# Underlist vs ChatLLM

The clearest difference is rating: ChatLLM at 4.9 against Underlist's 4.3. ChatLLM also leads on review sentiment (64% vs 33%) and update cadence (every 4 days vs monthly). Underlist's advantage is monetization model (free vs subscription) and device support (4 vs 2). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Underlist sells 5 in-app purchases, starting at $0.99 per month and ChatLLM sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ChatLLM holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: ChatLLM has 3.8K ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 33% of Underlist's written reviews are positive against 64% of ChatLLM's.

Underlist ships an update monthly, ChatLLM every 4 days. The most recent releases landed on September 25, 2026 and October 23, 2026 respectively.
