Deficit Streak: Diet Tracker

Stay in your calorie deficit every single day. Build an unbreakable streak, see your projected fat loss, and turn consistency into real results. Start your streak today.

LOSE WEIGHT BY WINNING EVERY DAY

Most diet apps drown you in food databases and decimal points. Deficit Streak does one thing — and does it better than anything else: it keeps you in your calorie deficit, day after day, until the results show up.

Set your target. Check in once a day. Watch your streak grow. That's the whole game — and it's the only thing that actually moves the scale.

BUILD A STREAK YOU WON'T WANT TO BREAK One tap a day: hit your deficit, miss it, or take a rest day. Your streak grows with every win and becomes the daily motivation that keeps you consistent when willpower runs low. Earn streak freeze tokens to protect your progress on tough days.

SEE YOUR FAT LOSS BEFORE IT HAPPENS Our projection engine turns your banked calories into real numbers: estimated fat lost, a projected goal date, and a clear "on track" or "behind" status. No guessing — just a straight line to your goal.

KNOW EXACTLY WHERE YOU STAND

• Momentum score that reflects your last 30 days of consistency
• Cumulative deficit charts that show your progress climbing
• Weekly adherence rate and your strongest day of the week
• A color-coded calendar heatmap of every check-in

CELEBRATE THE MILESTONES Unlock achievements as you go — 7 days, 30 days, 100 days, thousands of calories banked. Every milestone is proof that you're building the habit that lasts.

WHY DEFICIT STREAK WORKS Weight loss isn't about one perfect day — it's about showing up consistently. By focusing purely on adherence instead of obsessive logging, Deficit Streak removes the friction that makes people quit, and replaces it with momentum that makes them keep going.
