jAMSKOOL Sing Trainer vs SingSpark

Pitch is a muscle. Work it. Sing Trainer is a daily pitch-training gym for your voice. Sustained tones, interval drills, sung scales. Real-time visual feedback on every note so you learn exactly where your voice sits, and where it needs to go. Built for singers, instrumentalists, and anyone who wants a more reliable voice. REAL-TIME PITCH FEEDBACK Sing into the mic and see your pitch plotted against the target in real time. Every cent of deviation visible instantly. No more guessing whether you're sharp or flat. The app shows you what you actually sound like, not what you think you sound like. THREE EXERCISES Random Notes: anything goes within the key. Sharpens your "find any pitch, fast" reflex. Dial in speed, jump style, chromatic intensity. Scales: stepwise, up and down. The bread and butter of pitch accuracy. Major, minor, and more, in any key. Arpeggios: triadic leaps. Root, third, fifth. Train the shapes of harmony and build the intervals you actually use. VOICE RANGE CALIBRATION Pick a voice type or sing your exact range. Drills stay inside your voice, not outside it. The app picks notes that sit comfortably for you, so practice builds confidence instead of frustration. THREE DIFFICULTY LEVELS Easy, Medium, Hard, across every exercise. Progress gradually or jump straight into the deep end. LANDSCAPE GAMEPLAY Turn the phone sideways. See every note. Scale degrees labelled, root notes flagged, your pitch drawn live across the staff as you sing. PROGRESS TRACKING Every session saved. Watch your sessions, perfect rounds, and streak build up over time. Filter by exercise and difficulty to see exactly where your voice is improving. ON-DEVICE PROCESSING Your microphone audio never leaves your phone. Pitch detection runs locally. No servers, no uploads, no recording. Just the app and your voice. WHAT SING TRAINER COLLECTS Nothing. No accounts. No email. No tracking. No ads. Microphone audio is processed on-device and never transmitted. Progress is stored locally only. PAY ONCE. KEEP FOREVER. $9.99 USD, one-time. No subscription. No levels to unlock. No in-app purchases. All three exercises, all difficulty levels, voice range calibration, landscape mode, progress tracking, included. Future updates included.
