What will your app actually cost?
Most agencies answer that with “it depends” and a discovery call. Pick what you need below and get an indicative range and timeline immediately — built on the same fixed prices we publish across the site.
Questions we get asked before every build
How much does it cost to build a mobile app?
Matrytech builds fixed-price iOS and Android apps from $7,500, shipping in about four weeks. Apps needing custom integrations, real-time features or AI typically run $10,000–$25,000. The calculator on this page gives an indicative range once you pick your features.
How much does an AI agent cost to build?
A single agent with tool use starts at $15,000. A multi-agent system with memory, orchestration and enterprise integrations runs $40,000–$80,000. Every build is quoted fixed-price per project — never hourly.
Is the estimate the price I pay?
The estimate is indicative. The fixed price is agreed after a short scoping call, and once agreed it is the price you pay — no hourly billing and no scope-creep invoices.
What drives the cost of an app the most?
Real-time features. Live video, streaming and chat are the biggest single drivers, because they add infrastructure as well as interface. After that: number of platforms, third-party integrations, and any compliance regime such as HIPAA or SOC 2.
What happens after launch?
Most clients move to a maintenance retainer of $1,500–$3,000 a month, covering bug fixes, OS-update tracking, security patches and dependency updates. It is optional and cancellable at any time.
