## Review summary

Reviewers praise the app for accuracy, ease of use, and free, multi-instrument tuning. It’s reported to work across guitars, violins, ukuleles, kalimbas, lyres, and more, even catching drums and voices and performing well in noisy rooms. The range of tunings and instruments is a strong selling point. However, users repeatedly complain about intrusive upsell prompts and ads, frequent crashes or the app failing to open, and a lack of built-in support or tutorials. Overall, the app is valued for versatility and price, but reliability and support problems hurt the experience for many users.
