# Zonium vs Plan

The clearest difference is in-app purchases: Plan at none against Zonium's 1. Plan also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 75%). Zonium's advantage is ratings volume (11 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Zonium sells 1 in-app purchase, starting at $5.99 per month. Plan asks for nothing beyond the download.

Plan holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Zonium has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of Zonium's written reviews are positive against 100% of Plan's.
