# Feynman AI vs Stellar Math

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.

Both are free to download. Feynman AI sells 5 in-app purchases, starting at $4.99 per 7 days and Stellar Math sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Stellar Math holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Feynman AI has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of Feynman AI's written reviews are positive against 100% of Stellar Math's.

Feynman AI ships an update monthly, Stellar Math every 8 months. The most recent releases landed on September 3, 2026 and August 4, 2026 respectively.
