What's New in Nurunuru Checker
1.12.0
October 27, 2026
v1.12.0 ・Added a free 15-second screen check. You can share the result as an image. ・Added a Reaction Speed Test that compares how fast you react at the highest refresh rate and at 60Hz. ・The check result now shows your rank among devices of the same model (you can turn this off in Settings). ・Live Measurement (formerly the 120Hz Display Test) is now unlocked for 24 hours, like the other tests. ・When the display is limited to 60Hz (for example by Low Power Mode), the app now tells you why. ・While limited to 60Hz, jank is now counted against 60Hz (previously every frame was shown as jank). ・Choosing Rinka Mode now also switches the app icon to Rinka. ・If you close the ad before it ends, the app now explains why nothing was unlocked and how to unlock.
