# Acrobots vs Voice Changer Plus

The clearest difference is price: Voice Changer Plus at Free against Acrobots's $0.99. Voice Changer Plus also leads on ratings volume (44K vs 24). Acrobots's advantage is in-app purchases (none vs 3) and ads (none vs shown). On rating, update cadence and device support there is nothing between them.

Voice Changer Plus is free to download; Acrobots costs $0.99 up front. Voice Changer Plus sells 3 one-off in-app purchases. Acrobots asks for nothing beyond the download.

Voice Changer Plus holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Voice Changer Plus has 44K ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 87% of Acrobots's written reviews are positive against 74% of Voice Changer Plus's, so the app with the better star average is not the one people write more warmly about.

Acrobots ships an update every 5 weeks, Voice Changer Plus every 6 weeks. The most recent releases landed on October 11, 2026 and October 15, 2026 respectively.
