What does this mean on Happn?

[Anonymous]

What is the difference between [active today] and [active a few hours ago]?
Active a few hours ago clearly indicates when a user was last active. So what does active today mean, that at one point or another during the day they may have logged on?

Active Today means they were Here, dear.
Active a Few Hours ago, Not giving you any Specifics on the Time but "Just Seen" If you Know what I Mean? xx
