Learn to hear music. Not guess it. Have you ever wanted to play music by ear, recognize chords instantly, or identify the key of a melody? A trained musical ear changes everything. It helps you improvise, compose, transcribe melodies, sing in tune, and play with others confidently. Your musical ear is like a muscle. If you don’t train it, it stays weak. If you train it a little every day, it becomes instinct. Just 10 minutes of daily ear training is enough to build powerful musical hearing over time. Short, focused sessions train your brain to recognize tones, chords, and keys naturally — the same way athletes build strength with consistent workouts. And if you struggle with consistency, Trill makes you serious about it. With Focus Lock enabled, distracting apps are blocked until you complete your daily ear training. No scrolling first. No excuses. You train your ear — then you unlock your screen time. Train first. Scroll later. Funny part is, that Trill turns ear training into a game you actually want to come back to. Daily challenges, streaks, levels, and collectible badges transform serious ear training into a motivating system. Many users describe Trill as “Duolingo for ear training” — short sessions, clear progress, and constant small wins that keep you practicing. I originally built Trill for myself. I wanted to improvise more freely, hear the key of a song instantly, and recognize chords during jam sessions without guessing. What started as a personal tool became a complete daily training system for everyone who want real musical hearing. Free and Pro Features Free access includes an essential musician toolkit such as a tuner, metronome, and chord, interval, and scale visualizers. A free trial provides limited access to ear training and vocal training. Trill Pro unlocks unlimited training, advanced exercises, progress tracking, achievements, and Focus Lock.

Learn any song the way you actually practice it. StemScriber pulls a song apart into its separate instruments so you can hear exactly what you're trying to play — then slows it down so you can keep up. What it does: • Isolate any instrument — mute the vocals and band, solo just the guitar (or bass, drums, piano, vocals). Finally hear the part that was buried in the mix. • Slow it down — drop the tempo without the pitch turning to chipmunks. Sit with a fast riff at half speed until it's under your fingers. • See the chords — a chord chart is generated for the song so you can follow the changes while you play. • Tuner + fretboard — built-in, free, no sign-up. Made for the way musicians really learn — by ear, slowed down, one part at a time. Whether you're working up a cover, learning a solo, or figuring out a bass line, StemScriber gets you from hearing it to playing it faster. Use it with music you own or have the rights to. Chord detection is a strong starting point, not a perfect transcription — it gets you playing fast, and you can trust your ears for the rest.
