Verdict
The clearest difference is rating: RIN Locator at 4.1 against Khee's 1.0. RIN Locator also leads on ads (none vs shown) and monetization model (free vs ad-supported). Khee's advantage is update cadence (every 3 days vs every 18 months) and iOS requirement (12.4 vs 15.6). On price, in-app purchases and device support there is nothing between them.
