With a 4.66/5 rating from 615.8K reviews, it delivers strong user satisfaction. > **Bottom Line:** Flat Equalizer - Bass Booster provides high-utility audio amplification, but the recent shift to subscription-gating for legacy users threatens the retention base, so the team must prioritize stability and trust-restoration to prevent mass churn. **Best for:** Android users seeking to improve audio quality on headphones or speakers without purchasing external hardware. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit subscription logic because users report revoked lifetime access → restore user trust and reduce refund surge. ### Outlook: Declining The audio-utility market is consolidating around stable, ad-light experiences, leaving this app exposed to churn.
