Verdict
The clearest difference is price: BirthdayBook at Free against Echo's $3.99. BirthdayBook also leads on update cadence (every 10 days vs every 6 weeks) and iOS requirement (16.0 vs 18.6). Echo's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
