# OmniAI vs Exponential

The clearest difference is in-app purchases: Exponential at none against OmniAI's 3. Exponential also leads on ads (none vs shown) and update cadence (every 5 days vs monthly). OmniAI's advantage is ratings volume (10 vs 2). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. OmniAI sells 3 in-app purchases, starting at $3.99 per 7 days. Exponential asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for OmniAI against 5.0 for Exponential. That said, the two scores are not equally well evidenced: OmniAI has 10 ratings behind it against 2, so its average is the more settled of the two.

OmniAI ships an update monthly, Exponential every 5 days. The most recent releases landed on October 28, 2026 and October 31, 2026 respectively.
