# The Vector Converter vs STL Master

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.

Both are free to download. The Vector Converter sells 6 in-app purchases, starting at $1.99 per month. STL Master asks for nothing beyond the download.

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.

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.
