But you'll have to act fast: Submissions close August 31. Last year's comp unearthed a bunch of cool apps (and location-based services were big), so I'm looking forward to seeing what pops up in September for public judging.

Users of Android devices will be able to grab a special judging app from the Android Market to download, test, and rank entries. The top 20 programs in the following categories (200 in total) go into the second round:

• Education/Reference
• Games: Casual/Puzzle
• Games: Arcade/Action
• Social Networking
• Lifestyle
• Productivity/Tools
• Media
• Entertainment
• Travel
• Misc

In the second round (roughly October), Android users will make up 40% of the vote, with a Google-selected judging panel accounting for 60% of the score. Winners will be announced sometime in November, while $USD prizes will be distributed as follows:

For each of the 10 categories:

• 1st prize: $100,000
• 2nd prize: $50,000
• 3rd prize: $25,000

Overall (across all categories)
• 1st prize: $150,000 (meaning the overall winner will receive $250,000)
• 2nd prize: $50,000 (meaning the 2nd prize winner will receive up to $150,000)
• 3rd prize: $25,000 (meaning the 3rd prize winner will receive up to $125,000)
