Simple, but awesome 😎

I use this everyday to tune my violin before violin class! It’s simple and easy to use, but definitely worth getting! I recommend this to any beginner violinist or anyone who simply wants to tune their instrument. Plus, it’s free to install, so you don’t need to spend money. I have tried various tools in the past, but this is the simplest and most accurate that I could find without it costing money. Oh and for anyone actually reading his, PRACTICE MAKES PERFECTION! so practice right now 🎻

Cheap Alternative for a Snark

About all of my classmates have bought a clip-on tuner that costed $20-35, and I’m one of the only ones who chose to download a tuner :0 My parents don’t have the time to buy a tuner but I have the time to download an app! Anyways this is great, completely functional, free, and I can also tune my friend’s viola. This is a great alternative, and I would definitely recommend it!

Super Easy to use

This was by far the easiest of several tuners that I tried. It tells you which string to pluck and gives you the pitch to listen for and finally measures the pitch of the instrument on a gradual scale so that you can see exactly where you’re at. Tuning is almost like a video game as you dial in the pitch to the target zone.
