Verdict
The clearest difference is price: 妊婦の体重管理 at Free against Pregnancy Timing Chart's $1.99. 妊婦の体重管理 also leads on update cadence (every 2 months vs every 29 months) and iOS requirement (13.0 vs 15.6). Pregnancy Timing Chart's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
