@christianselig Ugh this is the worst news. This app was the single biggest thing that pulled me back to iOS from Android. I'm so sorry it's gone this way. Thank you for this.
I posted this to twitter, but echoing it here:
How can I make sure I don't get a refund? You owe me nothing. You provided a service that was worth far more than its cost to me for years. Thank you for building and growing this. I'll watch to see what you do next and how I can support it.
