Stop guessing. Start hearing music.
Train your ear daily to recognize chords, intervals, and notes — and play by ear with confidence.
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.

Whenever the screen asking you to pay come up you can’t get out of it (took me a while to see you could even access the free features and had to fully close and reopen app to get out of the upgrade screen)
Musical grammar
AJIshey
Well, the features for listening are useful, the notes are not spelt correctly and only sharps are used. For example, F major has a Bb, not an A#. If the app is useful for training the year, but is confusing and incorrect theory.
not worth your time
Gerarrot
it was proving to actually be pretty useful at first, but then I realised it’s just another one of those apps that’s completely unusable unless you accept the free trial that you’ll inevitably forget to cancel. there is literally no way around it, trust me I’ve tried. not worth it.
Developer Response
We send a reminder notification 2 days before the trial ends to help avoid any unexpected charges.The free trial can be canceled anytime. The trial is required to provide full access to the structured training experience, rather than a limited demo, so it can be properly evaluated.
Exclusive Offer Not Working
DriftyPlays6647
If you close the app after being shown the £24.99 offer, it will prompt an ‘Exclusive Offer’ which will feature a 60% discount to £14.99. It seems attractive, right? But when you actually press Subscribe, it loads forever. Please fix this or I am not using your app.
