Five apps I use religiously that my Instagram would suffer without.
Take your Instagram stories to the next level with Unfold. This app comes with a variety of preset templates that include framed borders, different text options, color choices, etc. It's almost like scrapbooking but way faster. Trust me, every time I post a story using one of their templates I get questions about it!
Canva is the perfect app to use to make Instagram story highlight covers. Check out my article for a step by step tutorial on how to make these.
Plann is most useful for playing around with an aesthetic by allowing you to "plann" what to post next and see how it incorporates into your feed.
If you edit your pictures on anything else... you're doing it wrong.
Ever take a picture and think "if only JUST the background was a little brighter" well Snapseed is a photo editing app that lets you play with the brightness and exposure of selected areas in the picture.
