Verdict
The clearest difference is price: Essential Sci at Free against DrakeEquation's $0.99. Essential Sci also leads on update cadence (every 6 weeks vs every 10 months) and device support (4 vs 2). DrakeEquation's advantage is in-app purchases (none vs 2) and ads (none vs shown). On iOS requirement there is nothing between them.
