About this app
iendly calorie deficit calculator, food tracker and on-device AI coach in one. Enter your details, choose a goal, and get a personalized daily calorie target in seconds — then log meals, workouts, water and intermittent fasting to stay on track. Meet Sprig, your cozy companion who cheers you on and chats with you privately, 100% on your phone. No account required; your stats, plan and diary stay on your device.
Whether you want to lose weight, cut body fat, or just understand your numbers, CutCal turns the science of a calorie deficit into one clear daily target — and the simple tools to actually hit it.
WHY A CALORIE DEFICIT?
Weight loss comes down to one principle: eat fewer calories than you burn. CutCal works out how many calories you burn each day (your maintenance calories, or TDEE) and subtracts a safe deficit, so you lose weight at a steady, sustainable pace.
YOUR DAILY TARGET
• Calorie deficit calculator — your exact daily calorie target for weight loss
• Maintenance calories (TDEE) from the trusted Mifflin–St Jeor equation (Katch–McArdle when you add body-fat %)
• Pick your pace — 0.25, 0.5 or 0.75 kg (0.5–1.5 lb) per week
• Choose a macro split — balanced, high-protein or low-carb
• Estimated goal date so you know exactly when you'll get there
• Safe calorie minimums so your target never drops too low
LOG FOOD THE EASY WAY
• Scan barcodes for instant nutrition (Open Food Facts)
• Search foods by name, or quick-add calories offline
• Tracks calories and macros (protein, carbs, fat) — fiber & sugar with Pro
• Favorites, meal templates and copy-yesterday for one-tap re-logging
• Water tracking plus a clean Home dashboard calorie ring
TRACK ACTIVITY & NET CALORIES
• Log workouts — walking, running, cycling, swimming, weights, HIIT, yoga and more (MET-based)
• Keep activity calories separate, or add them back to your daily budget
• Net intake updates live: food in, exercise out
INTERMITTENT FASTING
• Fasting tracker — 16:8, 18:6, 20:4, OMAD, 24h or custom windows
• Manual or Auto mode (logging food can end your fast and start the eating window)
• Live countdown, fasting streaks and completion reminders
MEET SPRIG — YOUR ON-DEVICE AI COACH
• Chat for meal ideas, motivation and plan explanations
• Voice input — talk instead of type
• Ask Sprig to log food, water or a fast — just confirm
• Runs 100% on-device — nothing you say leaves your phone
• Adaptive coaching learns your real maintenance from weigh-ins and flags plateaus
STAY MOTIVATED
• Weekly weigh-ins with a weight-trend chart and progress streaks
• Achievements, progress photos and a shareable weekly recap
• Optional daily log and weekly check-in reminders
• Calorie cycling — more on training days, less on rest days, same weekly average
SIMPLE BY DESIGN
• No account, no sign-up, no email, no ads
• Optional one-time CutCal Pro unlock — no subscription, ever
• Metric and imperial (kg/lb, cm/ft) · light and dark mode · 10 languages
• Share your plan; back up or restore your data any time
YOUR DATA STAYS YOURS
Your stats, goals, weigh-ins and food/activity log stay on your device — no account required. Barcode and food-name lookups go to Open Food Facts for nutrition info; optional anonymous usage events help improve the app. Sprig chat stays fully on-device. Reset or uninstall any time to erase your diary.
WHO IT'S FOR
Anyone starting a cut, diet or weight-loss plan who wants a reliable daily calorie goal and a simple, kind way to follow it — without the bloat of a heavyweight calorie counter.
