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 43% 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 September 23, 2026 and September 26, 2026 respectively.
