<!-- speakable-start -->
> **Bottom Line:** Cello Tuner's multitasking integration provides a clear utility advantage, but the six-year development gap creates a critical risk of obsolescence that will eventually force users to migrate to active competitors.
<!-- speakable-end -->

**Best for:** Cello players seeking a dedicated, simple tuning tool for their instrument.

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

- [ ] [MAINTAIN] Audit codebase for iOS compatibility because the app has not been updated in 76 months → prevent sudden churn from OS-level breaking changes.
<!-- /section:pm-actions -->

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

The instrument-utility market is shifting toward apps with consistent update cadences and multi-instrument support. Cello Tuner's lack of activity leaves it exposed to platform-level changes, which will likely accelerate user churn to more reliable alternatives.

- 🔴 The six-year development gap signals a maintenance-mode status, which erodes user trust and increases the risk of abandonment during future OS updates.
