# ソナエノート vs Day

The clearest difference is in-app purchases: ソナエノート at none against Day's 1. Day's advantage is ads (none vs shown) and update cadence (every 3 days vs every 9 days). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Day sells 1 one-off in-app purchase. ソナエノート asks for nothing beyond the download.

ソナエノート ships an update every 9 days, Day every 3 days. The most recent releases landed on October 25, 2026 and October 7, 2026 respectively.
