Verdict

The call

The clearest difference is ads: Stellar Math at none against Feynman AI's shown. Stellar Math also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 75%). Feynman AI's advantage is update cadence (monthly vs every 8 months) and ratings volume (14 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
