Buffer offers a free plan with up to three channels and unlimited scheduling, making it ideal for small businesses or individuals who only post occasionally. It's also one of the best Instagram schedulers in terms of user experience. Iconosquare is another top option, offering extensive analytics and monitoring capabilities for professionals and large-scale businesses. Hootsuite is a full-featured social media manager that can handle multiple accounts, including Instagram, but its pricing may be too high for some users. Later is a great personal Instagram scheduling app with a push notification workaround for posting to personal accounts. Ultimately, the best Instagram scheduler depends on your specific needs and preferences.
