# JWT vs Altheon

Both are free to download. JWT sells 3 in-app purchases, starting at $1.99 per month. Altheon asks for nothing beyond the download.

Altheon holds the better App Store score, 5.0 against 4.7.

JWT ships an update every 5 days, Altheon every 2 days. The most recent releases landed on October 30, 2026 and October 18, 2026 respectively.
