Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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