No. But you have to pay for ad-free. The ultra subscription service is more expensive than it was under reddit Sync. I'm hoping the prices will go down as the app gets more popular. I'm guessing the dev is trying to make up for the lost revenue from shutting down the reddit app.
I use sync and love it. I used sync for reddit and paid the pro and the ultra subscription. I don't have a problem with the app. I was just clarifying what the payment options were for. I don't know how expensive it is to run an app or the server for the ultra features.
