FlashDigits is a fast, minimal memory game built to test your brain’s limits in under two seconds. You’re shown a random number—just for 1.5 seconds. Then it disappears. Type it back in. Sounds easy? It isn’t. Each correct answer adds to your streak and makes the next number longer. One mistake and your run is over. There are no distractions—no ads, no power-ups, no extra lives. Just you, the numbers, and the blink of time.

Verdict
The clearest difference is in-app purchases: FlashDigits at none against Pi's 6. Pi's advantage is update cadence (every 3 months vs every 9 months) and iOS requirement (15.0 vs 18.4). On price, ads and device support there is nothing between them.
