iOS makes it simple to distribute: put it on the store and you're done; both launches and updates.
Outside this ecosystem you have to take care of everything yourself and the biggest inconvenience I saw was offering updates to your users.
Welcome DevMate, a tool to distribute your software. Luckily, they have merged with Paddle, so that was a big plus: offer licensing and purchasing through Paddle, downloads and in-app updates through DevMate 💪🏻
The integration was super simple, as well.
