Verdict

The call

The clearest difference is monetization model: MasterPilot at freemium against SkewTLogPro's subscription. MasterPilot also leads on update cadence (weekly vs every 2 months). SkewTLogPro's advantage is rating (2.7 vs 2.3) and ratings volume (97 vs 3). On price, review sentiment, 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 MasterPilot sells 1 in-app purchase, starting at $259.99 per year. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

SkewTLogPro holds the better App Store score, 2.7 against 2.3. That said, the two scores are not equally well evidenced: SkewTLogPro has 97 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 47% of SkewTLogPro's written reviews are positive against 50% of MasterPilot's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SkewTLogPro ships an update every 2 months, MasterPilot weekly. The most recent releases landed on September 23, 2026 and July 28, 2026 respectively.
