Hear it, then play, sing or clap it back.
KeenEar trains your musical ear and sense of rhythm in short daily lessons. You hear a prompt and answer by tapping, clapping, singing, playing an instrument through an iRig, or on MIDI keys, and the app tells you right away what went well. Everything runs on your device. There is no account and nothing is uploaded to us. The first 10 lessons are free; KeenEar Pro unlocks all 56.
To hear your clapping, singing or instrument and score the answer. The sound is analysed on the device and not stored. If you refused it, turn it on in the iOS Settings app → KeenEar → Microphone. An exercise that needs the microphone also offers a button that opens these settings. Tapping and the on-screen keyboard work without it.
Bluetooth headphones delay the sound. For rhythm, wired headphones or the phone’s speaker are the most accurate. If you use Bluetooth, open Settings → Sound check and tap Calibrate: you tap along with a few clicks and the app measures the delay of that headphone.
Tap “I sang it correctly” or “I played it correctly” under the score. That tells the app, and us, that you disagree, and the exercise counts as passed. We use these answers to make the scoring fairer.
Yes. Connect a MIDI keyboard by USB (or pair one over Bluetooth) and melodies are played on its keys. A guitar or bass can be plugged in through an iRig or another USB audio interface. Choose how you answer in Settings → How you answer: voice, keys, guitar, bass or no instrument.
Settings → Note names offers C D E F G A H (Czech and German), C D E F G A B (English) and do re mi fa sol la ti. In solmization “do” is the tonic of the exercise, so a melody keeps its names in any key.
Settings → Find my level runs a short test of rhythm and notes, about four minutes. Lessons you already know are marked as done and you continue at your level: Beginner, Intermediate or Advanced. Nothing you have done is undone.
Your progress is stored only on the device. To delete it, delete the app. Settings → Show the introduction again lets you pick how you answer and the note names again without losing progress.
The first 10 lessons are free, together with the placement test, the reviews and your streak. KeenEar Pro unlocks all 56 lessons, from beginner to advanced: triplets, odd meters and fast syncopation; minor, modes and melodies in other keys; sevenths, the tritone and chromatic singing. Pro is a monthly subscription, or a yearly one with a 7-day free trial. Manage or cancel it in Settings → KeenEar Pro → Manage Subscription, or in your App Store account. If you cancel, your progress stays.
Open Settings → KeenEar Pro (or the KeenEar Pro screen) and tap Restore Purchases. The subscription is tied to your App Store account.
Everything above applies to the Android app too, with these differences:
The app collects no data. Read the full privacy policy.
KeenEar uses Apple's standard Terms of Use (EULA). KeenEar Pro is an optional auto-renewable subscription: monthly, or yearly with a 7-day free trial. The App Store shows the price in your local currency. Payment is charged to your Apple Account. The subscription renews unless you cancel at least 24 hours before the end of the current period.
