In short
Dynamic segmentation is grouping users by rules that are re-evaluated as their data changes, so membership updates on its own. A user joins a segment when they meet its conditions and leaves when they no longer do. It contrasts with static segments, which are fixed lists captured at one point in time.
Why it matters for apps
Standard user segmentation often means a fixed export, such as "users who signed up in March". Dynamic segments stay live, so targeting always reflects current behavior.
- Static vs dynamic: A static cohort answers questions about a fixed group over time. A dynamic segment answers "who matches this right now?".
- Behavior-based: Rules like "no workout in 5 days" or "reached level 3" let messages and rewards follow what users actually do.
- Less manual work: No one needs to rebuild or re-upload lists before every campaign.
- Common mistake: Overlapping segments that send one user several conflicting messages. Set priorities or exclusions between segments.
Industry examples
A fitness app keeps a live "lapsing" segment of users with no workout in 7 days, and users leave it after their next session (hypothetical).
A banking app keeps a live segment of users who have not set a savings goal and shows them a setup challenge (hypothetical).
Build it with StriveCloud
In StriveCloud, segments target users by attributes and behavior, and they update as users act. They scope leaderboards, challenges, rewards and messages, so a user who meets a rule sees the right content without a manual list. Combined with event-based stats, segments can follow windows such as the last day, week or month.

Frequently asked questions
What is the difference between static and dynamic segmentation?
A static segment is a fixed list captured once. A dynamic segment uses rules that are re-checked as data changes, so users move in and out automatically.
What is an example of dynamic segmentation?
A segment of users with no activity in 7 days. A user joins it after a quiet week and leaves it as soon as they come back.
Why use dynamic segments for engagement?
They keep targeting current. Messages, rewards and challenges reach users based on what they are doing now, not on an old export.
