Know your type. Tape it. Send it. Rolevo is the toolkit actors actually use between auditions — figure out how you read on camera, build the materials that get you seen, and put your best take in front of people who matter. DISCOVER YOUR TYPE Take the archetype quiz to find the roles you naturally read for, see working actors who share your lane, and get a casting blueprint built from your own profile — not generic advice. RECORD SELF-TAPES WITH A READER Record your scene partner's lines in your own voice, then perform against them. The reader listens for your cue words and comes in on its own, so your hands stay free and your eyes stay up. Or use the teleprompter to scroll your script over the camera for monologues. BUILD YOUR MATERIALS Import an existing resume by photographing it, or build one from scratch and export a clean PDF. Get honest AI feedback on your headshots — framing, lighting, casting impression — and a shot list tailored to your type. GET REAL FEEDBACK Send a take to friends or mentors with a link. They watch it and leave timestamped notes. No account needed on their end. SHARE YOUR WORK A public profile and shareable resume link, with full control over what's visible.

Verdict

The call

The clearest difference is in-app purchases: Rolevo at none against Delta's 3. Rolevo also leads on update cadence (every 9 days vs every 4 weeks) and rating (5.0 vs 4.8). Delta's advantage is ratings volume (28K vs 6) and chart position (#109 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.
