Impulse
Read full descriptionHide full description
Twelve games, twelve ways to surprise you. Raw speed, precision, inhibition, anticipation, attention: each game measures something different. Tap Zero for raw reaction time. The Gauge for millisecond precision. Red Light for holding back a movement. Stroop for resisting what you read. And eight more. TODAY'S TRIAL Three games, three constraints, one score. The same three legs for everyone, everywhere, drawn from the date itself. Turbo, reversed instructions, sudden death, fog, eclipse: the constraint changes the rules, not just the difficulty. One attempt a day. Being decent everywhere beats being brilliant at one thing. WARE MODE All twelve games back to back, faster and faster, until your five lives are gone. One round, one game, no pause. Or pass the phone around with up to eight players — last one standing wins. TIERS TO CLIMB Bronze, Silver, Gold, Diamond on every game. Every game is scored on the same 0–100 scale, which finally makes a precision, a reaction time and a streak length comparable. A tier once earned is never lost. YOUR PROGRESS, IN NUMBERS Your best reaction time, your curve run after run, your streak of consecutive days. Everything stays on your iPhone: no account, no sign-up, no server. IT WORKS OFFLINE On the subway, on a plane, at the cabin. Only Game Center leaderboards need a connection. BUILT TO BE FAIR Every game is calibrated to the millisecond and measured on a continuous clock: your score depends on neither your iPhone model nor its refresh rate. iOS Reduce Motion is respected, and sound and haptics turn off separately. Impulse is free. A one-time purchase removes the ads. — Studios Raxoon inc. Support: https://apps.raxoon.com/impulse/support Privacy: https://apps.raxoon.com/impulse/privacy

Verdict
The clearest difference is ads: ChainForge at none against Impulse's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.
