# iBoost vs Sophon

The clearest difference is rating: iBoost at 5.0 against Sophon's 4.2. iBoost also leads on in-app purchases (none vs 12). Sophon's advantage is update cadence (every 9 days vs every 5 months) and review sentiment (29% vs 0%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Sophon sells 12 in-app purchases, starting at $6.99 per month. iBoost asks for nothing beyond the download.

iBoost holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Sophon has 56 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of iBoost's written reviews are positive against 29% of Sophon's, so the app with the better star average is not the one people write more warmly about.

iBoost ships an update every 5 months, Sophon every 9 days. The most recent releases landed on October 8, 2026 and October 16, 2026 respectively.
