I found the Tuner T1 Pro incredibly intuitive and much simpler to use than other tuners I’ve tried. Fine-tuning each string was surprisingly easy—just a matter of watching the meter on the app. I highly recommend this program for beginners. I gave it five stars because, beyond its effectiveness, it helped me save money on piano tuning. At first, the idea of tackling this task was a bit intimidating, but it turned out to be much smoother than I expected. Fine-tuning each string became almost enjoyable, thanks to the clear indicators on the app. I definitely suggest this program to anyone just starting out.
Many of us (orchestral musicians and soloists) use Tuner T1 Pro because there is a lime green screen that appears when your pitch is perfect or nearly so.

Even that tolerance can be adjusted for the most accurate of intonations. All of my students now use this, partly because they have Apple products, but also because it is a pleasure to use!
This app has served me well throughout my orchestral and musical career!!! I love it so much and I am exceedingly proud to call it my favorite tuning app of all time, but there is a strange bug, glitch, or whatever that happens pretty infrequently but is highly inconvenient as it persists for a long time as it engenders itself. At random the app will stop registering sound and act as if my microphone isn't on, no matter if the setting in the settings is on or off. The only solution I'VE personally found is turning off my sound identification, but after doing so the app is noticeably worse quality and has a wildly more erratic pick up rate. I wonder if it's my phone's microphone automatically "reducing" background noise or something else... Please look into this, I would really regret to need to resort to a highly expensive real tuner.
Tuner T1 Pro is the ultimate instrument tuner, designed for precision tuning of a wide range of musical instruments. Whether you're tuning a guitar, v...
