social media tools

hello everyone , i'm wondering if there is any free software for managing posting time on social media
something can post for you for exemple every two hours
i need something like Nextpost 3.0 but for free

I recommend Hootsuite and Buffer. They are both free and both are easy to use. You can manage your posts from social media sites and you can schedule posts in advance so it's really helpful in your Social Media Strategy. You can plan your strategy easily with these tools.
