Congratulations! I'd love to hear more background about the motivation for this app and the dev process. Are we talking 5 months of full-time development or 5-months as a side project? What motivated the project? What are your future plans?
I'm a huge Instagram user (I created Pinstagram) and I would see a lot of people posting quotes. Quotes is also another passion of mine. I love inspiring quotes and I see a lot of people sharing them so the idea of mashing 2 of my favorite passions - photos (instagram) and quotes seemed really natural.
Future plans include mostly refining the product - adding more quotes, improving the UX, providing more themes (as in app purchase as well as free).
Challenges include: marketing in the app store social media marketing getting users / downloads making sure I build something people want
