F1 START-LIGHTS SIMULATOR

Experience the core game loop of RecordFlex directly in your browser. Complete with visual queues, sound triggers, and instant F1 timing.

Instructions: Press "TAP TO READY" to initialize the simulator. The F1 starting lights will illuminate red one-by-one. The moment all lights turn off completely, tap the screen as fast as you can. Avoid false starts!

ELITE TRAINING ARCHITECTURE

Built with zero latency targets, RecordFlex is engineered to help F1 enthusiasts, gamers, and athletes hone their timing to the absolute limit.

High-Precision Timing

Utilizes ultra low-latency touch listeners capturing metrics on down-actions. Calculated in native nanoseconds to deliver precision down to the millisecond.

16 Escalating Tiers

Progress through four structural disciplines including standard visual alerts, erratic pacing delays, blue light inhibitor distractions, and Programmatic Audio synth challenges.

Fake-out Distractions

Face surprise level triggers like F1 false starts, glitching panels, red background flashes, and unexpected screen prompts designed to separate the elite from the rookies.

16 CHAO-LEVEL DIARY

Discover the complete breakdown of the challenges you will face. Reach a reaction speed below 150ms to attain the legendary rank of "Alien".

01 No Limit

Novice

The perfect sandbox to get comfortable. Wait for 5 F1 starting lights, and tap the moment they turn off.

Consistent
5 Fixed Lights
02 ≤ 449ms

Rookie

Adds dynamic variance to the timing array. Be prepared for random light sequences between 3 and 7 bulbs.

Consistent
3..7 Variable
03 ≤ 349ms

Driver

Pacing becomes erratic. The delay between individual lighting steps deviates dynamically up to 150%.

Erratic
5 Fixed Lights
04 ≤ 279ms

Fast

Combines erratic start sequencing with variable light counts. The true gateway test into fast-paced timing.

Erratic
3..7 Variable
05 ≤ 239ms

Quick

Introducing fake-outs. Expect quick flash indicators, glitches, and fake-out starts. Keep absolute focus.

Consistent
5 Lights + Surprise
06 ≤ 209ms

Pro

Combines unpredictable light counts with heavy surprise triggers. False starts result in instant failures.

Consistent
Variable + Surprise
07 ≤ 184ms

Elite

Pushes requirements under 190ms. Erratic pacing sequence coupled with fake flashes will stress your focus.

Erratic
5 Lights + Surprise
08 ≤ 159ms

Legend

Pure cognitive chaos. Dynamic variable light counts, highly erratic delays, and unpredictable glitching frames.

Erratic
Variable + Surprise
09 ≤ 299ms

Thinker

Inhibitory reflex training. If the final timing alert flashes BLUE instead of Green, you must NOT tap!

Consistent
5 Lights + No-Go
10 ≤ 269ms

Careful

Variable bulbs matching the No-Go blue trigger pattern. Builds crucial cognitive inhibition skills.

Consistent
Variable + No-Go
11 ≤ 249ms

Steady

Blue-light No-Go testing coupled with unpredictable erratic bulb timing intervals. Restraint is key.

Erratic
5 Lights + No-Go
12 ≤ 229ms

Focused

The ultimate inhibitory challenge. Quick flashing distractions and No-Go patterns trigger simultaneously.

Erratic
Variable + No-Go
13 ≤ 239ms

Listener

Train your auditory timing. Watch no lights; listen to the pacing sound triggers and wait for the high beep.

Audio Mode
440Hz / 880Hz
14 ≤ 199ms

Sonar

Auditory beeps with variable sequencing parameters. Builds robust acoustic awareness.

Audio Mode
3..7 Variable
15 ≤ 169ms

Echo

Audio beeps delivered at highly erratic millisecond pacing. Requires deep mental focus.

Audio Mode
Erratic Pacing
16 ≤ 149ms

Blindfold

The ultimate audio reflex test. Erratic auditory sequences with sudden noise surprises and fake signals.
