Understand the cognitive principles and deterministic algorithms powering your daily study sessions.
Passive studying (re-reading notes or watching video lectures without testing) produces an illusion of competence. StudyOS enforces active cognitive retrieval:
Your readiness score is computed deterministically using 7 weights:
If you have 5 unresolved calculation mistakes, your readiness drops by 12.5% until you re-verify those problems in a practice session.
To add a tuition test or coaching mock paper:
Whenever you score less than full marks in a mock test or practice quiz:
Everything you need to know about StudyOS's features, privacy, and architecture.
No. StudyOS is engineered from the ground up as an offline-first system. All your subjects, chapters, flashcards, mock tests, mistake logs, and algorithms run inside your device's local Room SQLite database. You can use it in airplane mode, subway commutes, or study halls without internet.
StudyOS registers system-level exact alarms with Android's native AlarmManager. When your timer reaches zero, Android triggers a high-priority notification channel with audio alerts and vibration, ensuring you never miss the end of your study or break session even during deep sleep.
In the StudyOS Settings screen, tap AI Configuration. You can paste your own OpenAI or Google Gemini API key. The key is encrypted locally using Android Keystore and EncryptedSharedPreferences. StudyOS communicates directly with the AI API endpoint without passing through any intermediary proxy servers.
Major exams (like final board or university papers) are terminal goals with high stakes. In contrast, tuition quizzes and mock papers are diagnostic tests meant to discover weak spots. StudyOS provides a separate tab filter, exact time-of-day pickers, and direct links to the Mistake Bank so that coaching tests help you improve rather than creating unnecessary panic.
100%. StudyOS contains zero third-party analytics trackers, zero marketing telemetry, and no remote database sync. Everything remains on your device under your complete ownership.
