The app does not do a whole lot right now. Most importantly it notifies me when someone submits a new project so I can review and approve it. In a future version the app will send push notifications to keep you informed about your projects. Building a mobile app is hard. You'll have to excuse me if I don't make an Android mobile app right away as I don't have a phone to test on.
I hope you like it. At this point I want people to submit projects and give feedback. I have a slew of minor updates coming up and I'm hoping to improve the user experience while I continue outreach for the website. If you have ideas about this, let me know.
