# 小想法 vs PDF

The clearest difference is ads: PDF at none against 小想法's shown. PDF also leads on update cadence (every 2 days vs every 3 weeks). 小想法's advantage is iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 小想法 sells 3 in-app purchases, starting at $0.99 per month and PDF sells 1 in-app purchase, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

小想法 ships an update every 3 weeks, PDF every 2 days. The most recent releases landed on October 16, 2026 and October 20, 2026 respectively.
