the industry standard for evaluating retention rate is at 90 days, only 1 month to go but here is the current situation:
60 days March 3, 2017 - May 2, 2017
gravity @ <0.4% retention. its doing worse than majority of games / apps
Oh, I didn't notice they reached 10k downloads. The bad news - only 18 players this week so far, typically goes to about 40 towards the end of the week. And last review was a month ago. They are probably buying just downloads now, no more fake reviews.
I've also noticed that a lot of the talk in their community has switched towards trying to sell the masternode aspects of the coin rather than the gaming side of things while there is a (predictable) lull in development and the gaming world waits eagerly for Gravity to be 'finished'. They apparently started a closed beta for the next update to Gravity last week, so I guess anywhere between now and six months time we might finally see the 'completed' version let loose.
