Verdict
The clearest difference is review sentiment: Darwin Security at 100% against AI Optimizer's 40%. Darwin Security also leads on rating (5.0 vs 4.4) and update cadence (every 3 days vs fortnightly). AI Optimizer's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. AI Optimizer sells 4 in-app purchases, starting at $6.99 per 7 days and Darwin Security sells 2 in-app purchases, starting at $10.00 per month. Whichever you choose, the download price is not the number that matters.
Darwin Security holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: AI Optimizer has 181 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 40% of AI Optimizer's written reviews are positive against 100% of Darwin Security's.
AI Optimizer ships an update fortnightly, Darwin Security every 3 days. The most recent releases landed on November 2, 2026 and October 31, 2026 respectively.
