Script Rehearser vs LineLearner: Which Line App Fits You?

Script Rehearser and LineLearner both help you learn lines by playing the other parts out loud, but they get those parts in opposite ways. Script Rehearser turns your script into audio with computer voices. LineLearner has you record every line yourself, your partners’ lines included.

That one difference decides most of what follows: how long setup takes, how natural the scene sounds, and what you pay. We compared the two apps on the same six points, with prices and platforms checked in October 2026. Our pick for most actors is Offbook, which reads every other role and listens for you; we explain why after the comparison.

How We Compared Them

Every line app has to answer the same six questions. They are the ones that decide whether you are still using it the night before your off-book date.

• Who reads the other parts? Your own recordings, computer voices, or AI voices.
• How does it know it is your turn? A fixed gap, a tap, or listening for you to finish.
• How does your script get in? Typing, importing a PDF, or photographing the pages.
• What memorization tools does it have? Hiding your lines, first-letter cues, repetition.
• Where does it run? iPhone, Android, Mac, or a browser.
• What does it cost? One-time price, subscription, and what is free.

Script Rehearser vs LineLearner at a Glance

Who Reads the Other Parts

This is the biggest difference, and the one to decide first.

Script Rehearser: computer voices, or yours

Script Rehearser reads the other characters with the voices built into your device, and in 2026 Engram added its own text-to-speech voices for English scripts. You can start rehearsing as soon as the script is in. With Pro you can also record your own voice and choose a voice for each character, so a two-hander does not sound like one person talking to themselves.

Computer voices are fast, but they read every line in the same flat way. For learning the words that rarely matters. For learning to listen and react, it can.

LineLearner: every line in your own voice

LineLearner has no text-to-speech at all. The developer left computer voices out on purpose, and the app is built around recordings: you record every line, including the other characters, and you can shift the pitch per character so the voices sound different. Recording a long scene takes time, but the result sounds like a reading, with the pauses and emphasis you chose.

LineLearner also lets you share a recorded script file with castmates, who add their own lines and send it back. For a cast that wants to rehearse with each other’s real voices between calls, that is a useful trick.

How Each App Knows It Is Your Turn

A line app is only as good as its timing. If it races past your line, you rush; if it waits too long, the scene loses its rhythm.

Script Rehearser offers four ways to run a scene: Listen Along, Wait For Me, Repeat for Confirmation, and Run Through. Wait For Me pauses at each of your lines until you are ready to go on, and Run Through leaves a fixed gap for each of your lines. None of the modes listens to you speak, so the app never knows whether you got the line right.

LineLearner works by leaving your part out. Turn your lines off and the recording plays the other characters with gaps where you speak. Because you recorded every cue yourself, the scene keeps the pace you gave it, so record the cues at the tempo you want to perform.

Getting Your Script In

Script Rehearser imports a PDF that contains real text, a .txt file, or lines you type. A scanned PDF (a picture of a page) will not import, so ask for sides as a text PDF when you can.

LineLearner can open a PDF or Word file, but only as a reference while you record. It does not turn the document into lines; the lines are your recordings. Plan for setup time that scales with the length of the scene.

Memorization Tools

Script Rehearser can show or hide your lines, or show only the first letter of each word. First-letter cues are one of the most effective ways to test recall without giving the line away: you see the shape of the sentence, and you have to supply the words. You can try the method on any text with our free first-letter memorizer.

LineLearner’s tool is the gap itself: hearing the cue and filling the silence out loud is active recall, which beats reading a line over and over. Repeat a scene until the gaps feel easy, then run it with the script closed.

Price and Platforms

LineLearner costs $3.99 once on the US App Store, with no in-app purchases, and a free lite version holds up to 10 lines. It runs on iPhone, iPad, and Apple silicon Macs, and there is a paid Android version.

Script Rehearser is a free download. Pro is $7.99 a year or $29.99 for unlimited access on the US App Store, and every new user gets a 30-day Pro trial that does not turn into a paid plan on its own. It runs on iPhone, iPad, Apple silicon Mac, Vision Pro, and Android. Schools can get free Pro access through offer codes.

Which One Suits You

• You want a reader that hears you finish your line: Offbook, which plays the next cue when you finish, with nothing to record.
• You are learning a full-length play: Offbook, where the page picker splits up to 150 pages into scenes.
• You want to start rehearsing in five minutes: Script Rehearser, because voices read the script as soon as it is in.
• You want the scene to sound human: LineLearner, if you have time to record every line, or a castmate to share the file with.
• You are on Android: both work; Script Rehearser is free to start.
• You learn best from first-letter cues: Script Rehearser has them built in.
• You want to pay once and never again: LineLearner at $3.99.

Why Offbook Is the Stronger Choice

Both apps share one limit: neither one hears you. Script Rehearser waits until you are ready or leaves a fixed gap, and LineLearner plays a recording with gaps in it. If you go up on a line or take a pause for a beat, the app does not know.

Offbook fills that gap. You upload the script (PDF, photos of the pages, or text), pick your role, and realistic voices read every other character. Offbook listens through your microphone and plays the next cue when you finish your line, with Strict, Lenient, or Manual matching so it fits how word-perfect you need to be. It also hides your lines, shows first-letter cues, and has a teleprompter mode that highlights each word as you say it.

It handles long scripts too. One scene holds up to 50 pages, and the page picker splits up to 150 pages into scenes, so a full-length play fits. You rehearse on your laptop with the full script on a big screen, and listen to your scenes on your phone anywhere.

Frequently Asked Questions

Is Script Rehearser free?

The download is free, and every new user gets a 30-day Pro trial that does not convert to a paid plan. After that, Pro is $7.99 a year or $29.99 for unlimited access on the US App Store (October 2026).

Does LineLearner read the lines for you?

No. LineLearner plays back recordings, so you or a castmate record every line. It has no text-to-speech and no speech recognition.

Can I use either app for a self-tape?

Script Rehearser can play the other parts while you record on your own camera or phone; the app itself does not record video. LineLearner can play your recorded cues while you film in the same way. For a full setup, see how to self-tape alone.

Which is better for a full-length play?

Offbook. The page picker splits up to 150 pages into scenes, and one scene holds up to 50 pages, so a full-length play fits with nothing to record. Between the two apps compared here, importing a text PDF into Script Rehearser is faster than recording a whole play in LineLearner. For a long role, also plan your schedule: our play library shows how many lines each role in the most-performed classics has, so you can work out lines per day. For any other script, paste it into our free script line counter.

The Verdict

Our pick for most actors is Offbook. It gives you what each of these apps does best in one place: voices for every other role with nothing to record, and a reader that actually listens and comes in when you finish your line. A full-length play fits, since the page picker splits up to 150 pages into scenes. That is the closest thing to a real scene partner, and it is ready any time you are.

Between the two apps compared here, the choice comes down to setup. Script Rehearser reads your cues as soon as a text PDF is in, and LineLearner plays back lines you record yourself, for a one-time $3.99. For more on how line apps compare, see our guide to the best line learning apps.
