Overview
Retention rate measures the percentage of users who return to an app on a specific day after install, with D1, D7, and D30 retention being the most critical benchmarks.
Retention Rate : Full Definition Retention rate tracks what percentage of users who installed an app on Day 0 are still active on a subsequent day, Day 1 (D1), Day 7 (D7), Day 14 (D14), and Day 30 (D30) are the standard cohort milestones.
It's the foundational engagement metric for mobile apps and a primary predictor of LTV.
D1 retention (typically 20–40% for well-optimized apps) measures whether the first session experience was compelling enough to bring users back the next day.
