GuitarTuna: Tune & Play Guitar

Review by eFreeware

If you own a stringed instrument and no separate tuner, GuitarTuna is probably the first app you would think to install. Yousician Ltd. has built it around a microphone-based tuner, then layered on chords, tabs and practice tools so the same app can follow you from tuning up to working on a song. With more than 100 million installs and a 4.5 average across roughly 2.67 million ratings, it is one of the most widely used music utilities on Android, and it costs nothing to download.

The appeal for a beginner is that everything lives in one place: you tune, you look up chords, you follow a trainer. The appeal for a more experienced player is narrower but real, particularly the tuning accuracy and the range of instruments and alternate tunings supported. I would expect most people to keep it installed even if they only open it to check a string before practice.

It has been on the Play Store since August 2012, which in app terms makes it a veteran, and the developer still ships updates, the most recent in October 2026. That kind of longevity matters for an app you might come to rely on before every session.

Tuning by microphone, without cables

The core of the app is the tuner, and it works by listening through your device's built-in microphone rather than requiring a cable or clip-on accessory. You pluck a string, and the app shows in real time whether you are sharp, flat or in tune. That is the whole interaction, and it is the reason the app has such broad reach: there is nothing to plug in and nothing to configure before the first note.

The instrument list is longer than most people will ever need. Alongside the obvious acoustic and electric guitar, there are tuners for ukulele, four- and five-string bass, violin, viola, cello, fiddle, mandolin, four- and five-string banjo, balalaika and cavaquinho, among fifteen instrument tuners in total. Guitar support covers six-, seven- and twelve-string instruments, so players with an extended-range guitar are not left out.

Tunings go well past standard. There are more than a hundred, including drop tunings such as Drop-D, Drop-C and Drop-A, open and alternate tunings, half-step-down, and a chromatic mode that will tune to any note on the scale. Custom tuning is there for anything the presets miss. The developer describes the accuracy as professional and credits advanced sound recognition, a claim I would treat as marketing until you have tried it against a reference, but the breadth of what it covers is not in doubt.

One practical note comes straight from the developer: if you have never used a tuner before, watch a tutorial video before you start, because tightening the wrong peg can damage a string or an instrument. It is sensible advice, and the app points you toward it rather than leaving you to work it out.

Chords, tabs and song material

Beyond tuning, the app carries a catalog of chords and tabs for more than 20,000 popular songs by well-known artists, and the developer references a wider figure of over 870,000 songs for chord and tab material. You can filter what you see by skill level, so a beginner is not handed a finger-twisting arrangement on the first attempt, and the tabs and chords move at your pace rather than forcing a fixed tempo. If something you want is missing, you can request it, and new songs and tabs arrive weekly.

For someone learning, the more interesting part is the teaching layer. There are video tutorials and interactive trainers, along with personalized feedback on your playing, and you can assemble your own learning path instead of following a fixed course. Tips from experienced guitarists are mixed in as well. The intent is clearly to keep you inside one app from tuning through to playing a full song.

That combination is what separates it from a plain tuner. A dedicated tuning app stops when the strings are in pitch; here the same session can continue into chords, a trainer or a song you are working on, which is convenient if you would rather not juggle several apps before practice.

Practice tools for the rest of the session

The practice side is more substantial than the tuner alone would suggest. There is a metronome where you set the tempo and adjust the time signature, which is the sort of tool players reach for constantly once they start working on timing. A chord library provides diagrams and audio for the shapes you are learning, so you can hear what a chord should sound like rather than guessing.

Chord games take a different approach, turning the shapes that keep tripping you up into something you can drill repeatedly, with customizable options. An ear trainer works on recognizing chords by ear, which is a skill that tends to lag behind finger technique for most self-taught players. There is also a left-hand mode that flips the interface for left-handed players, a small thing that makes the app usable for a group often overlooked.

Taken together, these tools cover a lot of what a practice routine involves: keeping time, learning shapes, hearing intervals and repeating the parts that are hard. None of it is exotic, but having it in the same app as the tuner and the song catalog is what makes the package feel complete rather than scattered.

What it asks of you, and what it costs

GuitarTuna is free to download, and the standard guitar tuner is described as free to use. The app does contain ads and it does offer in-app purchases, so the free experience comes with both. I would go in expecting a free tier that works and a paid layer on top rather than assuming everything is open from the start.

On the hardware side, the requirements are modest. Tuning relies on your device's microphone, so you need a phone or tablet with a working mic and enough quiet to let it hear the strings. No cable, no clip-on tuner, no external interface. That is the main reason the app travels well: the instrument is the only thing you need to bring.

The other requirement is patience with yourself. The developer's warning about watching a tutorial before your first tuning session is worth taking seriously, and the learning features assume you will put in regular practice rather than expect instant results. The app gives you the material and the feedback; the repetition is still yours to do.

Getting the most from it in practice

The most useful habit I would suggest is to treat the tuner as the entry point to a session rather than a separate task. Tune first, then move straight into the chord library or a trainer while the instrument is already in your hands. The app is arranged so that this flow is natural, and it saves the friction of switching between tools.

For song work, use the skill-level filter honestly. Choosing an arrangement that matches where you actually are makes the pace-syncing tabs far more useful than picking something impressive and fighting it. The request feature is there for a reason: if a song you are learning is not in the catalog, asking for it is a reasonable move, and the developer adds new material weekly.

If timing is your weak point, the metronome and the chord games pair well: one builds steady rhythm, the other builds the shapes you need to play in time. The ear trainer is the one I would schedule separately, since recognizing chords by ear improves with short, frequent sessions rather than long ones. Left-handed players should switch to left-hand mode before anything else, so the diagrams and interface match how they hold the instrument.

A tuner that grows into a practice companion

GuitarTuna earns its install count by doing the simple thing well and then adding more than most people expect. The microphone tuner covers fifteen instruments and over a hundred tunings, the song catalog is large and refreshed weekly, and the practice tools give you something to do once the strings are in tune. The 4.5 average from such a large body of ratings suggests the approach has held up over the years.

The caveats are straightforward. It is free with ads and in-app purchases, so the experience is not uncluttered. Beginners should heed the advice to watch a tutorial before their first tuning attempt, and anyone expecting the app to teach them without practice will be disappointed.

I would recommend it to guitarists, bassists, ukulele players and anyone else with a stringed instrument who wants tuning, chords and practice material in one place. It suits self-taught players building a routine and beginners who need the basics covered without buying extra gear. If you already own a hardware tuner and only need pitch reference, the extra features are there whether or not you use them.
