How we ranked these guitar tuners
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: chromatic tuner for ukulele
Match the mode to your ukulele
A dedicated ukulele mode saves time over chromatic mode alone, since the tuner listens for ukulele tuning instead of any note. The EX, the BOSS TU-02, the JUSTPRO, the WOGOD and the AARVI all offer a ukulele mode or pattern, so compare the rest of the specs. Check whether you also tune guitar, bass or violin, since several of these tuners cover those instruments too.
Decide between rechargeable and battery power
Only the EX runs on a built-in rechargeable battery with USB-C charging, so it suits players who want to skip buying cells. The BOSS TU-02 and the WOGOD run on CR2032 cells, while the JUSTPRO uses a CR2 cell and the AARVI uses a C battery. Check the battery type before you buy, since the cell type decides what you keep on hand. A tuner with auto power off, like the BOSS TU-02 and the WOGOD, conserves battery life between sessions.
Check the clip and the display before buying
A clip that rotates lets you read the screen from your playing position instead of twisting the tuner on the headstock. The EX rotates 135° front and back with a full 360° swivel, and the JUSTPRO, the WOGOD and the AARVI rotate 360° as well. Look for a color display if you tune in dim light: the EX and the BOSS TU-02 both offer a color display. The EX uses a silicone-padded clip and the JUSTPRO uses a small orange rubber pad inside its clip, and both protect the finish.
Frequently asked questions
Do clip-on tuners work for ukulele?
Yes. Each tuner here clips onto the headstock and offers a ukulele mode or pattern, so it tunes a ukulele without a cable. Clip the tuner on, select the ukulele mode and tune each string to the display.
What is chromatic mode on a guitar tuner?
Chromatic mode tunes any note, not just the standard notes of one instrument. It suits players who tune to alternate notes or use several instruments, since it reads every pitch the tuner detects.
How long does the BOSS TU-02 battery last?
The BOSS TU-02 runs up to 24 hours on a CR2032 lithium battery. Auto power off switches it off when not in use, which conserves battery life between sessions.
Can one tuner cover guitar and ukulele?
Yes. The EX, the BOSS TU-02, the JUSTPRO, the WOGOD and the AARVI each offer guitar and ukulele patterns, so one tuner covers both instruments. Check the modes before buying if you also tune bass or violin.
