LOSE WEIGHT BY WINNING EVERY DAY Most diet apps drown you in food databases and decimal points. Deficit Streak does one thing โ€” 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 โ€” 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 โ€” 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 โ€” 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 โ€” 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. FEATURES - Daily one-tap deficit check-in - Current and longest streak tracking - Streak freeze protection - Fat-loss projection and goal-date estimate - 30-day momentum score - Progress charts and weekly insights - Calendar heatmap view - Achievements and milestones - Goal setup in kg or lb - Clean, modern design with light and dark themes - Available in English, Spanish, French, Italian, German and Portuguese Deficit Streak is a motivation and habit-tracking tool to support your weight management journey.

About

NomCal

**Log a meal in seconds, not minutes.** NomCal is a calorie and macro tracker built around one idea: if logging is slow, you stop doing it. So there are four ways in, and you pick whichever is fastest right now. **Speak it.** Say "two scrambled eggs, a slice of sourdough and a flat white" and NomCal works out the calories, protein, carbs and fat. Correct anything it got wrong before you save. **Scan it.** Point the camera at a barcode and the product comes straight up, with full nutrition. Scanned products are cached, so repeat scans work even without a signal. **Search it.** Generic foods and branded products, with real serving sizes and unit switching โ€” grams to ounces, millilitres to cups or tablespoons. **Or just punch it in.** Quick Add takes calories and macros directly, with a built-in calculator that checks the numbers add up. **BUILT FOR REAL DAYS** โ€ข Your usual meals, one tap away โ€” NomCal learns the breakfasts and lunches you repeat and offers them back โ€ข Recipes with per-serving macros, so a batch of curry gets logged once and reused all week โ€ข Backdate anything: forgot yesterday? Swipe to the day and log it โ€ข Fibre, sugar and sodium alongside the big three โ€” free, not a paid tier โ€ข A health score on every food, so you can see quality, not just quantity **APPLE HEALTH, BOTH WAYS** Everything you log is written to Apple Health. Steps and active energy come back the other way, so your diary shows what you actually have left after moving. This is free and always will be โ€” no calorie tracker should charge you for your own health data. **SEE THE TREND, NOT THE DAY** Weight over weeks and months against your target, steps by day or by month, and a home screen widget with your calorie ring so you can check without opening anything. **GOALS THAT FIT YOU** Tell NomCal your height, weight, age and how active you are, and it works out daily calorie and macro targets โ€” or set your own and it stays out of the way. **PRIVACY** No ads. No data sold, ever. Your diary syncs privately to your account and nowhere else. Delete your account and everything on our servers goes with it โ€” two taps from Settings, no email to support required. **NOMCAL PREMIUM** Voice logging and your usual-meal suggestions are Premium. Everything else โ€” barcode scanning, food search, recipes, Apple Health, micronutrients, the widget โ€” is free, with no entry limits. New users get 3 free voice logs a month to try it properly. โ€ข Monthly โ€” $4.99/month โ€ข Annual โ€” $34.99/year, with a 7-day free trial Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple Account settings.
