Finally, a real fishing tool for iPhone that's not a game! Use SalmonSize on your iPhone to estimate fish weight. Great for fly fisherman to get a streamside estimate while steelhead is safely in water. Dual sliders allow you quickly dial-in length and girth of your fish, watch the display instantly change. SalmonSize uses a well known algorithm for making estimates. Displays weight in either English or Metric measurement systems. Salmon/Steelhead inhabit some of the most remote places on earth, and this App is for that - it works with no internet connection. Less than the price of a plug or package of hoochies!
