Guitar Tuner & Tone Generator

Trying to find an app that'll show me the Hz of the detected tone on screen. That's it. I'll work the tuning out from there. Actually, I'm trying to tune belt tension in a machine using the frequency of the strum. But the manufacturer doesn't recommend a specific app :( This app just sits there saying 440Hz all the time, and nothing on the screen changes when strumming the belt. No indication that anything is wrong. No suggestion on how to improve to get a reading. No idea what the app wants me to do to make it do its job.

I was looking for a tuner that could tell you what pitch your string was at but it gave me a tuner that told you if you were getting the cords right. It was however one of the best free guitar tuner apps I could find for my Apple Watch. At first my guitar instructor told me it would be exactly what we were looking for after he looked at the ratings and what it was about a little, but even after he saw the app he said it wasn’t really a good fit for what we wanted. This app would be great for people who are looking for a tuner that tells you if your playing the cord right but it was just more than what I was looking for. I feel like this would be a great app if you not only put the tuning for the cord but if you also put the tuning for the strings. Im really sorry for making this super long I just wanted to state my concerns my issues and the positive sides of the app. I also know that some of the longest reviews can get to the top. Anyway thanks for reading this and I hope some of you guys find what your looking for in this app.

I’m looking for a way to read the pitch of stringed instruments for the purpose of tuning and repair. This app is the closest I’ve found, but unfortunately doesn’t pinpoint the value. It gets to within 15% and the reading makes quantum leaps as you tune up and down which are not tight enough for my purposes. For regular tuning (for players) it’s fine.
