By Day 7, retention dropped to 15–25%, meaning a significant portion of users were lost too early.


For 10k users, this translates to up to 7,500 lost users, which could cost $7,500–$75,000 in CAC alone (conservative estimate, excluding operations).

Customer satisfaction dropped to around -80% after sessions, far exceeding the tolerable -10% threshold. This highlights a major experience gap that risks long-term retention.

Tasks were taking an average of 4t, double the acceptable 2t limit based on priority, complexity, impact, and emotional friction. This points to inefficient flows causing user frustration and drop-offs.

Projected Day 7 retention lift: +35–45%.


High-growth apps typically see 5–10% improvement from UX audits, so this reflects the potential impact of addressing key friction points

Customer satisfaction expected to improve significantly, with early signals showing ~30–40% uplift. Even a modest increase at this scale can positively affect product engagement and revenue.

Average task completion time reduced from 4t to under 2t after optimizing user flows. Shorter, smoother tasks are linked to higher retention and engagement over time
