Know your notes.
Hear the difference.

Guitarists switch between standard tuning, half-step-down setups and alternate tunings for different pieces. Whether you play steel-string acoustic, electric or nylon-string classical guitar, a focused tuner helps you start with confidence.

QUICK REFERENCE

For a standard six-string guitar. Alternate tunings use different targets.

THE MUSICAL CONTEXT

Why this matters.

Browse acoustic, electric and classical guitar tuners independently. Selected Pro editions include seven tuning choices, with common alternatives such as Drop D, Drop C and Drop B. Features vary by edition; the individual app pages document each app rather than merging the claims.

Practice note: After changing a string substantially, retune neighboring strings. Alternate tunings may also require attention to string gauge and tension.

02 / PRACTICAL WALKTHROUGH

A better way
to get in tune.

Follow these steps using the app and your instrument. They are general guidance, not a claim that every interface has identical buttons.

01

Check the instrument and tuning

Identify the exact instrument and string count. For alternate tunings, confirm the target notes before changing string tension.

02

Open the matching tuner

Launch your guitar tuner on iPhone or iPad. If prompted, allow microphone access and select the relevant available preset.

03

Play one open string

Pluck one open string cleanly, then wait briefly for the pitch reading to stabilize.

04

Adjust in small increments

Compare the detected note with your target. Make gradual peg or machine-head adjustments; avoid overtightening and stop if resistance feels abnormal.

05

Recheck the complete instrument

After changing a string substantially, retune neighboring strings. Alternate tunings may also require attention to string gauge and tension. Play a familiar passage or chord afterward to confirm the result by ear.

05 / TROUBLESHOOTING

When a note doesn't settle.

A few common situations and practical ways to address them.

?

Chords sound wrong although open strings match

Check finger pressure and intonation as well as the open-string targets.

?

Alternate tuning feels unstable

Large pitch changes affect total tension; retune neighboring strings and allow time to settle.

Questions musicians ask.

Can I use a guitar tuner on an iPhone or iPad?

Daikyouju Labs publishes dedicated music apps for iPhone and iPad. Compatibility, supported iOS/iPadOS versions and feature availability differ by app and may change; verify your device against the live App Store listing.

Which version should I choose: Basic or Pro?

Compare the actual presets and features of the versions listed below. A Pro edition may offer additional tuning options or tools, but always confirm its current App Store description and price before downloading.

How do I know which tuning is correct?

Start with the note sequence required by your instrument, arrangement or teacher. After changing a string substantially, retune neighboring strings. Alternate tunings may also require attention to string gauge and tension.
