Stop guessing. Start playing by ear
Use Trill as your daily pitch trainer for chords, chord progressions, intervals, notes, and melodies — and hear music 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.

Faster paced than I’d like but still hugely beneficial

Trill has given me a huge boost in confidence in my musical abilities and brought me so much more enjoyment to listening to and playing music. My progress wasn’t as fast as many of the creators promoting the app online. And after weeks using the app I’m still not to the point where I can recognize chords beyond major and minor. But practice recognizing pitches and intervals has really upped my ability to play melodies by ear and read musical notation more quickly. I wish its learning journey was slower and deeper. Some of the steps in the journey feel like huge jumps. I end up spending most of my time in the practice section of the app doing a variety of exercises closer to the level of ability I’m at. But that’s mostly a minor inconvenience rather than a major bug. Very much recommend the app.
Developer Response
This is wonderful to hear. I’m especially happy that pitch and interval practice is helping you play melodies by ear and read notation faster. Your point about the learning journey making some big jumps is fair, and it’s something I want to keep improving so it feels slower and deeper when needed. Many thanks, Jozef, founder of Trill!
Nice try

This app, presented as a game, fails in several respects. It doesn’t really TEACH anything. It’s just a series of repetitions of the same material over and over, with no attempt to help the user actually get better. Pitch recognition is a complex activity, very subjective to each person’s experience and imagination. The app does not address pitch recognition complexities, it just keeps throwing random pitches at the user, who is forced to merely guess and discover that they were wrong. The app doesn’t even seem to recognize which pitches are consistently missed, so there is no automatic repetition of problem areas that I could discern. And, once you get going, there are NO DISCUSSIONS, NO EVALUATIONS, NADA. It feels like I am blindfolded, throwing darts to hit a target, and all I ever hear is MISSED AGAIN! Finally, the electronic keyboard they used to play chords and scales was either really cheap (I.e. terrible) or in need of repair. There are notes in the lowest octave which sound like a hammer hitting a bell. The resulting overtones interfere with the accurate presentation of intervals and chords in particular. I should have waited before falling for the yearly subscription..I am stuck paying for an entire year, while still needing to find a good pitch training app. My advice: LOOK ELSEWHERE.
Fun!

Nice UI. The chord spellings and scales get a little funky sometimes but it’s alright, it’s kind of charming/engaging. Plus a lot of real world enharmonics pull the funny spellings anyways. Coming back to ear training after undergrad and graduate music degrees. This app is working out great for me. The audio gets weird when I have my AirPods in or if I swipe out to a different app during a lesson (my RoK gathering must continue ungapped) Will update my review when I hit that top rank. I’m a silver 💀Edit: I’ve reached expert! Cool app. Works better with AirPods now than when I first got it (hardly worked with AirPods at all). My ears have improved quite a bit, and my instrument practice is more enriching/fun/easier as a result. I’ve got my hopes in this dev. Ear training isn’t life or death to me, so why not support an underdog? The gamification is fun, I like working through the four stages each day. Please keep up the good work! I recommend this app a lot.

Thanks so much for the detailed review — and congrats on reaching Expert! 💪Really glad to hear the app is helping and that your practice feels more fun and effective. Also appreciate the note on enharmonics and audio — we’re continuously improving both.We’re currently working on adding chord progression recognition 🎧I actually built this app because it’s something I personally needed as a musician, so it means a lot to hear it’s useful for you too.If you have any suggestions or ideas for improvement, feel free to reach out via support/feedback in the app.Thanks again for the support and for recommending the app — it means a lot! 🚀
No free version, but many ?s

I don’t mind a paid app, but this is one of those apps that asks you a lot of questions, gets you excited and then you can’t do anything at all without a trial or paying. I was getting really excited to start and then it was a bit of a crash when I realized it was another “personalization” before a mandatory trial. I know apps need to make money, and this probably works to make people feel invested before you ask, but I feel like that approach wastes my time if I’m not in the position to pick up another subscription. I do think it’s a great idea for an app though!
Developer Response
I appreciate the honest take, and I’m sorry the setup made the trial feel like a surprise after you’d already invested time. Trill has a 7-day free trial with no commitment: cancel before it ends to avoid being charged. With notifications on, we remind you 2 days before it ends. After expiry, you can keep using Trill for free with limited features and a daily exercise allowance. Many thanks, Jozef, founder of Trill!
