Good days and bad days aren't random. You just can't see the pattern yet.

The 2pm crash. The random great Tuesday. The Sunday fog. You experience wild swings in energy but have no idea what's causing them. Without tracking how you feel alongside what you eat, how you sleep, and when you exercise, the pattern stays invisible.

You blame willpower or stress for low-energy days, but it's often meal timing, sleep quality, or caffeine cutoff driving the crash

Fitness apps track workouts and food apps track calories, but nothing tracks how those things actually make you feel

You repeat the same habits on your worst days because you never connected the dots between what you did and how you felt

OutLast rates every meal, workout, and activity from Tired to Energized — and connects the dots so you can see exactly what drives your best and worst days

Rate how you feel with every entry

Every time you log a meal, workout, or habit, rate your energy from Tired to Energized. It takes one extra tap and builds a complete energy timeline for your day.

Spot patterns in days

After a week, your energy tracker reveals the patterns. Maybe protein breakfasts give you great mornings. Maybe pasta lunches always precede the 2pm crash. The data shows you.

Optimize what actually matters

Stop guessing and start repeating what works. OutLast shows you which meals, sleep habits, and routines correlate with your highest-energy days — so you can do more of that.

Energy rating on every entry

Rate every meal, workout, supplement, and activity from Tired to Energized. Build a complete energy profile for each day without a separate tracking app.

I finally figured out why Tuesdays were my best day — it was the only day I ate eggs for breakfast and worked out before 9am. Once I saw the pattern, I replicated it and now most days feel like Tuesday.

Tracks energy, meals & workouts

The 2pm crash was ruining my productivity. OutLast showed me it happened every time I had a carb-heavy lunch. Switched to protein and greens at noon and the crash disappeared within a week.

14-day energy streak

I thought I was just a low-energy person. Turns out my energy was fine on days I slept before 11pm and skipped afternoon caffeine. Having the actual data changed everything.
