Does an app like Instagram need a good website?

Question

Android

Those. if the main application is smartphones, tablets. So do you need a version for access from a PC?

Answer 1

Estimate the size of the main and casual audiences.
For example, I do not use the same Instagram. But sometimes someone sends me a link to a photo there and I need to quickly open it. I will not install the application for the sake of this - I will use the site.
What does "good" mean? If you mean functionality - no, on the contrary, it’s better for me that the site is as easy and fast as possible. Opened, cursed on the plate to install the application , looked, closed.
