Verdict

The call

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.
