Mobile Application Performance Monitoring (APM) is critical due to rising user expectations for performance standards. Building in-house APM software may seem cost-effective, but it often comes with hidden functionality and opportunity costs, making commercial software a more profitable option. Estimating the development and maintenance costs of an in-house APM tool can be complex, requiring an inventory of necessary features and considering infrastructure needs, user interface design, research and development, maintenance, and opportunity costs. These costs often exceed the price of a commercial software subscription. Commercial APM software offers increased customer retention and ROI, reduced downtime, and eliminated in-house workload, making it a known expense with advantages over building in-house. Evaluating commercial APM software can provide a turnkey solution with customizable features to suit business needs.
