Verdict

The call

The clearest difference is price: FAR/AIM at Free against Aviation Dictionary's $9.99. FAR/AIM also leads on rating (4.7 vs 3.2) and update cadence (fortnightly vs every 44 months). Aviation Dictionary's advantage is in-app purchases (none vs 1) and chart position (#141 vs unranked). On ads, device support and iOS requirement there is nothing between them.
