Record your scene partner's lines, then practice the back-and-forth on your own. ◆ Who it's for Actors, voice actors, comedians, presenters — anyone who has to learn lines and then perform in front of people. Professional or not. ◆ How it works 1. Record your scene partner's lines 2. On the practice screen, play them back and say your own lines out loud 3. Tap to play. The app moves to the next line for you ◆ What you can do Work without looking at the screen Tap and swipe are all you need, so you can move around and keep your eyes up. Every action comes back as a small vibration. Change the playback speed From 0.5x to 2.0x. Slow it down to check a passage, or speed it up for a quick run-through. Attach a PDF script Link a PDF to a work and read it while you record. The file stays on your device — Understudy only points to it, so nothing is uploaded anywhere. Add bookmarks and jump to a page in one tap. Bring in audio you already have Import music or any audio file you've prepared. Useful when you practice against a sound cue. Export your recordings and share them Export a scene as a ZIP. Move it to another device, or hand it to the person you're working with. You can also practice against a ZIP someone else recorded, with their voice as your scene partner. ◆ From the developer At home, on the way to rehearsal, or in the hour before a performance — I wanted something I could practice with anywhere. That's why I made this. I hope it helps you. ◆ About Understudy Pro Everything you need to practice stays free.

blablabla is the rehearsal partner that reads every line that isn't yours. When the lines are in, switch to selftape and shoot the take without leaving the app. Built by an actor, for actors. We handle the blablabla. You handle the performance. Three ways to work on a scene, selftape included, now listed in 39 App Store markets. == Built for the way actors actually work == - Drop in a PDF, paste text, snap a photo of your pages, or import Fountain or Final Draft - The app figures out who speaks, in what order, and reads every line that isn't yours - Three ways to work: Listen, Practice, Selftape - In Practice you choose how much of your own line stays on screen: Full line, Hint, First letters, Hidden. Move the dial mid-scene, as often as you like. - Voice library: 80+ voices auto-cast to your scene's characters, recast any of them - 39 languages, end to end. Listing and full in-app text, every menu and prompt. == Selftape without a reader in the room == - Teleprompter overlay in portrait, wider chrome in landscape - Countdown, framing grid, mic-check banner - Front camera mirror baked into the saved take (what you saw is what you sent) - Background-safe: take a call mid-rehearsal, the app finalizes the clip == Memorize lines, off-book in days == - Practice mode listens for your line and advances automatically - Cue your own line if you blank (no judgment) - Track your sessions: deviations, time on each scene, streak == Pricing == - Free: 2 voiced scenes to try, every feature unlocked - Pro: $6.99/month or $69.99/year for 30+ voiced scenes a month plus selftape - One-off voice packs: $1.49 for 3 scenes, $4.99 for 10 scenes (no subscription needed) == Why this exists == Built by Elias Munk, a working actor 14 years in. The guilt of asking a friend to run lines for the seventh time is what made this. Your scripts are encrypted on your device and never used for AI training.
