# Auto Agent vs Ultra Boost

The clearest difference is in-app purchases: Ultra Boost at none against Auto Agent's 6. Ultra Boost also leads on review sentiment (100% vs 75%) and iOS requirement (12.0 vs 15.0). Auto Agent's advantage is ratings volume (43K vs 4). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Auto Agent sells 6 one-off in-app purchases. Ultra Boost asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Auto Agent against 5.0 for Ultra Boost. That said, the two scores are not equally well evidenced: Auto Agent has 43K ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 75% of Auto Agent's written reviews are positive against 100% of Ultra Boost's.

Auto Agent ships an update every 3 months, Ultra Boost every 2 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
