# SkewTLogPro vs Coflyt

The clearest difference is rating: Coflyt at 4.1 against SkewTLogPro's 2.7. Coflyt also leads on in-app purchases (none vs 1) and iOS requirement (13.4 vs 17.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

Both are free to download. SkewTLogPro sells 1 in-app purchase, starting at $12.99 per year. Coflyt asks for nothing beyond the download.

Coflyt holds the better App Store score, 4.1 against 2.7. Both are backed by a comparable volume of ratings — 97 and 50 respectively. Written reviews complicate that: 47% of SkewTLogPro's written reviews are positive against 42% of Coflyt'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 October 8, 2026 and October 12, 2026 respectively.
