Chroma

Chroma is a single-player color memory game built around one idea: Can you remember what you just saw? How it works Each round, you see a new color to memorize. At the same time, you must answer a simple question: Tap the color from the previous round. That’s it. Sounds easy. Most people think they can. And yet… After a few rounds, something strange happens. You hesitate. You’re sure you remember… and then you tap the wrong one. Again. Not because it’s fast. Not because it’s unfair. But because your short-term memory quietly fails. That moment is the game. What makes Chroma different: • Infinite run – no levels to clear, only how long you can last • 1-back memory gameplay – constantly remembering and recalling • Two modes: Classic: no timer, pure memory pressure; Timed Rush: short timers that expose hesitation • Increasing difficulty – more choices, closer colors, higher confusion It looks calm. Your brain won’t feel calm. Most runs end not with panic — but with a quiet, confused “Wait… why did I tap that?” If you don’t believe it’s this strange, try Chroma.

Verdict
The clearest difference is in-app purchases: Two Second Math Quiz at none against Chroma's 4. Two Second Math Quiz also leads on ads (none vs shown) and iOS requirement (8.0 vs 15.6). Chroma's advantage is update cadence (daily vs every 3 months). On price and device support there is nothing between them.
