Ask HN: Indie app developers how do you monetize your apps?

I’m about to submit a small app to the iOS App Store. It’s mostly just a hobby at this point and I’m not looking to get rich off it. However I would like to recoup the $99 annual fee and maybe earn a little fun money.

What monetization strategy have you had the most success with? Freemium, up front price, ad-supported? I think subscription fatigue is real so I don’t plan to go that route.
