# Atomify vs Quantum

The clearest difference is in-app purchases: Atomify at none against Quantum's 6. Atomify also leads on iOS requirement (8.0 vs 26.0). Quantum's advantage is update cadence (every 5 weeks vs every 7 months) and rating (4.8 vs 4.5). On price, ads and device support there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases. Atomify asks for nothing beyond the download.

Quantum holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Quantum has 133 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 75% of Atomify's written reviews are positive against 86% of Quantum's.

Atomify ships an update every 7 months, Quantum every 5 weeks. The most recent releases landed on October 16, 2026 and October 11, 2026 respectively.
