# Thesys vs LoAdKer

The clearest difference is in-app purchases: LoAdKer at none against Thesys's 1. LoAdKer also leads on review sentiment (70% vs 59%) and iOS requirement (12.0 vs 17.6). Thesys's advantage is rating (4.7 vs 4.3) and ratings volume (85 vs 13). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Thesys sells 1 one-off in-app purchase. LoAdKer asks for nothing beyond the download.

Thesys holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Thesys has 85 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 59% of Thesys's written reviews are positive against 70% of LoAdKer's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 16, 2026 and October 13, 2026 respectively.
