My initial impression was that they are just https://steepshot.io on SMT made a little better. So I didn't really bother to even read the whitepaper. If I remember correctly, #steepshot gets 15% of the earnings. So they should be bringing in decent money to the project and it's actually a working project. It's not as good as instagram but steepshot can improve by the time APPICS do their "FULL ROLLOUT Q3-Q4 2018" Both their partners are ICO and marketing related. they keep 20% of the tokens for themselves (compare that to 15% cut from steepshot)

If I add something a little subjective I'd say the videos felt flat, bland and just shilling to cover up that they are just instagram with tokens on blockchain which should be far easier than creating DTube or Dlive(which had 0% beneficiaries last time I checked)

According to this comment from Dlive Admin they are going for SMTs too. I'd say wait for that. Dlive is an already working product.

IMHO investing in APPICS is as good as investing in SNAP. If you were one of the earliest to the party, you'd make good money with all the hype + discounted prices from the ICO. Personally I'd just set smartsteem to use my VP when it's over 98% and collect some passive income.
