# JamBase vs Not YYZ

The clearest difference is price: JamBase at Free against Not YYZ's $0.99. JamBase also leads on update cadence (fortnightly vs every 3 months) and ratings volume (1.7K vs 3). Not YYZ's advantage is review sentiment (90% vs 55%). On rating, ads, in-app purchases and device support there is nothing between them.

JamBase is free to download; Not YYZ costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

JamBase holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: JamBase has 1.7K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 55% of JamBase's written reviews are positive against 90% of Not YYZ's, so the app with the better star average is not the one people write more warmly about.

JamBase ships an update fortnightly, Not YYZ every 3 months. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
