Verdict

The call

The clearest difference is review sentiment: FluentU at 56% against Rosetta Stone's 10%. FluentU also leads on rating (4.3 vs 3.0) and update cadence (fortnightly vs every 2 months). Rosetta Stone's advantage is in-app purchases (none vs 14). On price, ads, device support and iOS requirement there is nothing between them.
