# Roblox vs Jelly Defender

The clearest difference is price: Roblox at Free against Jelly Defender's $0.99. Roblox also leads on rating (4.5 vs 3.0) and update cadence (every 6 days vs every 3 months). Jelly Defender's advantage is in-app purchases (none vs 16) and iOS requirement (11.0 vs 14.0). On ads and device support there is nothing between them.

Roblox is free to download; Jelly Defender costs $0.99 up front. Roblox sells 16 in-app purchases, starting at $4.99 per month. Jelly Defender asks for nothing beyond the download.

Roblox holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 3, so its average is the more settled of the two.

Roblox ships an update every 6 days, Jelly Defender every 3 months. Both last shipped on October 24, 2026.
