How fast are your reflexes? Reflex Rush times every tap and gives you the number ā your average reaction in milliseconds, run after run, charted so you can see whether you are actually getting faster. Each round lasts 30 seconds. Targets appear and shrink; hit them to build a combo, hit them dead centre for a Perfect, and drive the multiplier up through Fever and Overdrive before the clock runs out. WHAT'S IN IT ⢠Four endless modes ā Standard, Sudden Death, Marathon and Bullseye ā unlocked as you level up ⢠A 20-level challenge ladder across four themed chapters, one to three stars per level ⢠A soundtrack that plays along with you ā every hit lands in key, the music builds with your combo ⢠Your reaction-time trend, charted: a best is a trophy, a trend is progress ⢠Daily challenge, a seven-day login ladder and a weekly event ⢠24 achievements and six ranks to climb ⢠24 target skins and 10 arena themes ⢠Game Center leaderboards for score, combo, perfects and fastest average reaction ⢠iCloud sync, so your records follow you to your other devices ⢠Challenge a friend ā send your score as a link and they play the same run Built for one hand and short sessions. Every sound and every particle is generated on the device: no account to create, no extra download, and the game itself plays offline. Free to play. Optional ads let you continue a run or double your coins; an occasional ad may show after a round. Skins, coin packs and the one-time Pro upgrade (which removes ads) are optional.

Reflex is a reaction trainer. Tap to arm, wait for green, hit it. Then see how your thumb compares with the fastest it has ever been. NINE DRILLS, EACH WITH ITS OWN TOP TEN ⢠Reaction ā hit green as fast as you can. One reaction, in milliseconds. ⢠Go / No-Go ā tap green, hold still on red. A tap on red ends the run. ⢠Precision stop ā a 3-2-1 count, then stop the clock on exactly 1.000 s. The digits hide after 0.3 s. ⢠Aim trainer ā twenty targets, one at a time, anywhere on the screen. ⢠Choice reaction ā two pads go amber, one turns green. Tap that one. ⢠Tap speed ā as many taps as you can in five seconds. ⢠Sequence memory ā nine tiles light up in a growing, quickening sequence. Repeat it. ⢠Math sprint ā ten quick sums, four answers each. Pick +, ā, Ć, Ć· or a mix. ⢠Number hunt ā a 6Ć6 grid of numbers. Tap them by the rule: up, down, evens or odds. IT TALKS BACK Miss your personal best and the app has opinions. Mostly ragebait, occasionally encouragement, and it gets sharper the longer the cold streak runs. False starts, taps on red and wrong pads get their own lines. Mute it in Settings if you would rather suffer in silence. EVERY BEST, KEPT The ten best runs of every drill stay on your phone, with podium medals, the top-ten average and a Bests tab you can filter by drill and mode. Each drill knows whether lower or higher is better, so records work for times and counts alike. BRAG WITH ONE TAP Any run becomes a score card in the app's own style, painted in whatever theme you are using and tagged with your username, ready for the share sheet. OFFLINE BY DESIGN No accounts, no network, no leaderboard, no ads, no tracking. Your scores never leave the phone. ALSO IN THE BOX ⢠Light and dark themes that follow your system setting, with a manual override. ⢠Haptics on arm, hit, new record and false start. ⢠A daily brain-boost tip on the home screen: sleep, hydration, posture, timing. ⢠A drill of the day and a jump-back-in card for the last drill you played. ⢠A thirty-second tour the first time you open it. Thirty seconds to learn, a lifetime to master. Hit green.

Verdict
The clearest difference is in-app purchases: Reflex at none against Reaction Test's 7. Reflex also leads on ads (none vs shown). Reaction Test's advantage is update cadence (every 2 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.
