Looks very pretty, and very convenient to look at multiple clocks! However, there is something seriously wrong with rendering of the globe. Moving it around is very jittery, and the app easily skyrockets to 100% CPU or more (multiple cores I guess). It seems like there is some intense computation (which itself can probably be optimized) being done on GUI thread. The app also crashed, then managed to crash the system UI somehow after restarting it.
Love the design, though, and will definitely replace the worldclocks app with this once it doesn't eat the CPU! This is on the Jolla Phone 2026.
