# Thermals vs HTML Editor

The clearest difference is review sentiment: Thermals at 83% against HTML Editor's 22%. Thermals also leads on in-app purchases (none vs 2) and rating (4.5 vs 4.2). HTML Editor's advantage is ratings volume (819 vs 28) and chart position (#58 vs #175). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. HTML Editor sells 2 in-app purchases, starting at $2.99 per 7 days. Thermals asks for nothing beyond the download.

Thermals holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: HTML Editor has 819 ratings behind it against 28, so its average is the more settled of the two. Written reviews point the same way: 83% of Thermals's written reviews are positive against 22% of HTML Editor's.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
