dipdig

Hi, dear hunters, I am a newbie of web development. Now let me introduce my first web app: Dipdig. It is an online business model canvas edit tool, which might be helpful for business idea analysis. After developed for several weeks, I begin to doubt it. "Is this the tool that people need?" Therefore, even though it is still under development, I decide to launch it and seek for some professional advice on app development. So, that's it. All suggestions are welcome.
