A free program for Android, by Pishtech LLC.

It’s a five-day fishing derby, but it has a twist. You can only fish one day, and you must collect the cash from the weigh-in for the fish you catch. You’ll also have to make sure you have enough cash to pay for the necessities, including a portable shelter and heater. If you don’t have enough money, you’ll have to rely on other fishermen to give you some. You’ll also need to be aware of what bargains you can get, as well as what you can trade with other fishermen.

You’ll start the game with some basic gear, but you’ll have to work your way up to getting more sophisticated equipment as you become a better fisherman. You can also use the game to learn about fishing.
