There are a few tools you can use to set up your feed on Instagram. The most popular are Tailwind, Plann, Later, Hootesuite, Buffer, Loomly. There are others but these have been around a while and work well. Now that automated scheduling is available it's really up to you in terms of what to use.
Choosing a bigger tool that allows multi-use to other channels gives you more bang for your buck. With Buffer you can post to LinkedIn, Facebook, Twitter, Instagram, and Pinterest. With Tailwind you can post to Instagram and Pinterest, so it's more limited but it has a more focused and robust set of tools to visualize your layout.
It's worth doing a google search and testing free trials to see what works for your needs. If you're focused on Instagram and getting a lot of business lead there or building an audience it may make sense for you to choose a tool like Tailwind or Later specifically for the robust tools.
Feel free to connect with me if you'd like a tutorial on these tools and their differences related to your social media goals. Instagram is an amazing platform, my favorite! So I'm happy to help. :-)
