By detecting the user agent, websites can change their behavior appropriately (such as by disabling features where not supported).

Verdict
The clearest difference is price: Unagent at Free against iCTides's $0.99. Unagent also leads on update cadence (monthly vs every 7 months) and ratings volume (58 vs 1). iCTides's advantage is rating (5.0 vs 4.4) and iOS requirement (12.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Unagent is free to download; iCTides costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
iCTides holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Unagent has 58 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 44% of iCTides's written reviews are positive against 59% of Unagent's, so the app with the better star average is not the one people write more warmly about.
iCTides ships an update every 7 months, Unagent monthly. The most recent releases landed on September 2, 2026 and September 26, 2026 respectively.
