No reader? No problem. OffBook Studio is built by a working actor, for actors. Acting is about listening and responding, not just timing, and that's exactly what most rehearsal apps get wrong. OFFBOOK STUDIO FEATURES • Smart PDF Import & Editing Import casting sides, edit dialogue, change speakers, add missing lines, and clean up your scene before rehearsal. • Responsive Cueing OffBook Studio listens for your spoken cue and delivers the next Reader line when it's time. • Built-In Teleprompter Keep your lines visible while rehearsing or recording, with adjustable text and current/next line guidance. • Classic Mode Choose or record a Reader performance in advance for fast, consistent, repeatable rehearsal. • Interactive LIVE Mode The words stay fixed to the script while the Reader performance responds to how you play the scene. Each take can feel different. • Reader Voices Choose a ready-made Reader voice, or record the Reader lines yourself and transform the voice while keeping your timing and performance. • Self-Tape Recording Rehearse and record your audition in one focused workflow directly from your iPhone. • Reader Audio Mix Controls Adjust the Reader level after your take and save the finished self-tape with the balance you want. HOW IT WORKS 1. Import your sides 2. Choose your role 3. Choose Classic Mode or Interactive LIVE 4. Rehearse on cue 5. Record your self-tape OffBook Studio was built for actors who need to rehearse, run lines, and self-tape when another actor is not available. Rehearse. Record. Book.

Prompter Cam shows your script on the screen while the camera records you, so you can read and look straight at the lens at the same time. How it works - Paste or type your script - Set the scrolling speed that fits how you talk - Press record and read. The camera and the teleprompter run together While you record - 1080p or 4K, front or back camera - Portrait and landscape, both are full modes - Pause, rewind a few seconds and continue in the same file - Live filters on the full screen preview - Sound level meter so you notice a dead microphone before you finish After you stop - The video is saved straight to Photos - A recording cut short by a call or a restart can be recovered Privacy - Video and audio stay on this device. We do not upload your recordings - The script you type stays on this device Recording time - You start with 60 minutes of recording time - Unlimited time, 4K and no ads come with the subscription or the one time purchase - Time packs are there if you only need a bit more Terms of Use (EULA): https://cofounder.co.kr/promptercam/terms Privacy Policy: https://cofounder.co.kr/promptercam/privacy

Verdict
The clearest difference is ads: OffBook Studio at none against Prompter Cam's shown. Prompter Cam's advantage is iOS requirement (18.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
