# Java程序设计 vs MSDC

The clearest difference is in-app purchases: MSDC at none against Java程序设计's 1. MSDC also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 3 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Java程序设计 sells 1 one-off in-app purchase. MSDC asks for nothing beyond the download.

Java程序设计 ships an update every 3 months, MSDC every 2 weeks. The most recent releases landed on June 1, 2026 and September 15, 2026 respectively.
