How Much Does It Cost to Build an App?

Custom mobile app development is expensive mostly because of labor: designers, iOS engineers, Android engineers and project managers, billing by the hour over a project that typically runs three to nine months. Agency quotes for a business app with booking and payments commonly start around $20,000 and climb from there.

Ongoing costs add up too — hosting, bug fixes, app store updates, and redesigns as your business changes. A one-time build isn't really one-time.

AI app builders change the cost structure by removing the labor-hours component almost entirely. MzansiMobile plans start at $29 a month for a single app — a cost small businesses can justify without a funding round or a business loan.

The trade-off is scope: an AI app builder is built around the patterns of common business types — bookings, orders, memberships — rather than fully bespoke functionality. For most small businesses, that's not a limitation; it's exactly what they need.
