And yes, this app is working locally

When I ran heroku ps I get this error

=== web (1X): `bundle exec rackup config.ru -p $PORT`
web.1: crashed 2013/08/09 19:10:11 (~ 8m ago)

Answer 1

These two lines seem to be indicating the problem:

2013-08-10T01:29:15.827320+00:00 app[web.1]: /app/config.ru:1:in `require': cannot load such file -- ./app (LoadError)
2013-08-10T01:29:15.827320+00:00 app[web.1]:    from /app/config.ru:1:in `block in <main>'

The app is trying to load your app.rb file, but it isn’t there. The fact that your app is working locally suggests that this file hasn’t been added to git. Add this file (and any others your app uses), commit, and then push again:

$ git add app.rb
$ git commit
$ git push heroku master
