Stopped working

I used to love this app, but it recently stopped working and won’t update weather

METAR issue

METARs all show as 28 days old. Based on the metar text they are all actually about 1 day old. Not much value.

Seems to be dead

As of now 4 March 2025 22:35 (UTC-8), the data have not been updated in 24 days. I have switched to the app Metar-Taf which requires a one-time payment. (I am not affiliated with that app other than as a user.)

This is disappointing as NavMonster was refreshingly simple, quick, and reliable. I hope it comes back some day.

It was worth hanging out for the fix.
Thank you guys again .

App no longer works

I used to use the app regularly but over the past several months it’s become unusable mainly due to none of the Prog Charts being viewable. I no longer use this app and instead use the online website.
