Sound
I can’t hear the notes
Tap Sound Check. It plays two notes so you can set your volume with the volume buttons. The app plays sound even when the Ring/Silent switch is set to silent, so the switch is not the cause. If you use Bluetooth headphones or a speaker, check that they are connected.
The app says “Audio paused”
A phone call, an alarm or another app took over the sound. Tap Sound Check or tap the fretboard and the sound comes back.
How do I hear a question again?
Tap the fretboard. You can replay the two notes as many times as you like while the clock is running.
Playing
How is a round scored?
A correct answer scores 25 points and moves you to the next question. Each wrong answer costs 10 points and the same question stays up until you get it. Rounds last from 30 seconds at Level 1 to 2 minutes at Level 8. The clock keeps running the whole time.
Why does bass have four levels and guitar eight?
Levels 1 to 4 use the E, A, D and G strings, which are the four strings of the bass and the four low strings of the guitar. Levels 5 to 8 repeat those levels across all six guitar strings, so they bring in the B and high E strings. A four-string bass has no more strings to add.
Does the app work offline?
Yes. Every level works without a connection, and your personal bests are saved on your phone.
Leaderboard and account
How do I get on the leaderboard?
Open Leaderboard / Account and sign in with Apple. You can pick a nickname or let the app generate one. After that, rounds you play while connected count toward the leaderboard.
My score isn’t on the leaderboard
- Only rounds that start while you are signed in and online count. The app tells you before the round when it is saving the score on your phone only.
- A round played offline is never uploaded later. It still counts toward your personal best on the phone.
- If the app asks you to verify your purchase, open Leaderboard / Account and choose Verify purchase. Apple may ask you to sign in to the App Store.
- The leaderboard shows your best score for each level. A lower score does not replace it.
How do I change my nickname?
Open Leaderboard / Account and choose Edit nickname.
How do I delete my account?
Open Leaderboard / Account and choose Delete account. This permanently deletes your game account, your nickname and your scores on the server, and it removes the app’s Sign in with Apple authorization. Personal bests saved on your phone stay until you delete the app. If the option doesn’t work for you, email the address above.
Purchases
How do I get a refund?
