01 / START HEREKnow your notes.
Know your notes.
Hear the difference.
Acoustic guitar tuning benefits from a clear readout, especially when moving between open chords and fingerstyle arrangements. Standard tuning is E–A–D–G–B–E, but many acoustic players also explore dropped and lowered tunings.
Why this matters.
The Basic edition emphasizes straightforward tuning; Acoustic Guitar Tuner Pro lists seven tuning options, including Standard, Half Step Down, Full Step Down and several drop tunings. Compare them below and confirm current device requirements on the App Store.
Practice note: Tune up to the desired pitch rather than repeatedly overshooting it. Check chord intonation after the open strings are in tune.
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 acoustic 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
Tune up to the desired pitch rather than repeatedly overshooting it. Check chord intonation after the open strings are in tune. Play a familiar passage or chord afterward to confirm the result by ear.

Questions musicians ask.
Can I use a acoustic 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. Tune up to the desired pitch rather than repeatedly overshooting it. Check chord intonation after the open strings are in tune.
