Key Performance Indicators to Watch¶

To test with purpose, you need to know what success looks like. Key performance metrics give you a clear picture of how your app behaves—and where it might be falling short.

At Abstracta, we recommend focusing on a few core signals:

• App startup time: Affects first impressions and user retention by shaping how quickly users can begin interacting with the app.
• Response time: Reflects how quickly the app reacts after a user action, making it a highly visible indicator of performance
• Resource usage: Helps monitor CPU, memory, and battery behavior to identify inefficiencies that may affect stability and usability.
• Throughput and error rates: Reveal backend/API reliability by showing how well services and endpoints handle requests under different levels of demand.
• Trends in performance data: Spot issues early and prioritize fixes by helping teams identify recurring patterns, detect regressions over time, and focus on the changes that matter most.
• Crash rate: Measures how often the app fails during usage, helping teams identify stability issues caused by unhandled exceptions, resource limits, or device-specific problems.
• Battery consumption: Shows how much power the app uses during operation, helping teams identify inefficient background activity, excessive network calls, or heavy processing that can affect usability.
• API latency: Measures the delay between sending a request and receiving a response from the server, which can directly affect user flows because many app interactions depend on APIs.

Tracking these consistently helps you identify performance bottlenecks before they reach production.
