EstudyLog is a productivity and education iOS app (iOS 17.6+) built to help you study with more structure and awareness. It combines course organization, a focused study timer, and performance insights so you can track what you did, how long you did it for, and when you tend to perform best. Instead of being just a timer or just a notes app, EstudyLog connects your study sessions to your courses and topics, then turns that data into charts and patterns you can actually use.
When you first open EstudyLog, the app encourages you to start by adding your courses. A course in EstudyLog is more than just a name—it’s a place where all of your studying for that subject stays organized. When you create a course, you can enter the course name and choose a course color to visually distinguish it from your other courses. You can also add a goal date, and optionally a final exam date, which is used to infer a target amount needed for each topic in your course outline. If you want, you can also add key dates like quizzes or tests, and you can paste in your course outline as well. When an outline is provided, EstudyLog sends it to the server to extract the related topics. For this to work correctly, the outline needs to be in a valid format so the server can recognize and parse the structure.
Once your course is set up, you can begin logging real study sessions with a built-in timer. Each session is attached to a specific course and includes a session type so you can track what kind of work you’re doing. EstudyLog currently supports Reading, Practice, Review, and Assignment session types. If you added a proper course outline earlier, the app also lets you choose the topic (or topics) you worked on during that session. You can assign up to three topics per session, and over time this builds a clear picture of how much coverage you’re getting per topic within each course.
EstudyLog also supports note-taking while you study, so you don’t have to separate “tracking time” from “writing down what you learned.” While the timer is running, you can pause or cancel a session at any time. You can also tap the timer card to add or edit notes during the session, which is especially useful for watching lectures and taking notes at the same time. Those notes stay attached to that specific study session, so later you can return and remember what you were working on and what you learned.
When you’re done studying, you finish the timer and rate your session on a scale from 1 to 5. Every session starts with a default rating of 3, and you can adjust it based on how focused or productive that session felt. This rating is a crucial part of the system because it feeds the Insights feature—especially the charts that aim to identify your biological peak hours and performance patterns. After your first session, your dashboard begins to populate with useful summaries: your recent sessions appear, your streak card becomes active, and your quick stats start updating with totals like your total sessions, your average rating, and your total hours. You’ll also see study volume charts that let you understand your progress over time, including daily totals shown across a 7-day span or a 30-day span.
If you ever want to revisit a past session, you can open the relevant course screen, find the session, and update the notes. EstudyLog intentionally limits editing for consistency: only the notes are editable after saving, and you can’t change the session type or the start and end times once a session has been logged. This keeps your timeline and analytics accurate and prevents the data from shifting in ways that would make your insights unreliable.
EstudyLog also includes a Calendar tab with a monthly contribution heat map that makes your consistency easy to see at a glance. Brighter cells represent more study hours on that day, so you can quickly spot your strong weeks, lighter periods, and overall patterns in your schedule without digging through individual sessions.
The most important feature of EstudyLog is the Insights tab. After you’ve logged your first session, the app will show you two core charts: a Time of Day Focus chart that helps you identify your biological peak hours—when you tend to study best—and a Day of Week Focus chart that highlights which days you consistently perform the strongest. As you log more sessions, EstudyLog also generates insight cards for each chart to summarize what the data is saying about your habits and study patterns, helping you understand not just how much you studied, but when you do your best work.
Finally, if you want a deeper view of your progress for a specific course, you can open the Courses tab and review course-level stats and history. Each course shows you a clearer breakdown of your activity and performance, including things like your best study day for that course, your total sessions, your average session length, your average rating, and your total hours by session type. Seeing a lot of reading with little review is a red flag for “mass reading” and weak active recall; balanced practice/review hours tell you you’re actually consolidating what you read. Over time, this makes it easier to see which courses you’re keeping up with, which ones need attention, and how your study behavior changes across different subjects.
In short, EstudyLog is designed to help you turn studying into something measurable, trackable, and improvable—by organizing courses and topics, timing real sessions, capturing notes and ratings, and transforming that information into charts and insights that reveal your best study patterns.
