Verdict
The clearest difference is in-app purchases: 雙重驗證 at none against Password 4 Pro's 3. 雙重驗證 also leads on ads (none vs shown) and device support (4 vs 2). Password 4 Pro's advantage is update cadence (fortnightly vs every 8 months). On price and iOS requirement there is nothing between them.
