Simply Weather


This is a short-term weather forecasting widget based only on the current air pressure, its trend and the wind direction. It does not need an internet connection. I’ve seen it claimed that a forecast made around 09:00 is greater than 90% accurate.</p><p>The app is a software implementation of the Zambretti Forecaster ( produced at about the time of the 1st World War. There have been several software versions of the forecaster, this one is adapted from Beteljuice’s Javascript code (</p>


Added support for MARQ (Gen 2) watches. Built with SDK 4.1.7 (Version 1.4.3)</p><p>Tweaked forecast code. Built with SDK 4.1.3 (Version 1.4.1)</p><p>Reworked pressure history code. Built with SDK 4.1.2 (Version 1.4.0)</p><p>Tweaked air pressure display (Version 1.3.1.v)</p><p>Changed default method of reading air pressure sensor (Version 1.3.0.v)</p><p>Added choice of pressure (mean sea level/ambient).

I have uninstalled this app five times and it is still showing up!!! DO NOT INSTALL! I think this is spyware!

A fejlesztő válasza
2023. szeptember 10., simonletts

I'm sorry you're having problems. I've no idea why it won't uninstall, which is under the control of Garmin firmware, not me. It certainly isn't spyware - that wouldn't get through the Garmin vetting process. I'm a retired, now hobbyist, software engineer who does this for fun. Everything I've developed has been because either I've wanted it or someone has contacted me to request it. I have no reason or desire to write spyware.

2023. május 3. | Verziószám: 1.4.3

I love it! I love meteorology and this is just my style! Could you maybe tweak the app a bit that rainy weather will appear close or below to 1009 Mb, and not on 1016 when it is falling? It's unrealistic to have rain in such a high pressure, at least from where I come from.

A fejlesztő válasza
2023. szeptember 10., simonletts

Thanks for your review. The weather should follow the pressure as in the Beteljuice implementation of the original Zambretti forecaster. You can tweak the values from the widget's settings page.

Great app. Can it change display between celsius and fareniheight? Couldn't see it in the settings :)

A fejlesztő válasza
2023. március 20., simonletts

Thanks for your kind review. Glad you like it :) The temperature display follows the global watch settings. It'll be under System Settings. The widget uses whatever units have been set there. If there's a problem please contact me directly.

Excellent stuff, but can you implement some simple compass in the app. That would be awesome

Thanks for your review. I'd already been wondering about adding compass points. I'll take a closer look. Watch this space - but not too soon!

App seems to work well... Unfortunately I can't seem to change it from Fahrenheit to Celsius, so the app isn't useful for me

A fejlesztő válasza
2022. november 22., simonletts

Thank you for your review. The app should display whatever units you've set your watch to. You don't set the units separately. If your watch is set to Celsius but the app is still showing Fahrenheit please let me know. It's always better to contact the developer in the first instance if you have an issue.

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....

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!)

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.

A fejlesztő válasza
2021. december 29., 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!
