"body": "So I was looking for an app for tuning my guitar that didn't collect my data. I've used the app for a bit and it seems like it has an inaccurate pitch detection. I've tested it out compared to my regular tuner and this tuner seems completely off. Also theres no option to edit or remove custom tunings. So when you want to get any of them off, you have to delete and redownload the app😐️. But other than that, the actual app seems nice, like for the UI. It's just a shame that I can't use this tuning app to tune my guitar.",
