Most mobile apps provide some form of service, and disruption to this service is considered a worst-case scenario for both users and providers. Disruptions can have significant negative effects on the brand, resulting in lost revenue and lasting reputational damage. To mitigate these risks, measuring the Mean Time To Repair (MTTR) is crucial, as it measures the average time taken to resolve issues from detection to repair. A lower MTTR indicates a faster response to disruptions, which can help save money and goodwill. MTTR is an important metric for assessing app maintainability and is closely related to other reliability metrics such as Mean Time To Failure (MTTF) and Mean Time Between Failures (MTBF). Application performance monitoring tools like Instabug can help detect and diagnose network issues before they affect MTTR, providing a proactive approach to maintaining app performance. By tracking full round-trip network requests on the client-side, Instabug helps identify and act on issues faster, ultimately improving user experience and reducing costs.
