What changes

Daily streak systems are commonly cited for an 8–18% relative lift in DAU, with diminishing returns after week three.

When this tends to work

• Conditions similar to: Mobile F2P with sessions under 10 minutes, 2021–2025
• You can measure Daily active users (DAU) reliably
• The intervention is implemented consistently, not half-measured

When to be careful

• Your audience or product differs materially from the cited context
• Compliance costs or second-order effects outweigh the lift
• Evidence label is estimate—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
