Yes, it's called eSteem.
Read the terms for it and make sure you are ok with them. You are granting the developer part of your post/curation rewards when you use it. The permissions (camera, contacts, location, etc ...) are normal for a social media app.
DO NOT LOG IN USING YOUR PASSWORD OR OWNER KEY. Whenever you use a 3rd party app only log in with your PRIVATE POSTING KEY.
