# Atom Fusion vs Idle Dice 2

The clearest difference is ads: Atom Fusion at none against Idle Dice 2's shown. Atom Fusion also leads on update cadence (every 5 days vs every 2 months) and review sentiment (100% vs 79%). Idle Dice 2's advantage is rating (4.6 vs 4.3) and ratings volume (83 vs 6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Atom Fusion sells 1 one-off in-app purchase and Idle Dice 2 sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Idle Dice 2 holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Idle Dice 2 has 83 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of Atom Fusion's written reviews are positive against 79% of Idle Dice 2's, so the app with the better star average is not the one people write more warmly about.

Atom Fusion ships an update every 5 days, Idle Dice 2 every 2 months. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
