Extremely limited for free users. There is a paywall for everything and you'll only be able to use the app for a few min before being told to come back tomorrow or pay up. The plus side to this being mainly a pay-to-use app is it seems to keep the bots away. The down side to this is that you'll only be able to reach out to maybe 5 people before being pay-walled. The boost features dont seem to do much either, so if your paying money for more exposure you will be disappointed.
