I have seen so many failures in application and app design, but this can be avoided. If you are designing a mobile app, many development firms will push you to develop the app first.

These tips help you launch a successful, affordable minimum viable product (MVP) and keep your maintenance costs low, even in an app environment. This short, 2 minute video, will give you some tips.
