What is Instagratify? The hashtag-based tool enables sharing of images, text, albums, and video, from Instagram to any number of other social accounts - including your website (probably the most important feature). The tool also permits you to stitch images into a GIF or create a video sideshow - all with the use of a single hashtag. I've not posted to Facebook, LinkedIn, or other networks in years, but you wouldn't know it by reviewing those platforms.
Scheduling Instagram posts to 'other' social networks is easy. From within Instagram, simply include a 12-digit timestamp in any portion of the post that is snipped (after the space-dot-dot-space pattern). So, #202306091000 will send 'around' 10am on the 6th June (you normally wouldn't include the timestamp in the visible portion of your post).
Stacking is a type of scheduling feature which isn't really 'scheduling', but rather 'spacing'. If you post multiple Instagram images in quick succession, you may want to space them apart. Using the hashtag of #stack with each post applies an interval as defined in Yabber (the wait time is platform and account specific).
Instagratify is a very useful social tool that's ridiculously easy to use. If you're a client and wants a little refresher session, let me know and we'll schedule a quick discussion.
