User Reviews

Users praise Reaction Time for its simplicity, accuracy, and ad-free experience, enjoying its clean interface and straightforward function of measuring reaction time averages. However, common criticisms include the unnatural press-on-release mechanic, distracting background clutter, and lengthy or inconsistent wait times. Many express a desire for additional test types such as tapping or auditory reactions, as well as social features like leaderboards or result comparisons. Overall, the app meets basic expectations but could improve in usability and expand its features to enhance engagement.

Pros

Simple and straightforward to use
No ads, providing an uninterrupted experience
Accurate timing and responsive, even on slower phones
Clean and intuitive interface
Provides average reaction time over multiple trials

Cons

The long and random wait times between signals can be frustrating
Requires pressing on release rather than press to respond, which feels unnatural
Background with too many writings and lines distracts users and affects focus
Lacks variety in reaction time tests (e.g., tapping, auditory stimulus)
No social or competitive features like leaderboards or result comparisons

Does exactly that. Tells reaction time. if you want an accurate way the most simple way possible... this is your app. Devs.. in future update make a second method that is audible and beeps.
