Some other minor feedback:

Temperature range - can we change this between C and F?
Jetlag - can we expand this a bit, can only clearly see which bar is day 1 and 23 for my trip. Any context behind how it's calculated would be neat to see as well.

Edit: The Push notifications toggle doesn't load for me on firefox on android so i can't turn on notifcations. I also installed as a PWA and fails there.
