With a 4.45/5 rating from 6.5K reviews, it delivers strong user satisfaction.

<!-- speakable-start -->
> **Bottom Line:** Restoring the manual panning controls would immediately resolve the primary churn driver for the binaural beat segment, which currently views the latest update as a regression.
<!-- speakable-end -->

**Best for:** Musicians, audio engineers, and individuals seeking sound therapy tools like tinnitus masking or relaxation noise.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [PIVOT] Restore manual panning controls because their removal broke binaural beat use cases → improve retention among sound therapy users
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Mixed

The utility audio market is consolidating around tools that offer high-precision control, and Frequency Sound Wave Generator is currently positioned as a high-capability option. However, the recent regression in panning functionality and purchase restoration issues threaten to erode the trust of its core technical audience, which is essential for long-term retention.

- 🟢 The latest release added background audio playback, which enables the app to serve as a persistent sound source for productivity and relaxation.
- 🔴 The removal of manual panning controls in the latest update creates a functional regression that directly impacts the binaural beat user segment.
