I’ve been using Snipd for about a year and this app has been life changing. I listen to about 17 hours of podcasts a week and I want to take notes on 95% of them. Snipd makes it so easy to do. I can triple click my headphones and record a snip. The app also improves rapidly which is welcomed. It’s an easy subscription for me to pay.
