Is "Anonymous chat" a good niche?

Risky — "Anonymous chat" is a crowded market. Apps average 3.8⭐ with a Zombie Score of 33/100. There's some user dissatisfaction, but enough decent options exist that you'd need a clear differentiator to break through.

The "Anonymous chat" market on the iOS App Store has an estimated 1.7M users across 18 apps in the Social Networking category. With 1.7M estimated users, demand is clearly validated — the question is execution, not market size.

Overcrowded doesn't mean impossible — but it means the generic approach won't work. Target a specific underserved sub-audience rather than competing on features. A niche-within-a-niche often beats a head-on fight with established apps.
