# ATOM vs Mulchat

The clearest difference is rating: Mulchat at 5.0 against ATOM's 3.4. Mulchat also leads on review sentiment (67% vs 44%). ATOM's advantage is in-app purchases (none vs 3) and ratings volume (5 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Mulchat sells 3 in-app purchases, starting at $3.99 per 7 days. ATOM asks for nothing beyond the download.

Mulchat holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: ATOM has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 44% of ATOM's written reviews are positive against 67% of Mulchat's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on August 12, 2026 and September 10, 2026 respectively.
