# Levin vs Halo AI

The clearest difference is ads: Halo AI at none against Levin's shown. Halo AI also leads on update cadence (every 4 days vs every 10 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Levin sells 1 in-app purchase, starting at $3.99 per month and Halo AI sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Levin ships an update every 10 days, Halo AI every 4 days. The most recent releases landed on October 18, 2026 and October 11, 2026 respectively.
