These Apps Were Built by Just One Person

IndieRank · March 30, 2026

You use apps every day without thinking about who made them. Most people assume popular apps are built by large teams. But some of the highest-rated apps on the App Store — with tens of thousands of reviews — were built entirely by a single indie developer. Here are the most remarkable examples from our database of 4,000+ indie developers.
