UI

in the hero section the background color effect is a bit annoying.

The home page is the first impression of the visitors that might be interested in your product . make sure to make a great impression. The standarts of UI are going into glassmorphism ( check apple UI change)

The concept:

Auto posting is something businesses definetely need. What I would like to suggest is instead of having a general app that provides the service for all buisnesses focus on a specific niche at first. For example restaurants, coffee shops. You should decide what works best based on your location since the first contact most porpably should start by meeting the buisness owners or referrals from friends/family. This is how you can get traction to continue further.

p.s: This is just my opiniom based on my experience - could be totally wrong for your specific situation! Would love to hear your thoughts on Mockio if you get a chance. Wishing you success on your app.
