Congrats on the launch. It's frowned upon to make sockpuppet accounts to upvote and comment on your own posts.
While I'm here, a little feedback: You're entering into a very crowded market. That's not necessarily bad, but you do need to differentiate your product from other bookmarking apps. You need a webapp or a browser extension to make this practical - I don't want to manage bookmarks separately on mobile and desktop. You mention the ability to add notes to bookmarks. Are there other key features I missed that differentiate your offering?
