Energy Tracker

Do you ever wonder why some days you get everything done and others feel like a losing battle? The answer is in your energy — and Energy Tracker helps you decode it.

Energy Tracker is a focus and productivity companion that lets you log your energy level and activity throughout the day, then surfaces powerful analytics to show exactly when and how you perform at your best. Stop guessing. Start optimizing.


WHAT MAKES IT DIFFERENT

Most productivity apps tell you what to do. Energy Tracker shows you when to do it. By tracking your personal energy rhythm over time, the app builds a data-driven picture of your peak focus windows — so you can schedule your most demanding work for the moments you're actually at your sharpest.


KEY FEATURES

• Energy Level Logging — Rate your current state from 1 (Exhausted) to 5 (Peak Focus) with a single tap, powered by an intuitive emoji-based selector
• Activity Tagging — Tag each entry with what you're doing: Coding, Meetings, Reading, Exercising, Eating, Resting, Planning, or Admin Work
• Context Notes — Add a brief note to each log entry for richer recall and pattern recognition
• Peak Focus Analysis — Instantly see your peak focus hour, top productive activity, and best time-of-day period
• 24-Hour Bar Chart — A beautiful teal visualization maps your energy across every hour, with your peak moment highlighted in gold
• Color-Coded Energy Log — Browse your recent entries with vivid color coding: gold for Peak Focus, mint for High Energy, blue for Balanced, purple for Low, coral for Exhausted
• Demo Data Seeding — New to the app? Seed realistic sample data in one tap to explore all features before your first real log
• Lightweight and Fast — No accounts, no subscriptions, no syncing delays — just open and log


HOW IT WORKS

1. Open Energy Tracker at any moment during your day
2. Select your current energy level using the 1–5 emoji scale
3. Tap the activity that describes what you're doing
