Split it four ways
| Skill | In game | Reflex Lab test |
|---|---|---|
| Simple reaction | Reacting the instant an enemy appears | Reaction Time, Auditory Reaction |
| Aiming | Moving accurately to a target and clicking | Aim Trainer |
| Inhibition | Not shooting teammates or decoys | Impulse Control (Go/No-Go) |
| Peripheral vision | Noticing movement at the screen edge | Peripheral Vision (permanent unlock with one ad) |
If your Reaction Time ranks high but Aim Trainer ranks low, the bottleneck is movement accuracy, not reaction.
Refresh rate and frames
| Monitor / screen | One frame |
|---|---|
| 60 Hz | 16.7 ms |
| 144 Hz | 6.9 ms |
| 240 Hz | 4.2 ms |
High refresh rates cut the time before you see things; they don’t make you react faster. Phone scores and a PC gaming setup have different delays, so don’t compare them directly.
Weakest area first
- For a week, play a few rounds of all four areas to set a baseline
- Play the weakest area’s test 3 times a day
- Maintain strong areas once or twice a week
- Keep difficulty fixed; when you hold steady in the top 15% (A or better), move to Hard

FAQ
Does phone Aim Trainer help my PC aim?
Finger taps and mouse movement are different motions, so it doesn’t transfer directly. Use it to understand your pattern, such as “quick to react, slow to aim”.
What does Aim Trainer measure?
After your first tap, the average time per target in ms. Misses cost no time but count against your accuracy.
