As answered by people managing Study-Track and CodePen.
Study-Track's answer
React/Next.js (TypeScript), Firebase (Firestore + Cloud Functions), Stripe and Resend.
Study-Track's answer
Study-Track is built specifically for students: it turns your class schedule into a simple weekly plan and then helps you track real progress. It combines planning, tasks, and deadlines with time-tracking and progress analytics, without feeling like a heavy project-management tool.
Study-Track's answer
Because it’s designed for student life: fast setup, a clear weekly view, and an easy way to see what’s done vs what still matters. Study-Track prioritizes focus and accountability (progress tracking and streak-friendly habits) instead of bloated features.
Study-Track's answer
Students in higher education (university/college) who juggle lectures, labs, deadlines, and self-study time, and want a straightforward system to plan the week and measure actual study progress.
Study-Track's answer
Study-Track started as a personal project: I couldn’t find a simple tool that helped me plan my week and actually see where my study time went. So I built something minimal and practical that I would genuinely use myself.
Study-Track's answer
Early-stage product: used by students and small study groups (no “enterprise customers” yet).
