I paid for ad free because I want to help support this app and the developer.
However, I feel it's going to be very hard for me to convince others to use Sync. I am a long time user and so I have loyalty and I understand the benefit and so the money is worth it to me. It's also a nice way for me to give back after a decade of Sync for Reddit.
But I'm not sure I can convince newer folks with this price point.
That said, the app is great and I love it. Keep it up!
