Verdict

The call

The clearest difference is price: Tureng Dictionary at Free against American Heritage® Dictionary's $12.99. Tureng Dictionary also leads on update cadence (every 2 weeks vs every 2 months). American Heritage® Dictionary's advantage is ads (none vs shown) and review sentiment (66% vs 31%). On in-app purchases, monetization model, device support and iOS requirement there is nothing between them.
