ThinkLeft

ThinkLeft tracks your cognitive fatigue so you make better decisions at the right time of day.

Your brain doesn't run at full power all day. Every decision — what to eat, which email to answer, whether to take that meeting — drains mental energy. ThinkLeft scores your cognitive load in real time so you can see exactly when you're sharp and when you're running on fumes.

KEY FEATURES

• Real-Time Fatigue Score — A 0–100 score updated throughout the day based on 4 signals: decisions made, time of day, fidgeting (restlessness), and app hopping (context switching).

• Peak Hour Detection — Know your personal peak focus window and afternoon slump based on your wake time and daily patterns.

• One-Tap Decision Logger — Track important decisions in under 2 seconds. Look back and spot the hours you decide best.

• Weekly Insights — See your peak days, average scores, and decision volume patterns over time.

• Focus Mode — Hide the score when you just want to work without obsessing over the number.

• Schedule Profiles — Early Bird, Standard, Night Owl, Night Shift, and Custom wake times shift the fatigue curve to match your life.

• Personal Baseline — After a few days of use, ThinkLeft calibrates to your normal range so the score is relative to you.

• Home Screen Widget — Glance at your current fatigue score without opening the app.

Stop guessing when to tackle hard decisions. Know when your brain is ready.
