You're quitting sugar. Now track the proof.

30-day no-sugar challenges are everywhere — but nobody is tracking them. You cut out sugar, your cravings are brutal for a week, and then something shifts. But you have zero data. When did cravings peak? When did energy stabilize? OutLast is the first sugar free tracker: log your no-sugar days in one tap, build streaks, and finally see the real connection between cutting sugar and better energy, sleep, and mood.

You're white-knuckling it. With zero data.

You watched Lustig or Hyman, read the research, and decided to quit sugar. You're powering through cravings and swear you feel better. But you can't prove it. You don't know that cravings peaked on day 5 and vanished by day 12. You can't correlate sugar-free days with better energy and sleep. Without tracking, you'll quit before the benefits kick in.

You can’t see that cravings peaked on day 5 and vanished by day 12 because you’re not logging them

You can’t correlate sugar-free days with better energy and sleep because nobody is tracking both

Without data showing the benefits are real, you’ll break the streak before the payoff kicks in

OutLast lets you log every sugar-free day in one tap, track cravings, build streaks, and finally see how cutting sugar is actually improving your energy, sleep, and mood

Log your sugar-free day

One tap at the end of the day. OutLast timestamps your entry and adds it to your streak automatically. Note your craving level — mild, moderate, or intense — so you can watch them fade over time.

Track cravings, energy, and sleep

Log how strong your cravings were and how your energy and sleep felt. Over time, you’ll build a dataset that shows exactly when the benefits of going sugar-free start kicking in.

See the sugar-free difference

Your streak, craving trends, and energy scores tell the real story. Watch cravings drop, energy stabilize, and sleep improve — with data, not guesswork.

I’ve tried quitting sugar three times. This time I logged every day with OutLast and I could actually see my cravings dropping after day 8. Having that data made me push through instead of caving at the two-week mark.

30-day sugar-free streak

I started a no-sugar challenge with friends. I was the only one using OutLast to track and I was the only one who finished. Seeing my streak and my energy scores climb was all the motivation I needed.

Tracks sugar-free + energy daily

My doctor asked if cutting sugar helped my energy. Instead of saying ‘I think so,’ I showed her my OutLast data — 21 sugar-free days with steady energy improvement after day 10. She was genuinely impressed.
