Intervals are a core part of music theory. By understanding the concepts and practicing consistently, anyone can build a solid foundation in music. This app is divided into four areas—Interval Theory, Interval Calculator, Interval Test, and Interval Ear Training—with each area offering focused, specialized learning. * Interval Theory The theory section explains interval numbers (2nd, 3rd, etc.), simple and compound intervals, harmonic and melodic intervals, inverted intervals, and interval calculation in a clear, structured way—so anyone can understand the underlying principles with ease. * Interval Calculator Once you understand the theory, try calculating intervals yourself. When you place two notes on a staff, the interval name is calculated and displayed instantly. The same notes are also shown on a piano keyboard, helping you understand intervals more intuitively. You can also set key signatures and clefs to calculate more complex intervals with ease. * Interval Test You can choose options such as key signatures, accidentals, staff types, and clefs to create the kinds of interval questions you want. Build your skills by solving problems like a game—the tougher the options and the higher your score, the more dazzling the fireworks, giving you a strong sense of achievement. * Interval Ear Training It's essential to recognize the unique "color" of each interval by ear. With practice, you can sharpen your listening skills. Choose relative or absolute pitch, melodic or harmonic intervals, difficulty level, and playback speed to create your own personalized ear-training sessions. * Interval Sight-Singing On the Interval Calculator screen, you can practice interval sight-singing by playing two notes one after another. The two notes are played about 2 seconds apart. After hearing the first note, imagine the pitch of the second note in your mind and sing it aloud. Then compare your own pitch with the note that actually plays to improve your ear and sense of pitch. The developer of this app has experience teaching students in a university music department. Drawing on that experience, the app was designed to help you understand music theory in a musical and practical way. We hope it will be a valuable resource for your musical journey. Formerly known as "Interval Test"

Verdict
The clearest difference is rating: Interval Calculator & Quiz at 4.4 against Interval Ear Training's 4.0. Interval Calculator & Quiz also leads on ratings volume (7 vs 1). Interval Ear Training's advantage is update cadence (every 3 days vs monthly) and review sentiment (100% vs 80%). 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. Interval Calculator & Quiz sells 1 one-off in-app purchase and Interval Ear Training sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Interval Calculator & Quiz holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Interval Calculator & Quiz has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of Interval Calculator & Quiz's written reviews are positive against 100% of Interval Ear Training's, so the app with the better star average is not the one people write more warmly about.
Interval Calculator & Quiz ships an update monthly, Interval Ear Training every 3 days. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
