# Kiosk vs Bio

The clearest difference is price: Bio at Free against Kiosk's $2.99. Bio also leads on rating (5.0 vs 4.0) and update cadence (every 2 weeks vs every 2 months). Kiosk's advantage is in-app purchases (none vs 3) and ratings volume (28 vs 2). On ads, device support and iOS requirement there is nothing between them.

Bio is free to download; Kiosk costs $2.99 up front. Bio sells 3 in-app purchases, starting at $2.99 per month. Kiosk asks for nothing beyond the download.

Bio holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Kiosk has 28 ratings behind it against 2, so its average is the more settled of the two.

Kiosk ships an update every 2 months, Bio every 2 weeks. The most recent releases landed on September 20, 2026 and September 11, 2026 respectively.
