# Atoms vs Milestone

The clearest difference is review sentiment: Milestone at 100% against Atoms's 56%. Milestone also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). Atoms's advantage is ratings volume (11K vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Atoms sells 2 in-app purchases, starting at $4.99 per month and Milestone sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Milestone holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Atoms has 11K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 56% of Atoms's written reviews are positive against 100% of Milestone's.

Atoms ships an update every 2 weeks, Milestone every 4 weeks. The most recent releases landed on October 15, 2026 and October 11, 2026 respectively.
