I have updated my Mobile Development Primer with more recent relevant content.
Many people, particularly individuals or startups, approach me who have an idea for a mobile app but have no experience of creating software or mobile apps. This site contains thousands of posts, created over 10 years, with lots of insights for startups. However, the blog-style format isn’t very digestible for people who ask me how to get from idea through to development.
The Mobile Development Primer lists some of the things startups should be thinking about when considering mobile development. It links to relevant posts on this site to give more detailed insights into specific areas.
