# Feynman AI vs Quantify

The clearest difference is in-app purchases: Quantify at none against Feynman AI's 7. Quantify also leads on rating (5.0 vs 4.6) and iOS requirement (15.5 vs 18.6). Feynman AI's advantage is ads (none vs shown) and ratings volume (50 vs 5). On price, update cadence and device support there is nothing between them.

Both are free to download. Feynman AI sells 7 in-app purchases, starting at $2.99 per 7 days. Quantify asks for nothing beyond the download.

Quantify holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Feynman AI has 50 ratings behind it against 5, so its average is the more settled of the two.

Feynman AI ships an update every 6 days, Quantify every 5 days. The most recent releases landed on September 29, 2026 and October 3, 2026 respectively.
