Hi — I'm Steve. I'm a working actor, and I built Off Book! for myself because I was tired of scribbling on scripts and recording lines into voice memos I could never find again. Turns out a bunch of other actors wanted it too. So here it is, made by an actor, for actors. THE GIST Record your script line by line, then play it back to run your scenes anywhere — on the bus, at the gym, pacing your kitchen at 1am the night before opening. It's dead simple: • Make a Work (your play), add your Scenes, drop in your Characters, and Record your Lines. • Recorded a 30-line scene and one line's out of order? Don't you dare start over. Tap the "+" to slip a new line in, or just press-and-hold a line and drag it where it belongs. Voilà. • Scenes out of order too? Same deal — long-press and drag. Fixed. NOW REHEARSE Tap the Rehearse icon and you're in. Play the whole scene, or pick the character YOU'RE playing and flip on "Mute My Line" — the scene plays right up to your cue, then pauses just long enough for you to nail the line before your next cue rolls in. Want a little nudge? "Cue My Line" gives you a friendly *ding* right before it's your turn. And here's the good part for runaround rehearsing: playback keeps going when your screen locks or you switch apps. Lock-screen, Control Center, and headphone controls all work — so you can run lines completely hands-free. Speed it up, slow it down, loop a scene till it sticks. LINESYNC — RUN LINES WITH YOUR CAST Doing a show with other people? LineSync lets a director share a show's lines and recordings with the whole cast across phones. Invite your actors by email; they sync everything to their own phone for FREE. As castmates record their lines, the director hears them show up automatically — no nagging. LineSync is a small monthly subscription per show, paid by the director. The cast never pays a dime. BUILT FOR EVERY ACTOR Dynamic Type, VoiceOver, and Dark Mode work throughout — because the stage is for everybody. Off Book! is free with ads. If the ads cramp your style, there's a one-time "Remove Ads" tap and they're gone forever. Got a slick feature idea, or (gasp!) found a bug? Hit the support link and there's an email box waiting at the bottom — I read them myself. Now go get off book. Break a leg. — Steve ——— PRO TIPS ——— • "It won't save my lines!" → You probably skipped the microphone permission. Reinstall and tap YES when it asks, or go to iPhone Settings → Off Book! → switch Microphone ON. • To DELETE a Line, Character, Scene, or Work: swipe right-to-left and tap Delete. Careful — deleting a Character also deletes its Lines. • Long scene, phone left unattended? Set Auto-Lock to a long time (or Never) so it doesn't nap mid-rehearsal.
