## Review summary

Users like Reaction Test Pro for its simplicity, quick 5-second tests, and addictive feel, with some praising the low ad load. However, multiple reviews flag timing issues: the app often delays or records the hit on finger lift, producing inaccurate reaction times. The UI is also cluttered, with several buttons and conflicting start/stop behavior. Feedback about performance can feel discouraging. Content is limited to a single core test with few other games. Visual feedback is weak (go light is subtle) and some want audio cues. Ads can interrupt testing, though not every user experiences them.

### Pros

- Easy to use / simple interface
- Fun and addictive
- Quick to run / lightweight (5-second tests)
- Minimal ads during testing
- Helps you stay sharp / practice reaction time

### Cons

- Delayed or inaccurate reaction time measurements and tap registration
- Cluttered UI with too many buttons and conflicting start/stop controls
- Ads can interrupt testing / annoying
- Limited game modes / few alternative tests
- Weak visual feedback go light is subtle and lack of audio cues
