Although I no longer use Instagram, I still have an account there, and from time to time I like to see what people I know post there. To do that I always used the website in the browser. However, their website is not fast and has some bugs. Recently, I came across the alternative Instagram client “InstaGrabber”. While it sounds like a simple Instagram image downloader, it has a lot more functionality. It allows viewing your feed and stories of people you follow. To enable this, you can also login.
It is completely free software available on GitHub and installable via F-Droid.
