PureTune

Tune your guitar, bass, ukulele or banjo in seconds. No popups, no clutter. Just open, tune and play.

I built PureTune out of frustration.

Every time I picked up an instrument and needed to tune, I'd open a tuner app and get hit with popups, upsells and full-screen ads before I could even play a note. I just wanted to tune up and start playing.

So I built the app I wanted to use and added support for the other instruments.

PureTune is simple. Open it, pick your instrument, tune, and play. That's it.

There's a small banner ad at the bottom to keep the app free. After the first login there are no full-screen popups, no interruptions, no upsells in your face.

I'm a solo developer and I genuinely care about this app. If you spot a bug, want a tuning added, or have an idea to make it better, please drop me an email and I'll sort it.
