Not YYZ is a mind-bending app for knowledgeable fans of the band Rush. Not YYZ lets you hear what "YYZ" would sound like if Rush wasn't from Toronto. Neil Peart: "We were in a small plane and hearing from the cockpit the Morse code rhythm, and I said `Oh, wouldn't that be a neat introduction'...This song's an instrumental, but it's about YYZ airport. It's about airports." The beginning of "YYZ" by Rush is based on the Morse code for YYZ, which is the IATA airport identifier for Toronto Pearson International Airport. But what if Rush wasn't from Toronto? What would "YYZ" sound like if Rush was from your city? Not YYZ provides the answer. Pick any combination of three letters (other than YYZ) and Not YYZ will play it in the style of "YYZ" by Rush. If the letters match an airport identifier, the airport's name and location will appear in the player. Search for airports you've traveled through and cities you've visited. Try your initials. Create your own rhythms using the Morse code as a guide. The possibilities are endless!** FEATURES: -Browsable and searchable database of over 9000 airports. -Tap the Not YYZ banner or shake the device to get random letters in the letter picker. **Actually there are exactly 17575 playable possibilities.

Verdict
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.
