Verdict
The clearest difference is review sentiment: NJRecalls at 100% against AAサイトビューア's 50%. NJRecalls also leads on ads (none vs shown) and monetization model (free vs ad-supported). AAサイトビューア's advantage is update cadence (every 3 days vs every 2 months) and iOS requirement (11.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.
