Sometimes this app has a delay with the post scheduled. But in general it's a good app
It has worked pretty well, till now. I can schedule several post for a day (but there is a fact: I cannot schedule for hours with minuts that end on 5. For example: If I want to post at 20:45 I have to change it to 20:40 or 20:50). Anyway, it's great.
Now you can post images to your Instagram Stories
