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.

My Sides
Read full descriptionHide full description
My Sides is a rehearsal partner for actors. Import your screenplay, choose your character, and run your lines with AI voices playing every other part. HOW IT WORKS Import a script in PDF, Final Draft (.fdx), Fountain, or Fade In format. My Sides reads the screenplay, identifies every character, and builds an interactive rehearsal session. Pick the role you're playing, and the app voices all your scene partners while you speak your lines into the mic. The app listens to your delivery, checks it against the script, and tells you how close you got. Retry the lines you stumble on, skip the ones you've nailed, and track your score as you go. WORKS OUT OF THE BOX Fountain, Final Draft and Fade In scripts open instantly on any device, with no AI and no account. Apple's built-in voices read your scene partners straight away. PDFs need AI to read the screenplay layout. On iPhone 15 Pro, iPhone 16 and later, or an M-series iPad, that runs on the device for free. On older devices, connect a free Claude or OpenAI account and PDFs work there too. OPTIONAL PREMIUM VOICES Connect your own ElevenLabs account for realistic, natural-sounding voices. Give each character a distinct voice - different ages, accents, tones. SMARTER SCRIPT READING For complex or unusually formatted scripts, connect a Claude (Anthropic) or OpenAI account. These AI services are better at parsing messy formatting. Both offer free credits to new accounts. On devices with Apple Intelligence, on-device AI handles most scripts without any cloud service. SCENE-BY-SCENE REHEARSAL Long scripts are automatically split into rehearsable scenes. Practise one scene at a time, or run the full script end to end. BUILT FOR ACTORS - Speak your lines into the mic and get instant accuracy feedback - Lines are masked until you peek, and every reveal is counted in your session stats - Colour-coded characters so you can scan for your cue - Strict mode (word-for-word) or Sense mode (meaning preserved, wording flexible) - Session stats: pass rate, average score, retries, peeks used, line-by-line breakdown - Track your improvement across rehearsal sessions PRIVACY FIRST Your scripts stay on your device by default. Choose On-Device in Settings and script text never leaves the phone. Add your own Claude, OpenAI or ElevenLabs key and only then is text sent to that service, for parsing or voices. Audio is processed in real-time and never recorded or stored. No analytics, no tracking, no ads. API keys are stored in the iOS Keychain and never shared with anyone except the services they belong to. FREE TO USE One script with unlimited rehearsals, completely free. Unlock unlimited scripts with a single one-time purchase - no subscriptions.
