By understanding your body clock (chronotype), you can find the best times for focus, rest, and action. This app helps you turn your diagnosis into real, daily behavior. 【About】 Our energy levels, sleepiness, and performance are strongly influenced by our body clock (chronotype). Even if we live similar lives, some people feel sharp in the morning, while others focus better at night. These differences are natural. Based on well-known chronotype concepts, this app analyzes your body clock and shows you when and how to act throughout your day in a simple, practical way. 【Features】 ■ Body Clock (Chronotype) Test Answer a short set of questions to discover your chronotype. We analyze whether you lean toward a morning, intermediate, or evening type and identify your most productive time periods. ■ Time-Based Action Guide Easily see when you are likely to focus best, when to rest, and when to take things more lightly. This app is designed to be useful in daily life—not just a one-time test. ■ Real-Time Advice Get simple action tips based on your current time of day. You can adjust your behavior naturally, without overthinking. ■ Widget Support Check advice for your current time directly from your home screen.
