Verdict
The clearest difference is price: Lucid at Free against Compound Calculator's $0.99. Lucid also leads on in-app purchases (none vs 3). Compound Calculator's advantage is update cadence (every 5 days vs every 2 weeks). On ads, device support and iOS requirement there is nothing between them.
