Asking for feedback (1) Fork the project! (2) run the rails server (on the terminal) (3) possibly open the code for review

Thank you for your help in advance! My questions are below:

------------------------------- open-source (specific) Qs -------------------------------

1. Does this app seem ideal for a traveling user? 2. Which would be more accessible to travelers - having this App built as a (mobile) app -or (iPad) website? 3. Does the design excite(!) the user to keep scrolling? 4. Is one feature enough? 5. CON: the app won't run in real-time - since it is pulling from API. Can anything be done to compensate for this? 6. How would I go about writing a TDD - on an API? 7. Is this code efficient enough for my first open source project? 8. Was Ruby on Rails the best approach for this project?
