The app can handle an arbitrary number of songs, that is lines of text (called lyrics) with chords (or fingerings) positioned at relevant places. Creating, editing or importing song is described later below. Please note that the app behaves differently if the song contains chords (thus independent from any tuning) or chord fingerings.

The song view screen

When you tap on a song, it is presented in “View Mode”. The “Edit” button at the top right allows to enter in editing mode and change the lyrics, the chords, transpose the whole song, etc.

The song can scroll and you can pinch to zoom in/out. The bottom toolbar gather some useful buttons/settings. If ever you feel that this toolbar is using too much screen space, you can always display the song in full screen by double tapping any empty area of the song.

Display menu

The first from the left shows the “Display” menu. You can there select how the song is displayed. If the song doesn’t have fingerings, you can automatically “Fingerize” it. Then Fingering, Chords and Lyrics can be individually switched on or off. There are some restriction however: you can’t switch everything off and you can’t show fingerings while hiding chords symbols.

When lyrics are hidden, the app can optionally reposition the chords in a more regular way (you can set this in the settings of the app). Otherwise, the app uses the lyrics to position the chords.

The last entry in the “Display” menu is the “Negative mode” switch. It allows to switch to a different color scheme (it can be used to define a “Night mode”). Colors for the regular and negative mode can be defined in the settings of the app. If the negative colors switch is engaged, the app will theme accordingly collections views so you’re not blinded by the change of colors if you jump back from a song to a collection. This setting persists between launches.

Please note that fonts can be set too in the settings of the app.

Audiotrack and auto scroll

The second button shows the “Track” menu where you can select an audio track to be played. You can also set autoscrolling properties of the song.

The audio track can come from your device’s music library (managed by iTunes). iTunes purchases must be effectively downloaded on the device to be reachable. You can also directly add mp3 or aac files. The app will copy them into its directory. To add audio tracks to the app, you can use the “Open in…” menu on such a file from another app. Alternatively, you can use iTunes on a computer and drop some audio tracks into the document directory of the app. shows tracks from your music library, and , those managed by the app. You can delete these files in the Settings of the app, Document section, Tracks tab.

Please note that in order to save space, audio tracks files are not synchronized by iCloud. When the app looks for a file it doesn’t find, it shows a “Track not available on this device” message. You simply have to put the same file on this device (or download it from the cloud if it’s an iTunes purchase). Otherwise, no audio can be played, but playback will scroll normally.

If a track is selected, it will override by its length the scroll duration of the song. A control allows to slow to down to 1/3 of the speed and up to 3 times the speed of playback without modifying the pitch. Another control allows to change the pitch of the song from ± 1 octave, semitone by semitone. You can furthermore fine tune pitches to the cents.

The last section allows to set the Autoscroll. If no track is selected, you just have to specify how long the song lasts. This duration is indeed device independent and can be synced over iCloud while adapting to phones or tablets. The effective scrolling speed is then computed from this duration. This speed is expressed in “lines of songs / second” and should correspond roughly to the time it take to play/sing a full line of the song. If a track is selected, the song duration is automatically set.

When you hit the play button, the song starts to scroll. What’s disappearing first is the first line, but this is most likely what you’re playing at the same moment. To solve this issue, you can set an optional start delay. The timer will run (the song still lasts the same time), but the song will begin to scroll only after this delay.

A symmetric issue occurs with the last line of the song which appears only until the last seconds, whereas you need to see it a little before in order to play/sing it. Here again, you can require the song to reach its end a few seconds sooner with another optional delay.

These two delays can also be managed automatically. If you check the “Automatic start and stop scroll bounds” option, the song will start to scroll when you (roughly) reach one third of the screen and will stop when you reach the last third. These automatic delays are dynamic and depend on display settings (like the screen size or the scale), but you don’t have to worry about this. You simply set the duration of the song, keep the “Automatic bounds” checked, and you should be good to go.
