Hi all, I looked around on BHW but couldn't find a proper thread on mobile app developments. (In case I missed any, i'd appreciate if you could guide me to the appropriate thread). This post is specifically for those who have experience in building or managing mobile apps. Anyways, for the year ahead i'm looking at trying out building some mobile apps. I have the idea in place and targeting a very niche market. Can you guide me to the following: 1. Is there a guide/pdf or a forum thread that I can start off with to learn more about app development 2. What are the start up costs for a mobile app (ex. for websites we know that there are domain/hosting/design costs, etc.) I know that iTunes and Android require some fees, but are there other monthly costs 3. How does advertising work with mobile apps? Is it similar to adsense? What about apple apps that serve ads? Any criteria for signing up for the apps? How are payments made? 4. What is the average cost of getting an app developed? 5. Is there a list of what to do and what not to do when building a mobile app? 6. When I ask for quotes from a developer, what things should I consider? Just developing the app? Do they also do a thorough testing to detect any bugs? Thanks a lot in advance and once again sorry that I couldn't find the info myself.
