# SkewTLogPro vs FBOlink

The clearest difference is rating: FBOlink at 3.6 against SkewTLogPro's 2.7. FBOlink also leads on monetization model (free vs subscription) and iOS requirement (15.6 vs 17.0). SkewTLogPro's advantage is review sentiment (47% vs 8%) and ratings volume (97 vs 12). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. SkewTLogPro sells 1 in-app purchase, starting at $12.99 per year and FBOlink sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

FBOlink holds the better App Store score, 3.6 against 2.7. That said, the two scores are not equally well evidenced: SkewTLogPro has 97 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 47% of SkewTLogPro's written reviews are positive against 8% of FBOlink's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 23, 2026 and June 1, 2026 respectively.
