It guides you through problems and to your own a-ha moments. So while you’re learning, you’re also building critical thinking and analytical skills – and having fun.

Verdict

The call

The clearest difference is ads: DataExpert / TechExpert at none against Brilliant's shown. DataExpert / TechExpert also leads on rating (5.0 vs 4.7). Brilliant's advantage is ratings volume (33K vs 1) and update cadence (weekly vs every 3 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
