Verdict

The clearest difference is price: Find the Note at Free against Key Detect's $2.99. Find the Note also leads on review sentiment (75% vs 32%) and rating (4.5 vs 2.2). Key Detect's advantage is in-app purchases (none vs 1) and ads (none vs shown). On update cadence and device support there is nothing between them.
