Onetime.

This has been for years my go-to app for checking timezone differences with family and coworkers and I have recommended it over time to many people. However, I recently started noticing that data for some cities is completely unreliable. Try adding Taipei or São Paulo and the app will put them in the same timezone as London. This made use it way less since I’m always checking if the data is accurate, particularly during daylight saving time when countries adopt different policies. Please fix this! I love the app (and I would pay for it) but without reliable data it is completely useless.

Love this app. But the Timetravel feature stops working when certain cities are input.

This app is simple, and yet so incredibly useful. It does what it says on the tin, and does it with great style. The interface is simple, but very pretty, and has some nice touches, like the way the day/night boundary jiggles when you pass through it. I am surprised this is free. You can’t go wrong with this app if you need to keep track of times in more than one time zone.
