Between $38 and $135 per hour on vetted marketplaces depending on seniority and platform, $115 to $210 through an agency, or $100,000 to $175,000 base salary full-time.
Cross-platform usually wins on cost when you need both stores, since one team covers both. Native wins on polish and hardware access, which can matter more than the savings for consumer apps.
It scales with scope: a focused single-purpose app is typically hundreds of hours; a marketplace or social product runs far beyond that. Multiply expected hours by the seniority band that fits your risk.
One strong senior can carry an MVP on a single platform or in Flutter or React Native. Plan for a second engineer once release cadence, QA, and store operations start competing for the same person's time.
