This is such a cool little tool at dobber hockey. It's a draft and lottery simulator all built into one. I don't know if it works on your phone or not, but it's great on my computer.
draftsim
You can choose your team that you want to be the GM for the draft, set different parameters with a slider such as the randomness of the picks by the computer for other teams, set team needs for the draft, simulate the draft lottery, have the computer simulate other team picks until it's your turn with your team, then it gives you the list of players to choose from and even details and stats about that player, including scouting reports. You can simulate the entire draft through all 7 rounds, then it gives you a list of your picks at the end. You can even try and trade draft picks (it assigns a number value to the selection for each pick, and you are not allowed to cheat, the value of your picks must be higher than the value of the other team's picks to make the trade) and then do the draft. Give it a try. Good fun while we wait an eternity for the draft in late summer.
