Show HN: League Warrior

It's semantics, but to me they have totally different meanings!

Here is some of the things I think you should improve upon:

1. The sliding UI on register page is a bit confusing. Perhaps add some UI guide tutorials? You probably know this, but I want a easy way to invite my Facebook friends!

2. Since you know the available field locations, you should show it on the map to encourage the user to make the "Create Game" UI smoother.

3. There is a lag after completing the "Create Game" form.

4. Instead of just games, where can I find out about leagues around where I live?

5. Are you thinking about having people check-in during the games?

6. This might be complicated, but I wonder if it would be worthwhile to add score keeping and gamification feature with this app, to build reputation and game records. With this record, people could challenge each other.

7. Is e-sports going to be added in the future?

One thing that I've noticed for pick up soccer in the Bay Area is that there are a lot of games listed on meetup.com, but probably way less than 10% of them, since I personally know of a bunch that aren't on meetup. There are also several other websites that I've found on Google over the years that list some pickup games, but still, nothing that is anywhere near exhaustive.

The problem that you guys might have is that your app ends up as just another small subset of the games around. If you could figure out how to become the definitive and nearly exhaustive list, there could potentially be a lot of value in it. Think about how Yelp is useful because it has all the restaurants, and how useless it would be if only 10% of the restaurants were listed.

Reviews of ongoing games might be useful, as would ratings of skill level and information about the playing surface or number of fields/courts that people could search on. Another thing is that some ongoing games are already pretty full, so some sort of status that somebody could set for the game in terms of "need more people" or "near capacity" could be useful.

Lastly, it's been my experience that an ongoing pick up game might have 20-30 people in attendance, but only 1 or 2 actually check in, so you don't want to necessarily count on everyone checking in.

Your biggest obstacle is probably going to be reaching critical mass. There are a lot of ways to help you achieve that - in this instance I'd suggest going the OKCupid route. What they did was offer a supplementary service (quizzes) that was fun and relevant for the users even before they reached critical mass.

You just need to make the app as useful as possible for existing pickup games. With the push notification reminders it's already useful but perhaps you could add score keeping (I'd love to know what % of the time I'm on the winning team) and easy group communication (without excluding non iphone users).

One small thing, had some issues with the register screen returning me to login screen after I pressed the register button (I know it's in beta, just pointing it out :) )

Those people drive me crazy.
