I'm sure you will enjoy its experience. I have been using it since last 15 days and i'm loving it. I guess you know the minimum activity value to get rewarded.

How are actifit token rewards spread for actifit post authors?
Count Actifit Reward
5,000 to 5,999 20 tokens
6,000 to 6,999 35 tokens
7,000 to 7,999 50 tokens
8,000 to 8,999 65 tokens
9,000 to 9,999 80 tokens
10,000 and above 100 tokens

I recommend you to post the activity to steemit block chain at the end of the day. Keep actifying . Be healthy and be wealthy.
