Most mobile game studios track D1 and D7 retention separately. But the ratio between them — D7 divided by D1 — is more diagnostic than either number alone. It tells you not just that retention is low, but where in the player journey it is breaking down.
This is the framework practitioners use to diagnose retention problems during soft launch before spending more on UA.
How to Calculate the D7/D1 Ratio
The ratio describes the shape of your retention curve. A ratio of 0.35 means you are retaining 35% of your Day 1 players through to Day 7. The question is whether that is normal decay or a signal of a specific problem.
How to Interpret Each Ratio Band
Real Examples
| D1 | D7 | Ratio | Diagnosis | Fix |
|---|---|---|---|---|
| 42% | 11% | 0.26 | FTUE problem | Fix end of Day 1 experience |
| 40% | 15% | 0.38 | Core loop problem | Strengthen Days 2 to 5 content |
| 38% | 19% | 0.50 | Normal decay | Check D7 vs genre threshold |
| 35% | 21% | 0.60 | Strong arc | Focus on CPI and creative |
Why D7/D1 Is More Useful Than D7 Alone
Two studios can both have D7 of 15% and face completely different problems. If Studio A has D1 of 30%, their ratio is 0.50 — normal decay, the core loop is working, D7 is just at the lower end of their genre threshold. If Studio B has D1 of 55%, their ratio is 0.27 — FTUE problem, players are engaging strongly on Day 1 but not coming back.
Studio A needs to work on UA. Studio B needs to fix their Day 1 experience. They have the same D7 but completely different diagnoses. The ratio is what separates them.
What the Research Says
The D7/D1 ratio framework comes from Lancaric's Soft Launch Bible (2025) and Traplight's D3/D1 analysis (2022). The bands described above are the practitioner consensus on how to interpret the ratio across mobile game genres.
