Based on the metar text they are all actually about 1 day old. Not much value. ### 1/5 — Seems to be dead *2025-03-05* 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. ### 5/5 — Great app again *2024-01-23* Very nice thank you . Once again the prog chart is back and the wind aloft . It was worth hanging out for the fix. Thank you guys again . ### 1/5 — App no longer works *2024-01-08* 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. ### 4/5 — Still Supported? *2023-12-27* The Prog Charts are not readable. Otherwise a great resource. ### 4/5 — Now partially working, for METAR and TAF only. Better than nothing!— *2023-11-03* Broken by AWC update, October 2023. Will keep checking! —- Great app and thank you for keeping it updated! All relevant information and all in one place. I recommend it to other pilots frequently. Thank you! ### 3/5 — Error message *2023-10-19* “Problem parsing w Server” keeps popping up. There is no way to contact support or to try to fix it. Have removed and redownload it rebooted iPad no help. It does the same thing on my IPhone ### 2/5 — Latest FAA update broke the app *2023-10-19* Broken by AWC update, October 2023. Will keep checking! —- Great app and thank you for keeping it updated! All relevant information and all in one place. I recommend it to other pilots frequently. Thank you! ### 5/5 — Great app *2023-05-08* Great app and thank you for keeping it updated! All relevant information and all in one place. I recommend it to other pilots frequently. Would love to get the headwind/tailwind calculations back when you get a chance :) Thank you! ## Frequently asked questions about NavMonster ### What is NavMonster's current rating and how many ratings does it have?
