It holds a 4.92/5 rating from 49 reviews.

<!-- speakable-start -->
> **Bottom Line:** Guitar Tuner provides a high-quality, free utility that retains core users through simplicity, but the lack of development cadence leaves the app vulnerable to better-supported competitors.
<!-- speakable-end -->

**Best for:** Ukulele players seeking a dedicated, real-time tuning tool on their mobile device.

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

- [ ] [MAINTAIN] Audit current codebase for iOS compatibility because the app has been dormant for 20 months → ensure baseline stability
<!-- /section:pm-actions -->

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

The ukulele tuning market remains stable, but the lack of active development for Guitar Tuner creates a long-term risk of technical obsolescence. Maintaining the current, ad-free experience will continue to satisfy existing users, but the app will likely lose ground to competitors that offer more frequent feature updates.

- ⚪ The 600-day update gap indicates a maintenance-only posture, which limits the ability to respond to new iOS interface changes.
- 🟢 High user satisfaction with the free model suggests the core utility is sufficient for the current audience, minimizing churn risk.
