# LockStart vs 全屏时钟

The clearest difference is in-app purchases: 全屏时钟 at none against LockStart's 1. 全屏时钟 also leads on update cadence (daily vs every 6 days). LockStart's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. LockStart sells 1 one-off in-app purchase. 全屏时钟 asks for nothing beyond the download.

LockStart ships an update every 6 days, 全屏时钟 daily. The most recent releases landed on May 17, 2026 and September 18, 2026 respectively.
