Shikaku Study Log

You are studying, but how far are you from a reasonable target? Shikaku Study Log records study time and practice-question accuracy for Japanese certifications and turns your progress into a clear, private dashboard. ■ Timer and manual entries Start a study timer with one tap or add time later in five-minute increments. Review today, this week, your total, and your current study streak. ■ Compare with general hour guides Built-in reference hours cover ten exams and certifications, including real estate, bookkeeping, financial planning, labor and social security, IT, and TOEIC. See your total beside the general guide, remaining hours, and progress rate. ■ Forecast from your current pace Use the last seven days to estimate when you may reach the reference total. If you set an exam date, the app also shows the daily time needed to reach it by then. ■ Practice questions and history Track accuracy by topic, review a study heatmap and weekly totals, and identify weaker areas. An on-device rule-based coach suggests a practical next step from your own records. Records stay on your device and no account is required. A banner ad appears on supported screens; an optional one-time Remove Ads purchase hides it without changing feature access. Study-hour guides and forecasts are general references only. They do not guarantee any exam result.
