# 科學人 vs ReadGrow

The clearest difference is update cadence: ReadGrow at every 3 days against 科學人's every 5 weeks. 科學人's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

科學人 ships an update every 5 weeks, ReadGrow every 3 days. The most recent releases landed on September 8, 2026 and August 20, 2026 respectively.
