Songbook app

Songbook (app store link) is is a free app that will read Chord Pro files and display them on your iPhone. Getting the files into the application can be a bit tricky, but once you have figured that out it does a decent job of displaying them. However: Most not all guitarist sites on the internet offer versions in the Chord Pro format, which slightly limits Songbook’s usefulness.

Convert to PDF

You can also just convert any old webpage to a PDF and email that to yourself. It’s workable, but leaves you with fairly tiny, illegible versions of your songs… not ideal either.

Chordie.com

Chordie.com is a site that basically works as an aggreator, crawling chord and tab versions of songs on other sites. What makes Chordie special is that it automatically detects chords within files and can then also do clever things such as transposing songs for different vocal ranges or instruments. It displays chord charts for all the chords used in a song and also features an auto-scroll mode.

On your iPhone the site will be displayed in a great, touch-friendly format and a tap on a song will start and stop the auto-scroll feature. You can also create a free account on the site and strore your favorite songs in your personal Songbook, making it easy to access songs with just a few taps.

Conclusion

Personally I’ve found Chordie.com easily the best way to access chord and tab files from my iPhone. The main drawback is that it requires you to have an internet connection, so the other solutions might come in useful from time to time as well, but Chordie is highly recommended!
