Does your controller drift, miss presses, or behave differently from one game to the next? MilliLog shows you exactly what it is sending. Turn every controller input into visible, measurable data. Watch buttons, sticks, triggers, the D-pad, touchpad, and gyroscope in real time, then record a millisecond-accurate log when you need evidence you can inspect or share. DIAGNOSE CONTROLLER PROBLEMS • Spot stick drift and dead zones in the live stick view. • Catch missed, delayed, or unexpected inputs. • Check trigger travel, motion data, touchpad events, and battery level. • Monitor multiple controllers at the same time. TEST MORE THAN BUTTONS • Run continuous vibration at the intensity you choose. • Explore six haptic oscillator patterns: Fast, Medium, Slow, Step, Random, and Ramp. • Test DualSense adaptive triggers independently on L2 and R2 with Constant, Weapon, Vibration, and Slope effects. • Change the light-bar color on supported controllers. • Enable optional sound feedback to hear inputs as they happen. RECORD AND SHARE RESULTS Capture complete input logs with precise timestamps, then export them as CSV or JSON for troubleshooting, QA reports, spreadsheets, or your own analysis. PLAY REACT Put your reflexes to the test in a built-in reaction game for one to four local players. Sign in to Game Center to submit your best times and streaks to the leaderboards. MilliLog works with controllers supported by Apple's GameController framework, including DualSense, Xbox Wireless Controller, and many MFi-compatible gamepads. Made for developers, QA testers, repair technicians, hardware enthusiasts, and players who want answers before replacing a controller. Also available on Mac. One purchase covers iPhone, iPad, and Mac. No ads. No tracking. No subscriptions. No in-app purchases.
