# LotDate vs 查妆助手

The clearest difference is review sentiment: 查妆助手 at 100% against LotDate's 46%. 查妆助手 also leads on rating (5.0 vs 4.7) and iOS requirement (13.0 vs 18.0). LotDate's advantage is ads (none vs shown) and update cadence (every 4 days vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. LotDate sells 3 in-app purchases, starting at $2.99 per month and 查妆助手 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

查妆助手 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: LotDate has 231 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 46% of LotDate's written reviews are positive against 100% of 查妆助手's.

LotDate ships an update every 4 days, 查妆助手 every 3 months. The most recent releases landed on October 11, 2026 and September 30, 2026 respectively.
