# Memory Skill Elevator vs Propel

The clearest difference is in-app purchases: Memory Skill Elevator at none against Propel's 15. Memory Skill Elevator also leads on review sentiment (63% vs 44%) and iOS requirement (12.1 vs 16.0). Propel's advantage is update cadence (every 11 days vs every 2 months) and rating (4.8 vs 4.6). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Propel sells 15 in-app purchases, starting at $4.99 per 7 days. Memory Skill Elevator asks for nothing beyond the download.

Propel holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 310 and 908 respectively. Written reviews complicate that: 63% of Memory Skill Elevator's written reviews are positive against 44% of Propel's, so the app with the better star average is not the one people write more warmly about.

Memory Skill Elevator ships an update every 2 months, Propel every 11 days. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
