Verdict
The clearest difference is in-app purchases: Zumstein 3.0 at none against Librafy's 1. Zumstein 3.0 also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.1). Librafy's advantage is update cadence (fortnightly vs every 5 months). On price and device support there is nothing between them.
