Picking a good ukulele tuner app is easy, but there's one detail that doesn't matter on guitar: the app has to be chromatic or have a ukulele mode. GCEA uses a high, reentrant G, and the baritone tunes to DGBE — notes that an app locked to a guitar preset struggles to recognize. With that out of the way, there are plenty of excellent free options.
In short: if you want to tune right now, without downloading anything or creating an account, EasyGuitarTuner works from your browser and supports ukulele too; if you'd rather have a native app with a dedicated ukulele mode, GuitarTuna and Fender Tune are the most popular picks.
What makes a good ukulele tuner app
Before you choose, look for these concrete features:
- Chromatic or with a ukulele mode: this is what matters most. It has to read GCEA (including the high reentrant G) and, if you need it, baritone DGBE. A fixed guitar preset won't cut it.
- Accuracy: it shows you steadily whether you're flat or sharp. A good app locks onto the note without "dancing" around — precious on the ukulele's high strings.
- Free with no sign-up: the best basic options don't ask for an account or payment.
- Multi-instrument: handy if you also tune guitar or bass with the same app.
- Ease of use: clear display, readable target note, no complicated menus.
- Native or browser-based: an installable app often has more extra features; a web tuner works instantly, with nothing to download and no space taken up on your phone.

The best ukulele tuner apps
The most convenient starting point is always software: you already have your smartphone or computer within reach, and the built-in microphone is more than enough. Here are the best ones compared, with an eye on which handle the ukulele well:
| App | Rating | Free | Notes |
|---|---|---|---|
| GuitarTuna | 5.0 | ❌ | Dedicated ukulele mode, automatic and chromatic. Freemium: ads and a PRO version. |
| EasyGuitarTuner | 4.5 | ✅ | Runs in the browser, nothing to install: supports ukulele plus 6- and 12-string guitar, no account. |
| Fender Tune | 4.3 | ❌ | Ukulele mode for every size, simple and clean. Tied to the Fender ecosystem. |
| TonalEnergy Tuner | 4.2 | ❌ | Chromatic and suited to any instrument, packed with features. Paid app. |
| Pano Tuner | 4.0 | ❌ | Fast, lightweight chromatic tuner that works fine for ukulele too. Full version is paid. |
✅ = 100% free, with no account, ads, or paid features. ❌ = freemium or paid (limited free version, with ads or in-app purchases).
Of the bunch, EasyGuitarTuner is the only one that's completely free: it works right in your browser, uses your microphone, and tunes the ukulele as well as 6- and 12-string guitar — no installation, no sign-up, from a computer, smartphone, or tablet. Since it's microphone-based, it works best somewhere that isn't too noisy. If that's how you like to work, also check out the dedicated guide to the free online tuner in your browser.
Ukulele mode or chromatic tuner: two valid paths
To tune a ukulele with an app you have two options, both perfectly fine:
- An app with a ukulele mode, which already has the GCEA notes set up (or DGBE for baritone) and often recognizes which string you're playing on its own. It's the most convenient route if you only play ukulele.
- A chromatic app, which detects any note at any pitch. It won't guide you string by string, but it's the most flexible: the same app tunes ukulele, guitar, and bass without changing a single setting.
If you tune a guitar too, many of the same apps cover both instruments: take a look at the best guitar tuner apps — most of them work in chromatic mode on the ukulele's four strings as well.
Which app to pick for your situation
To sum up, start from how you actually play:
- You want to tune right now, with nothing to install: EasyGuitarTuner in your browser supports ukulele, it's free, and it doesn't ask for an account.
- You only play ukulele and want maximum convenience: GuitarTuna or Fender Tune have a dedicated ukulele mode that guides you string by string.
- You also tune guitar or bass: pick a chromatic, multi-instrument app so you can switch instruments without switching apps.
- You have a baritone ukulele: make sure the app is chromatic, then tune to DGBE like the guitar's four highest strings.
In practice, most ukulele players keep an app or a web tuner within reach at all times: it's the fastest way to get the four strings in tune in a few seconds before every session. Start with whichever one convinces you most from this comparison — switching later is just a download away.
