New in 1.2: • Known runs — famous named stretches on a river now show right on the map. Tap one to fish it or save it to your own list. • Mark your own runs — drop a pin on your exact spot, give it a name, and it's saved for next time so conditions read from that precise point. • Every section of the report now collapses, and the app remembers how you left it. • Added the Ottauquechee River in Vermont. • Fixed the status bar overlapping the top of the screen on some phones, and made live hatch reports post more reliably.
