About this app

Lightweight application with a highly efficient detection algorithm. Less memory and CPU usage, which
makes battery life longer, Even on devices with weak CPU response still very smooth and fast, that allows for the tuning process to be precise and quick. This is not like a slideshow with a long delay, as in many other guitar tuner applications.

Minimalist and informative design does not distract, making the tuning process easy and comfortable.

Ratings and reviews

Universal Tuna is the coolest tuna in the ocean. Wait, what's that? It's not a fish? Aw, man... Anyway, this app rules. No ads or cash-grabs, n it's always been decently accurate for any sounds I've needed to use it on. Even features a keyboard you can play which is pretty useful as a reference for vocals. Only issue is sometimes it has trouble displaying specifically the A string on the bar thingy for guitar, but you can still just look at what the text says. Highly recommend.

It works great, and my ear says the accuracy is...pretty well spot on. I think it is a good tuner -(one of the best out there, in my opinion...)- I (usually) always go back for at least one more pass and fine tune it by ear although sometimes it is not even necessary after tuning up with Universal Tuner. Great app! This is one of my Top 3 Best Tuner App selections...

I finally got fed up with Gstrings' tendency to not hear my violin's E string and decided to go on the hunt for a new tuner app. Imagine my delight when I came across one that was rated 4.8 stars! Any app able to coax an average 4.8 from an audience as picky as musicians can be I had to check out. Great app! Does exactly what it advertises. A little tricky to know that you have to use the back button once to save your instrument, but a small price to pay such an excellent tuner.
