# Noji vs FlashStacks

Noji and FlashStacks both sit at 4.6 stars, but that hides the real split: 100% of FlashStacks's written reviews are positive against 64% of Noji's. FlashStacks also leads on ads (none vs shown). Noji's advantage is ratings volume (14K vs 7). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Noji sells 10 in-app purchases, starting at $4.99 per month and FlashStacks sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Noji against 4.6 for FlashStacks. That said, the two scores are not equally well evidenced: Noji has 14K ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 64% of Noji's written reviews are positive against 100% of FlashStacks's.

Both ship on a similar rhythm, roughly every 8 days. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
