Sing Sharp is your personal vocal coach — singing lessons, vocal training and a complete voice studio in one singing app. Learn to sing with real-time feedback, take the vocal range test, build perfect pitch with ear training, and unlock the voice you have always wanted. From singing lessons for beginners to advanced technique for experienced singers, every exercise adapts to your voice, your range and your goals. REAL-TIME FEEDBACK ON EVERY NOTE Sing Sharp listens while you sing, powered by advanced AI audio analysis. The built-in pitch detector analyzes your voice in real time, shows every note you hit or miss, and doubles as a precise voice tuner — check your pitch any time, on any note. Ever wonder whether you are singing in chest voice or head voice? Watch your vocal resonance visualized inside your body as you sing. PERSONALIZED SINGING LESSONS These are voice lessons that listen. No static, pre-recorded drills: Sing Sharp generates music dynamically — like a singing teacher playing the piano just for you — and keeps every vocal exercise inside your safe range, so you improve without straining your voice. VOCAL RANGE TEST Start with a quick voice test to find your true vocal range in minutes. See your lowest and highest notes, and watch your range grow as your vocal training progresses. VOCAL WARM UP & DAILY VOCAL EXERCISES Six focused programs full of vocal exercises for singers at every level: • Daily Workout — build a strong vocal foundation with daily singing exercises • Recovery Warmup — protect vocal health with gentle vocal fry exercises that improve vocal cord closure, release tension and prevent strain • Sing High Notes — build on vocal fry and relaxation technique to expand your vocal range and explore every quality of your high notes, from light falsetto to powerful belting, without voice cracks • Mix Mastery — blend chest voice and head voice into one smooth mixed voice • Vibrato Pro — coordinate vocal cords and diaphragm to unlock a natural, beautiful vibrato • Harmony & Trio — learn to sing vocal harmony, from simple thirds to multi-part arrangements, and train solfege through major and minor scales PERFECT PITCH & EAR TRAINING Think you are tone deaf? Almost nobody is — most voices are just untrained. Start with a simple tone deaf test, then build your musical ear and a real sense of solfege with daily pitch training and ear training exercises: recognize notes, match pitch and sing in tune, every time. From your first do re mi to a working feel for music theory, your ear grows as your voice does. INTERACTIVE LESSONS WITH VIDEO DEMONSTRATIONS Learn how to sing better, step by step, with video lessons from professional vocal coaches, built on a proven vocal coaching method — vocal warm ups, breathing exercises for singing, breath support and the technique behind falsetto, high notes and more. RECORD YOUR PROGRESS & TAKE ON CHALLENGES Record audio and video of your performance for a complete assessment, unlock achievements, and share your best takes with friends or the global vocalist community. Detailed progress tracking keeps your singing practice consistent and shows your voice training pay off, day by day. You know that one song — the one you sing with everything you've got when nobody else is around, the one that makes you feel, just for a moment, like a true singer. Now imagine singing it in front of people: not perfectly, but beautifully, confidently, proud of your own voice. That moment is not about talent. It is about training. Preparing for an audition, choir practice or karaoke night? Ready to become a singer at last?
