Buffer app it's really easy to use. Exactly what I need to manage my personal brand.
I use buffer in Android and IOS and the link shortener works better in Android: it applies it even before saving the post in your buffer.
I particularly like the integration with Feedly. It's the perfect tandem!
These days you need to make sure that you stay connected and grow your own network. Engaging with my peers by publishing relevant content helps me achieve exactly that. However it's difficult to find time to do it, so being able to schedule posts in my own social networks is vital. Also Buffer alerts me when all posts have been published.
I have also used Buffer for freelance work when helping small companies managing their own social networks.
