# 珍时 vs WakeUP

The clearest difference is in-app purchases: WakeUP at none against 珍时's 15. 珍时's advantage is ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. 珍时 sells 15 one-off in-app purchases. WakeUP asks for nothing beyond the download.

珍时 ships an update fortnightly, WakeUP weekly. The most recent releases landed on October 19, 2026 and October 24, 2026 respectively.
