# 妙懂物理 vs 三五小星

妙懂物理 and 三五小星 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. 妙懂物理 sells 3 one-off in-app purchases and 三五小星 sells 12 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 19, 2026 and September 21, 2026 respectively.
