Stop over-scheduling. Mental Battery tracks your energy throughout the day so you only tackle what you truly have capacity for — and finish feeling proud, not drained.
Thoughtfully designed tools that work with your natural energy rhythms, not against them.
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.
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.
Log a short break, a chocolate bar or a quick nap and instantly recover energy. Premium users can create unlimited custom recharge presets.
Set recurring reminders (daily, weekly, monthly, yearly) with advanced notifications up to a week ahead. Never forget a bill or important date again.
Start in seconds. No complicated setup, no learning curve.
Start each morning by setting or confirming your energy level. Slept well? Full 100. Rough night? Maybe 60. Your battery, your rules.
Add tasks with an energy cost. The app filters your list to only what fits your current charge — keeping your day realistic and achievable.
Complete tasks, log recharges, and watch your day unfold with intention. Sync across all your devices via Firebase in real time.
