Same scene. A different you. Take Two is your personal voice acting practice space for iPhone and iPad. Choose from 24 original fictional scenes, or bring your own script. Record a performance, listen back, try a new intention, and hear what changed. • Your own scripts: paste text or import TXT, Markdown, RTF, and PDFs with selectable text. Review and edit your transcript before saving. • Optional teleprompter: preview a comfortable pace, then pause or rewind the scrolling script independently from recording. • Director’s Switch: follow a cue and change intention mid-scene. • A/B comparison: listen to two takes of the same scene. • Blind Take Test: compare randomized readings before revealing which is which. • Moment Pins: mark moments to keep or explore with timestamped annotations. • Local take library: save recordings, private notes, and favorites. • Optional audio export: share a copy of a single recording when you choose. The interface and all built-in scripts are available in English, Spanish, French, German, Brazilian Portuguese, Japanese, Simplified Chinese, Arabic, and Hebrew. Your own scripts stay in the language you provide. Practice offline with no account, automatic uploads, or ads. Imported scripts, recordings, and notes stay on your device unless you choose to share audio. Files may be included in device backups. Take Two does not transcribe recordings, generate voices, or score your performance. Recordings last up to 90 seconds. File imports support up to 2 MB; scanned PDFs require copying and pasting text from another app. Microphone permission is required only to record. Requires iOS or iPadOS 26 or later. Take Two supports your own practice and judgment; it does not promise professional results.

Verdict
The clearest difference is in-app purchases: Voice Acting Practice at none against 3D Solar System's 12. Voice Acting Practice also leads on ads (none vs shown). 3D Solar System's advantage is iOS requirement (16.0 vs 26.0). On price and device support there is nothing between them.
