Or if you’re paying, just spend the extra few books (it’s $10) and get Petersen Strobosoft which is the absolute gold standard.

Or skip the idea that your phone makes a good tuner, spend $35, and get the TC Electronic Unitune. It's by far the best tuner I've used so far, and it's small enough you can just throw it into your guitar case. (Or leave it permanently attached)

Plus, it's much less fiddly to handle than balancing a phone and a guitar :)

Ultimately, it's a matter of taste, and what you use them for.

Lots of things to tune that aren't electric guitars ;)

The TC works just fine w/ any number of string instruments that aren't guitars or electric :)

Now try to tune a woodwind with one :)
