User reviews

Recommended

Won’t pretend that this is the first tuner I reach for, given that I invariably have a clip-on or pedal tuner to hand, or foot, but if you’re thinking of a strobe tuner this does the job brilliantly, and represents fantastic value compared to buying a dedicated unit. If you’re a guitarist at the stage of needing to do or even just tweak your setups, for example, then you can certainly use the extra accuracy and information you get. There’s something of a learning curve, but that’s going to be true for any strobe tuner.

It’s also worth noting that the developer is responsive and helpful. When I upgraded my phone recently the new screen size broke the app’s display, but once I reported that, it was sorted almost immediately.

Unreservedly recommended.

Scam

Big scam, taking money monthly, always crashes, won’t let me unsubscribe.

Worked well … not anymore

Then: Worked well. Tuned Guitars, Basses, Drums.
Now: Can’t open it anymore. App closes within a second.

Only crashes on iPhone

RIP-OFF for iPhone: Was hired to tune a piano, had to turn down the job because it no longer runs on my iPhone, bur you charged me $13.00 anyway.

Unusable in 2024

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 the app or retire it
