I'm generally not a cheap ass when it comes to apps I use a lot, but it's kinda crazy compared to a full blown music production app like FL Studio Mobile that costs $15. If it were under $10 I doubt many would be complaining. Just my honest opinion.
FL studio will always make the most of their money through the desktop version. FL can afford to make a little less money on their mobile app especially considering that it's likely a gateway for a lot of people to purchase the full version. Sync is a bit different in that regard. There's also much less of a market for lemmy readers.
3rd-party Reddit app devs: "Reddit is so greedy! We're leaving! ... Hey guys, pay me $17 per year for a gateway to a free service that I have nothing to do with! ... Too high? Fine! Pay me $20 for the portal for the free service if you want it without ads!
Couldn't be more obvious you have no clue how much work app development and support are.
Everyone's free to use whatever they want. Not sure why it's necessary to shame a one-man dev team that spends countless personal hours to make an excellent product, for needing some income for doing so.
$17 for all the extra feature is not high imo. $20 for basic app is, it makes the subscription model much more appealing and i bet that's what he's going for.
