I've been on the TestFlight for a bit and I'm a for-sure day one subscriber. I was an Apollo Ultra ifetime'r - Pro since 2017, and Ultra since 2019.
Although I know I'm going to get some shit for this, I think the pricing is a bit high for early adopters. To be clear, I'm going to do it anyway, but Lemmy is still unproven as the next big platform - there's still Kbin, Tildes, Lobsters, and more. I think I recall Apollo lifetime was $24.99, a platform that had a hundred million users. I don't know if I can sell my friends on $17.99 for a year, or $50 lifetime, just yet.
My thought would be to cut that for a month or two - early-bird the price to $1.99/mo, $12 for a year, or $29.99 lifetime. Build up a user base. Then once it's got that install base, move to the prices advertised, as a proven app.
And just to prove this isn't inspired by me being cheap, check my comment history, I've been trying to give /u/steve228uk money for awhile now! :)
Opeth is so good. I know a few people who love their music but struggle with the vocals, but damn are they talented.
