I can play on the go to have better ideas of what I’m hearing on my phone for later correction in Pro Tools, or plug into one of my monitor sets at home to test my instinct... and it’s a game, with categories and scores. Much respect.” — justmikeaf “Trained me up well! This app helped me become MUCH faster with EQ, and helped me know with greater precision what I'm hearing all around .” — MarkBvllock ===== Quiztones Terms: https://theproaudiofiles.com/quiztones/terms/ Apple Standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Have you (or maybe one of your friends) ever wanted to learn to transcribe or play music by ear? It is so important for a musician to know what you are hearing. A good musical ear helps when you are composing, improvising, transcribing melodies, or playing with others. Most likely you have already tried different programs to learn to recognize intervals or even to acquire perfect pitch. However, although such programs develop your ear, but can you actually play any melody you hear as soon as you listen to it? Imagine you could understand music... It is like when somebody is talking to you, you not only hear pleasant sounds, but you recognize words and their meaning. One day I came across Alain Benbassat's program called "Functional Ear Trainer" and have been using it ever since. It is based on Alain's method to learn to recognize tones. The main difference between the Functional Ear Trainer and other methods is that it teaches you to distinguish between tones in the context of a particular musical key. You begin to recognize the role (or function) of each tone in this key, which is incredibly similar to its role in other keys of the same scale. And it is *guaranteed* anyone can gradually develop this skill. It does not matter: - who you are - an absolute beginner in music or a virtuoso professional musician; - how old you are - a 3 yo kid or a 90+ adult; - what musical instrument you play (you don't even have to play one). The only requirement is to practice for 10 minutes a day. I was so excited about this ear trainer that I have developed a mobile app based on the Alain Benbassat method. I hope you will find it useful.

Verdict
The clearest difference is review sentiment: Functional Ear Trainer at 96% against Quiztones's 64%. Functional Ear Trainer also leads on rating (4.9 vs 4.6) and ratings volume (3.8K vs 356). Quiztones's advantage is update cadence (every 3 months vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Quiztones sells 3 in-app purchases, starting at $4.99 per month and Functional Ear Trainer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Functional Ear Trainer holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Functional Ear Trainer has 3.8K ratings behind it against 356, so its average is the more settled of the two. Written reviews point the same way: 64% of Quiztones's written reviews are positive against 96% of Functional Ear Trainer's.
Quiztones ships an update every 3 months, Functional Ear Trainer every 7 months. Both last shipped on October 26, 2026.
