Is "invoice app" a good niche?
No — "invoice app" is a saturated market. The top app (Invoice & Estimate Maker Pro) holds 5.0⭐ and users are largely satisfied. Breaking in requires a genuine 10x differentiator, not just a clone.
The "invoice app" market on the iOS App Store has an estimated 731K users across 17 apps in the Business category. With 731K estimated users, demand is clearly validated — the question is execution, not market size.
Saturated doesn't mean impossible. Notion beat Evernote. Linear beat Jira. Superhuman charges $30/mo in a world with free Gmail. But they all won with a radically better experience for a specific user — not by building the same thing cheaper. Only enter if you have a genuine 10x angle.
