Case study
problem
Students and builders often split tasks, notes, focus sessions, learning reminders and file references across too many tools.
built
I built a Flutter productivity ecosystem with tasks, subtasks, notes, calendar planning, focus tools, notifications, file attachments, media preview and gamified progress.
challenge
The main technical challenge was keeping the app expandable while handling local data relationships, reminders, attachments and multiple productivity flows without making the UI feel crowded.
learned
I learned how database structure, notification timing, offline-first decisions and feature hierarchy affect the everyday feel of a mobile product.
impact
NisanApp now acts as my strongest proof of Flutter product development because it combines useful features, long-term iteration and practical architecture.
Overview
NisanApp began as a task manager and evolved into a broader productivity system for tasks, notes, learning workflows, focus sessions, statistics, settings, and calendar views.
The project strengthened my understanding of local persistence, SQLite modeling, parent-child task relationships, notification scheduling, file metadata, media previews, share flows, and long-term product iteration.
It is positioned as my flagship mobile project because it shows product thinking, Flutter architecture, UI refinement, practical personal initiative, and the difference between cloud-sync and local/offline app delivery.
Highlights
Tasks, subtasks, notes, calendar, focus hub, stopwatch and countdown tools.
SQLite structure with parent task relationships, foreign keys and cascade behavior.
File picker, path provider, local media preview, image zoom, video playback and sharing support.
Gamified XP/levels, spaced repetition logic, notifications and offline-first thinking.
