天気と昨日

I am a weather geek and spend a lot of time outdoors and watching weather and it’s forecasts and trends. Have been looking for a simple app/way to get stats on past weather and generally yesterday (as a reference for today’s forecast). Simple App with a lot of good details. Not sure if Pro version provides additional historical data as free version only goes back one day. Great little app - thank you! (And please explain what pro unlocks -thanks!)
