Study Sprint Timer vs Yanlış Defteri

Study Sprint Timer is an offline focus timer for students who want to start studying and actually keep going. A small scholarly owl keeps you company: study daily and it thrives, skip a day and it misses you. You open it and start with one tap. Pick a 20 or 40 minute sprint, or set a length of your own. When you cannot tell how long the library day will run, switch to Free Study: an open-ended stopwatch that counts toward your streak and picks up where it left off even after a force quit. The timer sits on the Lock Screen and in the Dynamic Island, with pause and finish buttons right there. The Apple Watch app has a timer of its own. If you came here to read, say so during setup and the app reshapes itself around it: your current book on the home screen, pages instead of coursework. You start a session with a book and, if you want, a page goal, and the summary tells you how far you got. It measures your own pace to estimate how much reading time the book has left. Set a yearly book goal in Settings and watch your library fill up. Every day you study fills one square of the year heatmap. Your weekly chart, personal records and most productive hours live on the stats screen, and the calendar view follows your streak day by day. You can export your whole history as CSV, and write finished sessions to Apple Health as mindful minutes. You decide how it looks. There are 26 light and dark themes, and you can preview each one across the whole app before committing; the app icon changes colour along with the theme. You name the categories yourself: maths, English, software, whatever you happen to be studying. Snooze-able smart alarms and motivation reminders are there too. It was built with high school and university students, self-learners and bootcamp students in mind. It works just as well if you are preparing for exams like YKS, LGS, KPSS or IELTS, or if you are a remote worker who likes the pomodoro rhythm. You do not need an account, and there is no backend of ours behind the app. Analytics runs only if you allow it and never collects what you study, so your study data stays on your phone. Premium is optional. It removes ads for good, unlocks every theme, and keeps an independent developer going. Something feels off? Tell us from Settings. We read every message.

Everyone knows they should keep a mistake notebook. The hard part is not starting one — it is keeping it up. Mistake Notebook is not an archive that collects photos of questions. It is a study system that brings each mistake back when it is due, and refuses to call it closed until you have proved you have learned it. HOW IT WORKS 1. Capture and tag Photograph the question you got wrong. Pick the subject, the topic and, if you like, the type of error — knowledge gap, mixed-up concept, careless slip, ran out of time. No copying anything out. With batch capture you can add every mistake from one practice test in a row. 2. Solve it when it is due The question comes back on a day scheduled around the forgetting curve: after two days, then five. The answer stays hidden. You solve it on paper again and mark yourself honestly. 3. Prove it and close it A mistake is not closed until you have solved it correctly on two different days. One correct answer may just be recall. Two independent ones point to learning. Closed mistakes move to the archive, and your notebook gets smaller. FOR STUDENTS One question each morning: how many reviews do I have today? Logging takes under a minute, so it stays sustainable even during exam week. Every closed mistake is visible progress — no points, no badges, no games. Your subjects and topics are yours to define. Whatever exam board or curriculum you follow, you build the list that matches your own syllabus. FOR TEACHERS Students can share a weekly report if they choose to. The science teacher gets science data only; the maths teacher gets maths data only. In a few seconds you can see which topic and which type of error is causing trouble — useful when setting extra work or planning revision. The report answers "which gap is still open?" rather than "how many questions did they do?" FOR PARENTS Instead of "have you studied?", a concrete picture: open, stubborn and closed mistakes, broken down by subject. No social feed, no chat, no ads. PRIVACY Everything stays on your device. Question photos, notes and review records are never sent to a server. There is no account, no sign-up and no advertising ID. The app works fully offline — on the bus, in the library, out of range. Camera access is used only to photograph a question. For the gallery, the app uses your phone's photo picker and can reach only the image you select. It never scans your photo library. You can export everything to a single backup file at any time, and delete everything with one action. ALSO INCLUDED - Voice notes: say where you got stuck, in your own words - Annotation: circle the step where it went wrong, hide the option you picked - Practice exam tracking: watch your score change over time - Pre-exam sweep: go through any topic again without changing your schedule - Multiple notebooks: siblings can share one phone - Daily reminders, only on days when something is actually due - Available in English, Spanish and Turkish Free. No ads. No subscription. No account.
