don’t replace it. Track streaks and milestones as you build the habit of recording and listening back. How It Works: 1. Record a practice take (onboarding includes one free studio analysis for recordings over 10 seconds). 2. Listen back and review your archive by date or song. 3. Subscribe to run studio analysis on future takes when you want deeper feedback. Your voice improves when you practice, record, and listen. SingTrace makes that loop easy to repeat.
