Just as explained in this post :

APPICS Token Swap & Customer Platform
Current APPICS token holders can now register for our token swap to receive APX tokens at token.appics.com!

This is how the process will work:
Token holders login with their existing account at token.appics.com
On the platform, you then register the steem account on which you'd like to receive your Appics tokens
After the registration has been open for a few weeks and everyone entered their Steem accounts, the SteemEngine team will then distribute the tokens to the respective Steem wallets
Users will then receive the steem-based appics tokens in their steem wallet. Then you can power up the tokens to increase your voting weight in the appics app - and from then on, you will also start earning both APPICS tokens and Steem tokens inside the appics app!
