# Physics Zen vs Physics Handbook

Physics Zen and Physics Handbook are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Physics Zen sells 6 in-app purchases, starting at $3.99 per 7 days and Physics Handbook sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Physics Zen ships an update every 3 days, Physics Handbook every 5 days. The most recent releases landed on November 10, 2026 and November 13, 2026 respectively.
