# 得到 vs OZ

The clearest difference is in-app purchases: OZ at none against 得到's 10. 得到's advantage is update cadence (fortnightly vs every 3 months) and chart position (#146 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. 得到 sells 10 in-app purchases, starting at $2.99 per month. OZ asks for nothing beyond the download.

得到 ships an update fortnightly, OZ every 3 months. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
