Verdict

The call

The clearest difference is review sentiment: STL Master at 86% against The Vector Converter's 22%. STL Master also leads on in-app purchases (none vs 6) and update cadence (monthly vs every 5 months). The Vector Converter's advantage is rating (4.6 vs 4.2) and ratings volume (4.8K vs 49). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

The Vector Converter holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: The Vector Converter has 4.8K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 22% of The Vector Converter's written reviews are positive against 86% of STL Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

The Vector Converter ships an update every 5 months, STL Master monthly. The most recent releases landed on September 25, 2026 and June 8, 2026 respectively.
