# 100 moment vs FlashNumbers：Train your memory

The clearest difference is review sentiment: 100 moment at 80% against FlashNumbers：Train your memory's 33%. 100 moment also leads on ratings volume (15 vs 1). FlashNumbers：Train your memory's advantage is rating (5.0 vs 4.1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

FlashNumbers：Train your memory holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: 100 moment has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of 100 moment's written reviews are positive against 33% of FlashNumbers：Train your memory's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 17 months. The most recent releases landed on September 20, 2026 and September 9, 2026 respectively.
