Kann ja sein das das eine gute app ist aber mein Uhr braucht einen Schlüssel um es anzeigen zu können

Es tut mir leid, dass die App bei Ihnen nicht funktioniert hat. Sie benötigt keinen Schlüssel, sie ist völlig eigenständig. Es wäre besser gewesen, mich direkt zu kontaktieren, damit ich versuchen kann, Ihnen zu helfen... ... I'm sorry the app did not work for you. It does not require a key, it is completely self-contained. It would have been better to contact me directly so that I could try to help you.

Great update, your program that I call "Sam's weather " after me lol... is running perfectly... Thanks very much for the nice update that gives it that personal touch by renaming it to what you like.

Glad you like it Sam!

This is one of those widgets you don't realise how import it is to have. A weather widget that doesn't require a data connection to help predict the weather! I mean you ALWAYS have data don't you?? I thought not!! This widget does what is says and is pretty darn accurate too. and with the addition of Tempe connection and Ambient Pressure it is just perfect.. This is a widget I constantly use daily as I work and play in the hills and mountains. Seriously if like me you are in the hills and mountains regularly give this widget ago. You will love it and it will become one of your must have widgets.. This is honestly one of the most important widgets I have on my watch it has been so useful in my day to day life and job if my fenix died I would buy a replacement watch just to use this widget and yes I am being serious when I say this. Like I have mentioned I work and play in the Hills and mountains and am often without a data connection as a result so most of the other weather widgets and apps become useless due to the need for data connections, this is where this widget comes in and just excels!! I am amazed at how accurate it is even late afternoon it is probably as much as 70-80% accurate which given how it works it friggin awesome and as good as standard weather apps etc... Thank you Simon for bringing it to our devices. In my mind it is without adoubt one of the most important widgets for our watches out there, It is a must have for all outdoor enthusiasts . Outstanding work and thank you for listening to our feedback and requests....

I think Andrews Idea of Garmin "tempe" information would be just perfect!...Real temp info added!.. I'm still finding this pretty accurate, I so often don't have my phone with me.

Thanks for confirming the accuracy. I am looking at adding temperature - it was always on the "roadplan" to be honest. Using the Contact Developer link is probably a better way to make comments and suggestions, then I can reply personally (and ask for help with testing!)

Welp it works well, very happy with it and thank you for creating this widget at my request. -Thomas

All working after updating (Fenix 6x Sapphire BLK DLC, it does seem to be very accurate,after testing a few days and very useful without phone, this was a brilliant idea to bring to a watch.

31. Dezember 2021, simonletts

Thanks again :) Great to know you find it accurate. My experience is that it's generally pretty good but occasionally just wrong. I'm still not sure I've got the swipes/button presses quite right!

I just had a quick read, very interesting, this works without phone connection then?, using wind barometer and direction and the algorithm? 90% avg 12hr forecast Awsome, thankyou.

Antwort des Entwicklers
29. Dezember 2021, simonletts

Thanks. No, no phone connection. It uses barometer current value & trend, wind direction & time of year (6 months summer, 6 winter). I've read in 2 places it's supposed to be over 90% accurate but I don't know who made the original claim, when or where!
