Track your study or work time with a single tap. At the end of the day, your record becomes a "Kou Card" — a single illustrated page of that day. The 72 Kou are the Japanese microseasons that divide the year into 72 five-day periods. Kiseki ties the hours you put in to the season you spent them in. That is why it keeps being opened, unlike apps that only show you a graph. 【Who it's for】 • Track study hours and feel the progress add up • Manage exam or certification study time by subject • Look back on the hours you spent in deep focus • You have tried tracking apps before and stopped 【Features】 • Track study and work time with a simple timer • Organize by subject or category • Analyze trends with statistics & graphs • Save each day as a Kou Card • Siri Shortcuts support 【What is a Kou Card?】 Each day's work, hours, weather, and location are captured in a single beautiful card — your daily footprints become a timeless collection. 【Premium Features】 • Ad-free experience • Unlimited statistics period • Unlimited categories • Unlimited manual entries • No editing restrictions Start with 30 minutes today. The hours you gather become a trail through the seasons.

Verdict
The clearest difference is ads: 静音日和 at none against Kiseki's shown. Kiseki's advantage is update cadence (fortnightly vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
