MetarTaf

I have put SAZN as first airport, and the app did not work anymore, open in watch and crash immediately

A lot of weather apps have too much information. This contains EXACTLY all that you need. Nice work. ( and it does work in the UK )

It’s great when it works. Put in an airfield that doesn’t have meters and it just opens and immediately shuts down. Also go to info for altitude etc and you can’t get back out of it.

Doesn't work in the UK???

I absolutely love this app on my Series 4 Apple Watch. It is perfect for ‘at a glance’ weather updates and forecasts with the included complication. Exactly what I was looking for and remarkably free. However, the colour convention for METAR reports is normally green for VFR, blue for MVFR, red for IFR and pink for LIFR. This doesn’t hold true in your app.
