Sleeper is a fantasy league app for playing fantasy football and basketball (and I guess other sports). I've been in a fantasy football league and the last one I was in was probably like 20 years ago.

It's got a fairly good web interface while the iPad app is less intuitive though more colorful. Although even the web interface I've done things wrong because there is no help or user guide to how to use the UI, nor to what the various statistics mean or timing of when you can change players or what's the tiebreaker for playoff seeding. Luckily it's mostly intuitive but frustrating at times.

What I really like is pretty much all the information is there. Each player has an expected points for the week (accurate or not, at least it give me something). Each player has a player report that's updated a few times per week from various sources. Each player shows their official injury status though you have to read the player reports since NFL teams fudge injury status. I love that it shows % of teams that have drafted a player and % of teams that are starting that player -- I can pretty much do the same and do pretty well (though check to make sure the player is actually going to play that week). Basically I can spend 15 minutes looking through the reports and setting up my lineup and not have to hit the Internet for information.

Longest thing was doing the draft, which took a couple of hours. We did a draft where you have a pool of money then it's (1) next team picks a player (2) teams bid in real time. You can let the computer do all the bidding though it is too aggressive and will blow through your money fast. Still, I let the computer pick my player and do bids up to a certain amount and the team I drafted was surprisingly good considering I didn't know half the players.

Anyway, other than no help system it's a fairly impressive fantasy football web site.
