More about Lens

Lens audience segmentation

Create an extremely specific audience segment according to filters like game ownership, playtime, achievement completion, and more. Once created, an audience segment can be explored via graphs and trending lists, but also applied to any game in order to see all kinds of data on how the two intersect.

Yearly achievement activity

The yearly achievement activity graph shows how the total achievements earned by players in a game are spread out over time, divided into years. It is displayed as a relative percentage of all achievements earned.

The new users over time graph shows the rate at which a game reached its current playerbase using the time when a user earned their first achievement. It is a rough approximation of lifetime sales. It is displayed as a relative percentage of all owners.

User interaction

The user interaction graph shows interactivity data with up to three values. The first is "Played" which shows how many players have played the game for at least a minute. The second is "Active" which shows how many players have last played the game recently (2 weeks). The last is "Perfected" and shows how many players have completed all the achievements for this game, provided the game has achievement support (otherwise this value will not show). All three values are X% out of 100% where 100% are the total owners of the game.

Concurrent players

The concurrent players graph shows how many players were playing a game at a given time, sampled from Steam. If only a date is given, it was a point in time on that date, not a peak or a sum of players. No internal PlayTracker data is used.

Playtime distribution

The playtime distribution graph showcases the distribution of users according to their total playtime, capping out at 100. It is displayed as a relative percentage of all owners that have that many hours of playtime. The maximum number of hours shown includes everything above itself.

Popularity over time

The popularity over time graph shows PlayTracker's own "Popularity" metric for a game over time. "Popularity" is calculated from values like total owners, active owners, concurrent players, and more. An active owner is valued much higher than an inactive owner in "Popularity" calculation. It scales linearly - there are no diminishing returns.
