Verdict

The call

The clearest difference is review sentiment: SpeakFlash at 100% against FluentU's 56%. SpeakFlash also leads on rating (5.0 vs 4.3) and monetization model (free with in-app purchases vs subscription). FluentU's advantage is ads (none vs shown) and ratings volume (2.8K vs 3). On price, in-app purchases, device support and iOS requirement there is nothing between them.
