Welcome! I'm Singaseong, an indie developer. I build small, purposeful apps that solve real problems—like tracking students more efficiently, logging everyday tasks, or offering a quick puzzle break to train focus. This hub page introduces each app, explains who it’s for, and links to detailed guides and downloads. If you’re a teacher or student looking for practical tools, you’re in the right place.
What you'll find on this page
- Clear overviews of each app and what problems it solves
- Screenshots and short walkthroughs of key tasks
- Tips for getting started quickly in the classroom
- Links to in-depth guides, FAQs, and store downloads
Manage Students — Keep Class Data Organized
What it is: Manage Students helps teachers keep rosters, notes, and quick assessments in one place. It’s designed for fast daily use: mark attendance, jot quick comments, and export summaries when needed.
Why it helps: Every minute counts in class. Instead of juggling spreadsheets and sticky notes, you can keep everything together and searchable. Over time, your short notes become a meaningful record that informs parent meetings and student support.
How it works (at a glance):
- Create classes and add students individually or import a CSV.
- Record attendance and quick notes during or after class.
- Export to CSV/Excel to share with colleagues or archive.

Log for Everything — A Daily Life Tracker That Sticks
What it is: A flexible logging app for habits, inventories, and small projects. The goal is to make logging quick enough that you’ll actually do it—and structured enough to be useful afterward.
Classroom ideas: Track equipment checkout, club attendance, or quick reflections after lessons. For personal productivity, log workouts, purchases, reading, or household tasks.
Simple flow: pick a category → add a short entry → optionally tag or rate → view summaries.

Gridlock Shooter — A Focus-Training Puzzle Break
What it is: A lightweight puzzle-shooter that rewards timing and pattern recognition. It’s a quick break app—useful between tasks to reset attention and return sharper.
Why it helps: Short, bounded games can refresh focus. In a study hall or at home, a 3–5 minute puzzle helps transition between cognitive tasks.

How I Build These Tools (People-First Principles)
- Frictionless setup: you can use the app meaningfully within minutes.
- Portable data: export to CSV so your information isn’t stuck.
- Privacy by design: only collect what’s needed for the feature; see each app’s privacy section for details.
- Iterative improvements: I ship small updates based on real classroom feedback.
