# TSF vs CLAZZ

The clearest difference is in-app purchases: CLAZZ at none against TSF's 2. CLAZZ also leads on review sentiment (89% vs 56%). TSF's advantage is ads (none vs shown) and update cadence (every 5 weeks vs every 15 months). On price, rating, ratings volume and iOS requirement there is nothing between them.

Both are free to download. TSF sells 2 in-app purchases, starting at $3.99 per month. CLAZZ asks for nothing beyond the download.

TSF holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 3 and 6 respectively. Written reviews complicate that: 56% of TSF's written reviews are positive against 89% of CLAZZ's, so the app with the better star average is not the one people write more warmly about.

TSF ships an update every 5 weeks, CLAZZ every 15 months. The most recent releases landed on September 7, 2026 and September 24, 2026 respectively.
