When tuning a guitar the strings each need to vibrate at the right frequency.
The string's length and tension defines the rate of vibration. The tighter a string is, the faster the rate of vibration, resulting in higher pitch.
To tune your guitar here you should be in a quiet location with your volume turned up.
Make the room as quiet as possible, what you're listening for is subtle.
If you're tuning an electric guitar plug it in, turn your amp to a clean sound,(no effects turned on), and not too loud.

The guitar goes out of tune faster if you tune down to the note.
Aim to have the string and tuner sound identical.

Start by plucking your low E string and clicking the string on the free guitar tuner.
Listen for a wavy sound between the tones. As you turn the tuning peg the waves will either get slower or faster. Turn the peg in the direction that makes the wave slower until there is no wavy sound at all. If the waves start getting faster turn the peg in the other direction.
Repeat with each string, after all six strings double check.
Take your time!
It's going to feel awkward at first, but the more often you tune your guitar, the easier it becomes.
If you're guitar is tuned correctly it should have a nice sound when you strum all six strings. If the guitar sounds raspy, or it sort of barks, try again. Be patient you'll catch on.
