Normally not a bad app, but not that uncommon for it to indicate data not available on the widgets. Also, yesterday, while getting 0.4" rain the home screen of the app only showed cloudy, it did not show Rain rate, accumulation, as the app descritption says and as it used to. To find that I had to tap on the home screen and look at the stats. Not that helpful.

Really like the weatherstation and app. They just need to come up with some method of toning down the lightning alerts. Maybe an option to allow 1 per hour? Woke up this morning to 16 lightning alerts. Otherwise it's great, can't recommend it enough. Also, since last update, it regularly says " no recent observations". Hit refresh and it's fine.

Thanks for your review and feedback, Dylan! Lightning alerts are only sent every half hour or if the storm is getting significantly closer to your location. If you're running into an app issue, please reach out to our support team for assistance: help.tempest.earth

This is my updated review. I updated it to 4 stars this time for performance. I love the simplicity of the unit. It works very well. 4 stars and not 5 only due to the GUI when you want to zoom in or out. The use of +- control box is lame and does not track what you are zooming in on, requireing you to thumb back to your target each time + or - is pressed. Just make it like all other apps by pinch and squeezing to change the zoom. Still love the station. Buy it.
