Verdict
The clearest difference is price: Aeronautical glossary at Free against EC120B's $49.99. Aeronautical glossary also leads on update cadence (every 3 months vs every 25 months) and device support (3 vs 1). EC120B's advantage is in-app purchases (none vs 3) and iOS requirement (18.6 vs 26.2). On ads there is nothing between them.
