I think $20 is a great price point (honestly I think you have room to grow) but you need to give people an opportunity to experience the benefits of the product.
With WWDC looming there is a chance trials might get announced. If not I'll probably do something.
To directly answer your questions: it is GitHub only. I see the main benefit vs other tools is a streamlined and focused workflow for reviewing and collaborating on pull requests. Also the iPad form factor is a nice change of pace vs reviewing on your computer.
The iPad seemed like a good alternative to reviewing code on your computer. You can get away from your desk, and change your mindset.
Turns out, in that case, organizational structure had better precision and recall than any of five other models (code churn, cycolmatic complexity, test coverage, etc.)

The app itself is still missing some things for my particular workflow: I'd like to have visibility on incoming code that's not part of pull requests. Like simple pushes to branches.
I'd also have the possibility to unsubscribe from repos directly from the app.
- Comment preview.
- Symbol row on top of keyboard (such as ` and Markdown symbols.)
- Font selection for code view.
- Some indication of which line is currently being tapped in code view.
Also, I couldn't get the app to list pull requests from a repo with Issues disabled. A bug, maybe?
Regarding font selection, which fonts would you like? I'll have to bundle the fonts with the app, so I'd like to hear what people are into. Right now it uses Meslo for source and Avenir everywhere else.
GitHub recently fixed the unable to fetch PR updates when issues are disabled thing. You aren't using GitHub Enterprise are you?
I'm definitely not using GitHub Enterprise. From what I've seen in the connection log, pull requests from repo with issues disabled are completely missing.
Also thanks for the app! I can now finally do a code review on a toilet. Yay!
The web page doesn't give me any real hints. The App Store listing only shows in the title that it's a GitHub-only thing.
I don't suggest overloading with unnecessary detail, but it would be nice to know something before spending $20.
Why is a code review app rated as 17+?
I'm not sure if this would work for your app, but maybe you could restrict access to just github.com? I'd also second a video or something more insightful on the landing page of the app's website.
