Challenge

Students and teachers were juggling separate apps for assignments, events, and notes — none of them connected. Deadlines slipped. Workloads were invisible. Collaboration happened over email, if at all.

No single tool showed a student what was due, when, and how much was left to do. No single tool showed a teacher which students were falling behind.

Key challenges:

  • Fragmented tools: assignments, events, and notes lived in separate, disconnected apps
  • Missed deadlines: nothing surfaced what was due, when, and how much was left
  • Invisible workloads: students had no view of priorities or workload distribution
  • No early warning: teachers couldn't see which students were falling behind
  • Email-only collaboration: feedback and updates were scattered and untracked

Solution

We built a unified mobile platform for academic planning — one place for assignments, deadlines, events, notes, reminders, and performance data — with a strong focus on productivity, real-time collaboration, and structured academic workflow. A team of 5 shipped in 4 months: 2 mobile app developers, 1 backend engineer, 1 PM + QA lead, and 1 product designer.
