The problem
Students preparing for Indian competitive exams juggle huge syllabi with limited hours. Most apps hand them a question bank or a static timetable that breaks the first week they fall behind, and then they are left guessing what to do with their next hour.
The approach
Prepology turns a learner's goal, free time and progress into a personalised daily plan. It looks at the exam date, syllabus coverage, practice answers and retention, picks the next best task with a reason attached, and rebuilds the plan when life gets in the way. Say you only have an hour left: the most important block stays, one gets shorter, and the rest move off today.
What it does
Every part earns its place.
Practice at your level
Questions are pitched so learners get most, but not all, right. Ability updates after every answer, and each explanation covers why the wrong options are tempting.
Revision before you forget
Every concept practised gets a review date from the FSRS spaced-repetition model, tightened as the exam gets closer.
Honest progress
Readiness is shown together with how much of the exam it is based on. Untouched topics read "not assessed", never 0% and never mastered.
Exam-true mock tests
Topics follow each exam's published syllabus and timed mocks follow its pattern, with MCQ, multi-select and numerical-answer questions.
AI mentor
A guardrailed assistant explains questions and the plan, with daily quotas and moderation on every message.
Under the hood
Flutter ships one codebase to Android and the web, so the plan, practice and progress stay identical on every device. The API is a small Hono service with Zod validation on every route, backed by Supabase Postgres through Drizzle. Production runs on a single Oracle Cloud VM behind a Cloudflare Tunnel: no inbound ports are open, and Cloudflare handles TLS, WAF and caching.
