If it only used iCloud, it would be perfect.
This app outshines the others in several ways!
The first is its interface. It gives you both form (clean + pretty) and function (all the “basic” info and more). And the customizability is spot-on. You can also save multiple locations, including your present (GPS) location.
The second is integration with Mac OS. Besides its ability to run as a traditional app, it also offers a Notification Center widget, as well as notifications, not to mention a Menu Bar option. And again, user customizaiblity is perfect.
The third is its complete cross-platform availability. It’s available on Mac OS, iOS, and tvOS. (Watch OS as well, though I don’t have an Apple Watch.) On iOS, the functionality is identical to Mac OS, right down to the Notification Center widget.
Unfortunately that last strength reveals a weakness: no cross-platform synchronization of cities (e.g. via iCloud). Other weather apps for the Apple ecosystem offer this functionality, but not Weather Live. So if you like to track the weather in multiple places on multiple devices, you’ll have to manually re-enter and update those on each and every device.
One other nit is that Apalon doesn’t state the source of their weather data. I contacted them abut it over a year ago, and I recall them saying it’s location- (nation-) dependent. Unfortunately I can’t recall their US source (possibly AccuWeather?).
JTK Awesome about Weather Live, v1.9
