Join us this Fall, for the largest Mobile App Hackathon, ever. Over 30 cities and 6,000 developers will join in to build stronger developer ecosystem around the world.

What makes AppHACK the best hackathon series on the planet? - Developer bootcamps to teach Android and iOS development. - 100's of developers and designers at the event for you to work with. - Free tickets for all developers/designers who solve our riddle below. - Incentives throughout the event to encourage teams helping one another. - $100'000's in sponsor prizes. - Fun toys and games spread throughout the venue. - Great food and lots of it. - Alcohol in most locations (where venues permit). - Coding through the night (with pillows). - Top teams entering the HACKcelerator pre-accelerator program. - Sponsor awards, breakout sessions, and post-event parties - Mandatory Demos. Banning of slide decks. And code reviews to ensure winning teams are within the rules.

What should I build? We want to see you build a mobile application. It can be done in HTML5, on iOS, Android, Appcelerator's Titanium etc etc. What matters is that it's mobile first. This is where we see the majority of opportunities right now and a place where your simple hackathon project can have impactful applications. Feel free to connect your app to wearables, in-car devices, and other hardware integrations that are being formed today.

Who should attend? Junior developers looking to improve their skills, senior developers looking to jive with budding members of the community, designers of all skill-sets, and serious entrepreneurs that can add value to teams. Never built on Android or iOS before? Fear not, we'll do our part to have teachers on hand throughout the hackathon to help you get going with these new and needed skills.

How is it judged? We're doing things a little different this time. Say goodbye to power-points. That's right, no power-points whatsoever. To present at AppHACK you must DEMO. Period dot the end. And everyone who wants to win AngelHack will have to demo their product for at least 30 seconds. Projects will be judged on a combination of originality, technological difficulty, viability and usefulness. We want to see new ideas, ideas that are useful, ideas that solve big problems, ideas that could potentially make money and ideas that get people excited.
