Guitar tuners aren't always the simplest gadgets in the world, even if they're mostly charged with an impossibly simple task. In fact, advanced features on more expensive tuners might confuse someone who doesn't know what they're doing. This one, though, opts for simple and cheap. There's something to be said for that.
This idea blows my mind: An electric guitar tuner that analyzes a full strum all at once, telling you which individual strings need tuning. Brilliant!
