# GradingScale vs SyllySync

The clearest difference is rating: SyllySync at 5.0 against GradingScale's 3.8. SyllySync also leads on update cadence (every 4 days vs every 93 months). GradingScale's advantage is in-app purchases (none vs 4) and review sentiment (67% vs 33%). On price, ads and device support there is nothing between them.

Both are free to download. SyllySync sells 4 in-app purchases, starting at $4.99 per month. GradingScale asks for nothing beyond the download.

SyllySync holds the better App Store score, 5.0 against 3.8. Both are backed by a comparable volume of ratings — 4 and 1 respectively. Written reviews complicate that: 67% of GradingScale's written reviews are positive against 33% of SyllySync's, so the app with the better star average is not the one people write more warmly about.

GradingScale ships an update every 93 months, SyllySync every 4 days. The most recent releases landed on June 3, 2026 and September 9, 2026 respectively.
