Off Book! is an app designed by an actor for actors. I perform regularly and designed this app for myself to assist in script memorization.

New for version 4.0 - LineSync! will enable you to share your lines with other performers (available through in-app purchase)

It's really simple to use. You basically create your Works, Scenes, add Characters, and Record Lines! Should you accidentally record a 30+ line scene and realize that you have one of the lines out of order, you don't have to start over! Either hit the line "plus" signet insert a new line immediately after, or simply press on the offending line, and drag it to a new position! Voilà! You are all set.

If your scenes are out of order: same deal. Long press on the scene and move it to the position you like.

Once you are done recording the lines for the scene you wish to rehearse, tap on the rehearse icon and you are presented with the rehearse screen. From here you can choose to play through the entire scene, as well as mute/cue your line. To mute your line, simply select the character you will be playing by tapping the "down arrow", and then clicking the "Mute My Line" switch so that it shows green. The scene will play through and when it gets to your line, it will pause for the line length...giving you time to say it and wait for your next cue. The "Cue My Line" switch will cue the line for you by providing an audible "ding" immediately prior.

Please see the *INSTRUCTIONAL VIDEOS* in the app, or on my website, and if you have any neat feature requests or (gasp!) bug reports, please don't hesitate to contact me about them.

Please do NOT hesitate to contact me at the support web link listed here. There is an email box there at the bottom of the page for you to mail me should you experience any bugs you may need fixed!



*************** PRO TIPS ***************
FOR THE PEOPLE WHO SAY IT WON'T SAVE YOUR LINES: It is possible you did not accept the "Let Off Book! have access to your Microphone" permission. If this is a first time install, just uninstall the app, and reinstall. When the popup asks for permissions, approve them.

Alternatively you can go into the iPhone settings, scroll down until you find the Off Book! app, click it, and ensure that the microphone switch is turned ON.

To DELETE Lines, Characters, Scenes, or Works: Simply swipe your finger from right to left on the entry and a "Delete" button will pop up. Be careful with this, because if you delete a character in a work, you will also delete all of its Lines.

TO REORDER Lines: (in case you have one out of order and don't feel like deleting and recording all over again) hold your finger down on the line you want to move and then drag it into the proper position. You can see this demonstrated on the instructional videos I have included.

FOR LONG SCENES: Where you will leave the iPhone unattended, set your sleep timer/auto lock to either off, or maximum length so the phone doesn't go to sleep while you're rehearsing! (I am currently working to see if there is a way around this)

An essential tool for actors


I’ll get the bad stuff out of the way because there isn’t much. The interface is a bit of a mess. It’s not very appealing and usability is pretty poor. That’s it. Everything else about the app is great once you learn your way around. You have to record your lines and your cues which takes a bit of time but once that’s out of the way it’s well worth it. There are several configurable playback settings and you organize your sides in works (play, show, etc.) and scenes. This tool cuts my prep time in half and I don’t need to bug friends to read for me. I highly recommend this app.

Excellent for learning lines


Very easy to use - the training videos are exceptional. If you don’t want to record each character separately, you can always just record your lines and “others.”

Great app for learning lines


I've used this for two plays so far and plan to make it my go to line learner. The developer is very responsive and fixes any issues rapidly. Highly recommended!
