Verdict
The clearest difference is price: ClientNote at Free against Chemicalculator's $1.99. ClientNote also leads on update cadence (every 6 weeks vs every 10 months). Chemicalculator's advantage is in-app purchases (none vs 4) and ads (none vs shown). On device support there is nothing between them.
