# Source Viewer XL vs Tampermonkey

The clearest difference is rating: Source Viewer XL at 4.7 against Tampermonkey's 3.1. Source Viewer XL also leads on price ($1.99 vs $2.99). Tampermonkey's advantage is update cadence (every 8 months vs every 28 months) and ratings volume (58 vs 3). On review sentiment, ads, in-app purchases and iOS requirement there is nothing between them.

Source Viewer XL costs $1.99 and Tampermonkey $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Source Viewer XL holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: Tampermonkey has 58 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 57% of Source Viewer XL's written reviews are positive against 58% of Tampermonkey's, so the app with the better star average is not the one people write more warmly about.

Source Viewer XL ships an update every 28 months, Tampermonkey every 8 months. The most recent releases landed on September 9, 2026 and September 24, 2026 respectively.
