This handy A440 Tuner by Ownly is a just what I needed! The accuracy is spot on I don’t need to worry that I forgot my tuner or that the battery went dead on a gig or in the studio. I also like that it’s a one time nominal payment to own it. I’ve had a lot of tuners over the past thirty plus years that I’ve either broken or lost. This app is great because it’s a simple design, very easy to use, and accessible via phone or computer. Well done Ownly!

Clean, accurate tuner that locks quickly. Points for the simple interface and one-time purchase.

Very accurate tuner with a clean, readable display. Works great for guitar and bass. Refreshing to see an app that prioritizes usability over gimmicks.
