The Stamina Trainer removes all time constraints from click speed testing. Unlike timed tests (5s, 10s, 30s), this mode lets you click for as long as you want — whether that's 10 seconds or 10 minutes. It's the ultimate way to measure your true clicking endurance, consistency, and technique under sustained physical effort.
The live graph plots your CPS at one-second intervals, creating a visual timeline of your clicking session. Spot fatigue patterns: most people see CPS drop after 15–30 seconds. The graph shows your peak CPS, average CPS, and a stability score that measures consistency. A stability score of 90%+ means your speed barely fluctuates — a sign of excellent technique.
Perfect for gamers who need sustained clicking in Minecraft PvP, Cookie Clicker, or competitive FPS titles. Compare clicking techniques — jitter, butterfly, or drag clicking — and watch the graph to see which gives the most stable CPS over longer durations. Works on desktop, laptop, and supports mouse, touchpad, and touchscreen inputs.
Warm up your hand before long sessions to prevent cramping. Keep your wrist relaxed and use finger movements rather than whole-hand tension. Butterfly clicking often produces the highest sustained CPS. Watch the graph: if you see a sharp decline after 20 seconds, take short breaks and try again. Over time, your endurance will improve naturally.
After extended clicking sessions, some mouse switches exhibit mechanical drift — a gradual change in actuation force. This isn't a defect; it's the switch warming up. Our graph helps distinguish genuine fatigue from hardware drift: if your CPS drops uniformly over time, it's fatigue. If it fluctuates irregularly, check your switch condition.
