# Study Analysis vs 受験カレンダー

The clearest difference is ads: 受験カレンダー at none against Study Analysis's shown. Study Analysis's advantage is update cadence (every 5 days vs every 2 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Study Analysis sells 1 one-off in-app purchase and 受験カレンダー sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Study Analysis ships an update every 5 days, 受験カレンダー every 2 weeks. The most recent releases landed on September 14, 2026 and September 28, 2026 respectively.
