Great for when in a pinch, but you'd do yourself a massive favour by getting yourself a physical tuner. The app does what it can with the hardware of your device and does a good job when isolated with no background noise, but if anything else makes a sound it doesn't do so well. Not that the app is to blame so much as its just a limitation of using your phone to tune your instrument. The accuracy of the tuning won't be perfect, but when in need, this app can get you through a performance or two.

Generally a great app, and I would like to support the devs with Premium, however I feel €10 is overpriced. I would consider paying between €2-€4. And I believe you would receive many more purchases resulting in higher profit, if you lowered the price or introduced "pay-what-you-want".

With the latest changes relating to the GDPR this app is absolutely unusable unless you "consent" to their ad scheme. They lie to make you think that you have to give them permission to show any ads, but the setting is about personalized ads. The paid version is too expensive. Disgusting business practice. Uninstalled.

This is my go-to app for tuning my guitars, bass, banjo and anything else in need of a little audible tlc. It's easy to use, looks sharp (as opposed to flat) and for the years I've been using it, I've never had a single issue with it. How many apps can you say THAT about?!?

i've been using this tuner for as long as i can remember and have never had a single issue, never been bombarded with ads to the point it's unusable, and most importantly, never been gaslit into leaving a review like some other apps do every single time you open them. gstrings has always been there when i needed a reliable tuner. finally today it asked after all these years, even acknowledging i've been using it for a while. 10000 out of 10, have definitely already recommended to others.

I am self taught and this tool has been a trusted teacher in conditioning my ears to the frequency I'm seeking. if there could be one improvement, it would be that when it gets closr to the target I am seeking it would be more sensitive to the actual wave pattern as it could track ososcillatiins on a finer scale to better hit the desired target. as a tool for a self taught guitar player this is beyond value in what it has allowed me to achieve.

I have had many years. My favorite tuner Simple straightforward interface and works with many stringed instruments. Does not bounce around much like other tuners. You must use in a quiet environment. Small inobstrusive ads show on screen. Can specify instruments, but no mandolin; I say violin which uses same tuning.

Worked fine for a long time but now the free version is so unresponsive as to be completely useless. It seems to use so much CPU power figuring out which ad to display, that it has no time left to actually listen to the note and move the needle. You turn a tuning peg, or move to the next string and the needle does nothing, then after about 20 seconds it suddenly jumps. So, as I said, useless.
