Precision Strobe Tuner

Honestly, I don’t understand all the positive reviews. This tuner is borderline unusable, maybe it’s due to the updates stopping ages ago, maybe it’s due to the microphone being so much different on iPhone 15, but this tuner cannot be dialed in, no matter what noise filters are on. God forbid you have central air going in the next room, it won’t be able to differentiate its note vs that of the guitar sitting 6 inches away. Only time I’ve ever felt legitimately ripped off on the App Store. Update

Used it to verify that the unisons in the upper register on my Baldwin SF-10 piano were off after a recent tuning. Also determined the stretch was suboptimal for my piano. When I finally get a tuning with the stretch I find most pleasing, I will use it again to set one of the custom temperaments to the values I like so we will have it for next time!

I use this for my guitar and the kids use it for their violins. Now, I wouldn't use any thing else. Really nice.

From a student's perspective: I want something similar to "Cyber Tuner" in hand. This affordable app offers similar precision strobe display, which is valuable even just to train my hand technique. The temperament sounds quite fine; one could of course fine tune after the app. I like that the app is being updated often. It doesn't have presets for specific piano models, which shouldn't be a problem when a student is learning to tune by ear. I am very thankful for this app. It does use a lot batt

It saved my butt in the studio. Worth the money just for that.
