# OmniAI vs Co

The clearest difference is ads: Co at none against OmniAI's shown. Co also leads on update cadence (every 9 days vs monthly) and device support (3 vs 1). OmniAI's advantage is ratings volume (7 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. OmniAI sells 3 in-app purchases, starting at $3.99 per 7 days and Co sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for OmniAI against 5.0 for Co. That said, the two scores are not equally well evidenced: OmniAI has 7 ratings behind it against 1, so its average is the more settled of the two.

OmniAI ships an update monthly, Co every 9 days. The most recent releases landed on October 25, 2026 and October 23, 2026 respectively.
