Custom Google Sheets Habit Tracker

I want a fully-automated habit-tracking spreadsheet built in Google Sheets (Excel compatibility is a plus). It has to handle well over 20 simultaneous habits and let me log results quickly from desktop or mobile. Each entry should immediately update daily and weekly summaries, calculate streaks, and feed clear visual progress charts so I can spot trends at a glance.

Beyond the raw tracking, I need space to set individual goals for every habit and have the sheet flag me—through conditional formatting or lightweight Apps Script email/push reminders—whenever I fall behind. Any formulas, scripts, or named ranges you add should be clean, documented, and easy for me to extend later.

Please deliver:
• A Google Sheet template pre-loaded with sample data, fully functioning dashboards, and goal/reminder logic
• Brief walk-through notes (or a short Loom video) showing how to add new habits, reset periods, and adjust goals

If you have previous tracker examples or clever visualization ideas, feel free to mention them in your proposal; I’m keen to see what’s possible.
