Promising, but lots of glitches
Note: The review above is from a year ago and the devs response is from yesterday. Take from that what you will.
Response from developer
Date issue has never been reported, we do allow for belt entering and verifying, we do have a training tracker that allows you to see sparring time vs total training time, we have an "Events" section designed to showcase things such as seminars, tournaments, etc., and our "Hidden Profile" mode explicitly says to only turn on if you do not want to interact with any social features.
