Everything you need to
protect your energy

Thoughtfully designed tools that work with your natural energy rhythms, not against them.

🔋

Live Energy Battery

Your 0–100% mental battery updates in real time. Color shifts green → yellow → red as your energy drops so you always know where you stand at a glance.

Energy-Aware Tasks

Each task has an energy cost. The app only shows tasks you can actually complete right now — no more overwhelming to-do lists that set you up to fail.

Quick Recharges

Log a short break, a chocolate bar or a quick nap and instantly recover energy. Premium users can create unlimited custom recharge presets.

🔔

Smart Reminders

Set recurring reminders (daily, weekly, monthly, yearly) with advanced notifications up to a week ahead. Never forget a bill or important date again.

Three steps to a
better day

Start in seconds. No complicated setup, no learning curve.
