Call for Line vs Rehearsal
The Rehearsal app set the standard for line learning on the iPhone. Here's where Call for Line takes a different approach – and where Rehearsal still shines.
The Rehearsal app has been around for a long time and a lot of working actors swear by it. Its model is simple and it works: record yourself reading every other character's lines, then play the recording back with your own lines hidden, leaving gaps where you're meant to speak. It puts you in the driver's seat for every voice on stage.
Call for Line takes a different bet. Instead of asking you to record every other part yourself, the app reads them aloud for you in voices that don't sound like yours – so the cue lands the way it would in the room. And instead of leaving you to judge how you did, it listens, transcribes, and shows you the words you got and the words you missed. When you do want real voices in the scene, Recorded Voices lets you capture a scene partner's lines once and rehearse with them any time.
| Feature | Call for Line | Rehearsal |
|---|---|---|
| Primary use case | Memorizing lines for stage and screen with a scene partner that listens | Memorizing lines by recording your own voice for the other parts |
| Who reads the other parts | The app, in six distinct voices – or a real person you've recorded | You, recorded ahead of time for each character |
| Setup time per scene | Upload script, pick character, start – under a minute | Record every other character's lines yourself before you can rehearse |
| Recording real voices | Optional – record line by line, batch-record in Studio mode, or upload a recording that aligns itself | Required – recording is the core workflow |
| Listens while you perform | Yes – speech recognition with word-level diff against the script | No – playback only, no scoring |
| Accuracy scoring | Word-by-word diff with goals from 50% to 100% in 5% steps, plus a Word Perfect editor for mic mishears | Not built in |
| Progress tracking | Mastery scores, Off Book badges, streaks, and trouble lines per scene | Not built in |
| Built-in repertoire | The Stacks: 31 classic plays from Shakespeare, Chekhov, Wilde, Ibsen, and more | No built-in library |
| Hint system | Call for Line – feeds you a configurable few words when you're stuck | On-screen text serves as the hint |

When Rehearsal is the right call
You like total control. You want to choose the pacing, the accents, the dramatic pauses for every other character – and you're willing to put the recording time in. You've been doing it this way for years and it works. Rehearsal is a refined tool with a deep, loyal user base for a reason.
When Call for Line is the right call
You don't want to spend the first hour recording before you can rehearse. You want a scene partner whose voice doesn't sound like yours so the cue actually feels like a cue. And you want hard data on whether you're really off book or just close to it – not a feeling, a number. Call for Line starts you rehearsing in under a minute, and when you do want real voices, Recorded Voices lets you capture your actual scene partner once and keep them forever.
The honest summary
Rehearsal's strength has always been that you control every voice. Call for Line now gives you both paths: instant rehearsal with built-in voices, or your real scene partner's recorded lines when it matters. Add word-level scoring and Off Book tracking, and it's the faster, more honest path to knowing your lines cold.
