It would be nice if an app pulled atmospheric data from your location, if gps is enabled. I would love to be able to consolidate data on my laptop along with GPS data from my Lowrance so that I start to see a picture when I am off the water. Follow that up with being able to search on body of water, atmospheric data and be able to search your prior fishing trips. That way I would know if I am headed to Fork on a cold day with a dropping barometer... this is where I caught them and what I caught them on.
that's great idea
If you have an active data connection you could get all weather data you need from the closest weather station to your location. if not you save the coordinates and later query a weather database to get all that.
