Dan Counsell, with a revenue snapshot of an ordinary day for his company, Realmac:

"There's been a fair amount of talk lately about whether it's still sustainable to be an indie developer. The short answer is yes, but that doesn't mean it's easy. I think most developers will agree it's now harder than ever to make a living on the App Store.

"The peak for indies on the App Store was around 2013. It was much easier back then to launch a financially successful app. Things have changed. The larger, more established companies now take the lions share of revenue. This is particularly true for games on the iOS App Store, less so on the Mac. However, we need to face the facts that this is what happens when a market matures, the bigger companies take over and make it harder for the little guys to get a foothold in the market."
