Learning a language, a new skill, or a professional exam? Set hour goals, build a streak, and watch progress add up week by week.
"I went from cramming the night before to doing two hours a day, every day. My predicted grade jumped two levels — and I wasn't even stressing."
It's a forecast of how many hours you still need per subject before your exam — based on your own pace, focus minutes and goals. The number updates after every session, so it always reflects reality.
Add your subjects, then start a focused session. The diary logs duration, focus drift and your notes automatically. Set a per-subject hour goal and the progress bar fills as you study.
