SipSync is the hydration tracker that respects your privacy as much as your health goals. Everything happens on your device โ€” no account needed, no data ever sent to a server, no ads, no nonsense. TRACK YOUR DAILY HYDRATION Log water intake in seconds with large, visual presets. A beautiful animated wave fills your progress ring as you drink โ€” satisfying, glanceable, and built for busy people who don't want to think twice about it. STREAKS THAT ACTUALLY STICK Your daily streak grows visually โ€” a small flame on day 1 becomes a pulsing glow by day 7, and turns gold after 30 days. Miss a day? Your weekly shield has you covered. One free pass per week, automatically applied where it helps your streak the most. SMART, SILENT REMINDERS SipSync schedules gentle reminders that adapt to your progress. Falling behind by afternoon? They arrive more often. Already hit your goal? They back off. All scheduled locally โ€” no server involved, ever. YOUR HISTORY AT A GLANCE Swipe back through past weeks with a clean bar chart showing daily totals, a goal line, and a week summary that tells you exactly how consistent you've been. See your best streak, weekly goals hit, and a pip row showing which days you nailed it. SCAN YOUR CUP SIZE Point the camera at your cup or glass and SipSync estimates its volume for faster logging. All processing happens on your device โ€” no photos are ever saved, uploaded, or shared. EXPORT YOUR DATA Export your full hydration log as a CSV file at any time. Your data is yours โ€” take it wherever you want. BUILT FOR PRIVACY-FIRST USERS - 100% offline โ€” works without any internet connection - No account or sign-up required - No third-party analytics or tracking libraries - No ads, ever - GDPR-friendly by design - Made in EU SipSync is for busy students, professionals, and anyone who wants to build a real hydration habit without handing their data to yet another app. Simple. Private. Yours.

About

BulkUp

BulkUp is the protein tracker built for people trying to gain weight and build muscle, not fat. Every other nutrition app was designed for weight loss. The defaults are wrong. The language is wrong. The success states are wrong. If you're a hardgainer, someone in a bulk phase, or just someone trying to eat more and build muscle, you've been using the wrong app. BulkUp is built for you. TRACK YOUR BULK, NOT YOUR DIET Set your daily calorie surplus and protein goal based on your body stats and gain rate. Log meals in one tap using your personal preset library. Watch your dual progress rings fill up: one for calories, one for protein, and know instantly whether you're on track to gain today. No calorie deficits. No weight loss streaks. Just: did you eat enough to grow? KNOW EXACTLY WHEN YOU'LL GET THERE BulkUp forecasts your goal weight date dynamically. As you log real weigh-ins, the app recalculates your actual gain rate and updates your estimated arrival date automatically. Whether you're on pace, ahead, or behind โ€” you'll always know where you stand. Compare all three bulk modes side by side: Lean, Balanced, and Aggressive โ€” with estimated dates and fat gain risk for each. BUILT AROUND HOW YOU ACTUALLY EAT No food database to search. No barcode scanner to fumble with. Just a personal library of meals you actually eat, organised by your own meal timings. Tap once to log. Done. Add manual meals when needed with calories, protein, carbs and fat (the macros). TRACK WHAT MATTERS WHEN BULKING - Calorie surplus vs. your personalised calorie target - Daily protein goal - Weekly weight trend with various charts and analytics - Measure body fat percentage with multiple methods - Muscle vs. fat gain - body composition chart over time - Macro breakdown: protein, carbs, and fat percentages - Creatine streak - never miss a day CONNECTS TO APPLE HEALTH Link Apple Health to replace estimated calorie burn with your real active and resting energy data. Your calorie target updates daily based on what you actually burned, not a static formula. PREMIUM Upgrade to premium for unlimited preset meals, full weight trend charts, dynamic goal forecasting, body composition tracking, macro breakdown charts, Apple Health sync, and a home screen widget. $3.99/month, $29.99/year, or $59.99 for lifetime. BulkUp is built by an indie developer who lifts. No subscriptions you don't need. No weight loss defaults. Just a focused tool to help you eat more, gain well, and hit your goal weight.
