Verdict

The call

The clearest difference is review sentiment: Claritee at 100% against River Thames Guide's 50%. Claritee also leads on update cadence (every 3 days vs every 6 weeks) and iOS requirement (13.4 vs 16.6). River Thames Guide's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
