Welcome to Bitrig Hacks iPhone Duo Edition!
We're excited to have everyone hear to build some great apps for the new phone!
Requirements
Projects should use Apple's newly released APIs for iPhone Duo to build something that would not have been as compelling, or even possible, before.
Submission RequirementsA valid submission is completed via Devpost and must contain the following:
- Project Name
- Link to demo video
- Technologies used to make your project (example: Bitrig, Xcode, etc)
- New APIs / capabilities used
- Description of your project
Your final Submission must be made prior to 3:30pm Pacific. Any un-submitted, or draft entry not submitted by the hackathon deadline will not be considered by the Judges.
1. WriteupThe Devpost Writeup is your entry and is what will be judged. We want to know why your project makes the most clever/novel/unprecedented use of the new phone! A title is required. You can optionally include a subtitle, as well as thumbnail and card images.
2. Submission TracksAll submissions will be considered for the main hackathon prizes of first, second and third place. If your project uses RevenueCat, be sure to opt in to the judging for the RevenueCat award!
3. AssetsYou must include at least one screenshot, and a link to a video with a demo of your hack. Feel free to include any other assets of your choosing though!
4. Project DescriptionA full description of your hack. Include what it is, what it does, and how it makes unique use of the iPhone Duo!

Judging Criteria
-
Use of iPhone Duo
How meaningfully does the project take advantage of iPhone Duo's unique capabilities? Judges should consider whether the project would be significantly less compelling, or impossible, on a traditional iPhone. -
Originality and Creativity
How fresh is the idea? Does it demonstrate an unexpected or inventive way of thinking about iPhone Duo? -
Execution and Demo
How convincingly has the team brought the idea to life? Judges should consider functionality, polish, clarity, and how effectively the demo communicates the concept. A complete production-ready app is not expected. -
User Experience and Design
Is the experience intuitive, cohesive, and thoughtfully designed? Does the design feel intentional rather than simply adapted to the new hardware? -
Potential and Impact
Does the project suggest a compelling use case, product, or direction that could be taken further?
