  • Great app! ★★★★★
    I found this app extremely user friendly and simple to use with a short turnaround. I work with the youth group at my church and think it's useful for our weekly worship. Thanks!

  • Crazy easy and convenient ★★★★★
    Seriously took less than 30 seconds to transpose an entire song. Punch in the chords, select the new key, and BAM. Donezo. 👍🏻👏🏻👏🏻👏🏻

  • Very satisfied so far ★★★★★
    Great for playing in bands. I play keys and sing. I often change the key to a song I want to cover to fit my vocal range and usually do so by ear. Transposing written chords here and then sending transposed song to bandmates seriously reduces chances for human error and speeds things up. Thank you!

  • Almost perfect for my needs ★★★★
    The transpositions are accurate and helpful. I find it difficult selecting the new key on my iPhone 6. It usually takes a few tries. But it gets me there.

  • Excellent ★★★★★
    If you're the sort of guitarist who would rather learn new chords, rather than use a capo, you'll find this app very useful. It is simple to use, and fairly intuitive, though some pop-up explanation of the various functions would be helpful. Good luck to the developers. I look forward to new versions, and would be happy to pay, say $1.99, for this app. It certainly beats using a transposing wheel.

    I like the quick transposition I wish it had a capo reference for guitars and I don't like the chord variants select but the fact that there is a chord transposer is fantastic yeah.
