# Lean AI vs BodyBoost

Both are free to download. Lean AI sells 14 in-app purchases, starting at $0.99 per 7 days. BodyBoost asks for nothing beyond the download.

Lean AI ships an update every 3 days, BodyBoost every 10 days. The most recent releases landed on September 21, 2026 and September 8, 2026 respectively.
