Reflexa vs ArcadeOS

Reaction time test and reflex trainer: measure your reaction speed in milliseconds, compare it with the ~273 ms public median, and train to get faster. Free to start. How fast are you, really? Reflexa gives you the number in five seconds — and a plan to beat it. ▸ TAKE THE REACTION TIME TEST The classic green-flash test, done right on your phone. Wait for green, tap. Your result appears instantly in milliseconds with your tier — Lightning, Nice Reflex, Average or Room to Grow — and where you land against the median of millions of public reaction tests. Timing runs on your device, so there is no mouse or browser latency inflating your score. ▸ WHAT IS A GOOD REACTION TIME? • Under 200 ms — lightning: the range of competitive gamers and athletes • 200–250 ms — a genuinely fast reflex • ~273 ms — the public median most people land around • 300 ms and above — plenty of headroom, and the fastest gains Reaction time peaks in your twenties and slows with age, fatigue and lack of sleep. It also improves with practice. ▸ 60 REFLEX CHALLENGES, 15 MECHANICS Reaction speed is not one skill. Reflexa trains every kind: • Classic — pure visual reaction time • Phantom — the target vanishes, trust your instinct • Stroop test — your eyes say one thing, the word another • Peripheral — catch what appears at the edge of your vision • Pursuit, Catch, Echo, Glimpse, Heartbeat, Eclipse, Lightning, Crossfire, Duet, Trace, Pendulum Each mechanic has four difficulty tiers: Easy, Normal, Hard, Expert. ▸ ELO RANKING, LIKE CHESS A real skill rating that moves with every run. Six ranks: Bronze, Silver, Gold, Platinum, Diamond, Legend. Beat your level and gain points, slip and lose them — every tap means something. ▸ DAILY CHALLENGE & WEEKLY TOURNAMENT • A fresh daily challenge with streak and points • Weekly tournament for the top-score race • Game Center leaderboards: your country and the world ▸ SMART TRAINING & PROGRESS • Personal next target: −X ms to your next tier • Sequence mode: 5-round sessions for consistency • Full history, ELO trends and session analytics • AI Coach: personalized insights on Apple Intelligence devices, generated on your iPhone • Share cards to post your rank and best time ▸ APPLE WATCH • Train from your wrist, no phone needed • Live heart rate during the round • Three Watch-optimized challenges, synced with iPhone ▸ WHO IS REFLEXA FOR? • Gamers who want faster hand-eye coordination for FPS, fighting and rhythm games • Athletes and drivers who need to react first when it matters • Anyone who wants to stay mentally sharp with a daily brain game • Anyone curious about their own reflex test score ▸ FREQUENTLY ASKED Can reaction time be trained? Yes. Short, consistent practice measurably shortens it; Reflexa keeps your baseline and every session so the gain is visible, not imagined. Is a phone test accurate? Reflexa measures on-device with the same method every time, so your results are consistent and comparable day after day. Is it free? The reaction test, Easy challenges, the daily run and your history are free. Pro unlocks the rest. Free to download.

Welcome to ArcadeOS — a whole arcade in your pocket, and now on your wrist. 68 hand-picked original games, each one its own cartridge: full 3D open worlds, kart racers, ninja action, gothic pinball, paper-craft RPGs, sky shooters, momentum platformers, run-and-gun, belt brawlers, puzzle boxes and rhythm. Every game is an original creation in the spirit of the golden age of consoles — drawn in code, scored with real chip audio, and built to be picked up in seconds. HALLOW EDITION Worlds, not cartridges. LOOSE KEYS: HALLOW HOLLOW is a full 3D open city under an orange moon: take any car, hearse, helicopter, plane or boat, outrun a three-star heat system, fly a fast jet off a military airfield, land an airliner at the international airport, and work a phone full of jobs — in a city full of witches, skeletons, horsemen and the odd creature from an 1818 novel. At its heart is HOLLOWMERE, a haunted theme park with a graveyard coaster you can actually ride, a drop tower, and a lagoon parade with fireworks on the hour. MODS ship with it: god mode, every weapon, flight, moon gravity. IRONBARK is a heavyweight momentum platformer: an armored-bark brawler and a glider partner tag-teaming through an industrial jungle of barrel-cannon chains, mine-cart runs and hidden bonus rooms, drawn in fine-pixel art. GLIMMERGLASS KEEP rounds it out — a free-roam 3D collect-a-thon built over 25 nights of iteration. All three have original soundtracks synthesized live inside the app. CHERRY EDITION 23 games rated five stars by our testers before they shipped — look for the cherry on the cartridge. Highlights: Reefjack's lantern-tide run-and-gun, Thornhollow's gorge platforming, Quiet Falls' suburban-oddball RPG, Emberline's three-winter family saga, Cascabel's commedia brawler, Ironvane's vertical shooter, and Crestline GP's speedboat regatta. APPLE WATCH ArcadeOS ships with an Apple Watch app. Six games are built for the wrist and the Digital Crown: Redline Ridge (crown hops lanes, hold to burn), Sunstrip (crown steers, tap to shift), Ironvane (crown flies, hold to charge, tap to call your wingman), Truck Simulator (roll the crown and the truck drives itself — steer, hold to brake, deliver the cargo), Haywire (a horse loose in a farmyard full of physics: buck, jump, cause chaos) and Cairnglass (a crown-controlled falling-sigil puzzler). Runs on its own — no iPhone needed nearby. FEATURES 68 games — every one with its own hand-crafted cartridge art Home screen: your games as icons, with folders you make yourself Gold-star collection: beat a game, earn its golden seal.
