# 标准放大镜 vs Compass

The clearest difference is in-app purchases: 标准放大镜 at none against Compass's 5. 标准放大镜 also leads on iOS requirement (11.0 vs 13.0). Compass's advantage is update cadence (every 2 weeks vs every 5 months). On price, ads and device support there is nothing between them.

Both are free to download. Compass sells 5 in-app purchases, starting at $9.99 per 7 days. 标准放大镜 asks for nothing beyond the download.

标准放大镜 ships an update every 5 months, Compass every 2 weeks. The most recent releases landed on September 30, 2026 and October 16, 2026 respectively.
