User Reviews

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.

Pros

Easy to use and free/affordable
Accurate tuning across many instruments
Catches drums and voices; works in noisy environments
Supports a wide range of tunings and instruments
Great value with free access

Cons

Intrusive upsell prompts and ads that interrupt tuning and push for a subscription
Frequent crashes, freezes, and occasional inability to open the app
Limited or missing in-app support/instructions (no built-in help)

Recent reviews

It is very helpful to tune an instrument, but I wish it would tell us like which way to two fine tuners and if it needs to be fine, tuned or peg tuned
