LockFast vs Sipling

LockFast is the fasting timer built for people who take performance seriously. No meal plans. No calorie counting. No social feeds. Just a precision timer that tracks your metabolic state in real time and tells you exactly where you are in your fast. REAL-TIME METABOLIC ZONES LockFast tracks four metabolic phases as you fast: • Fed — digesting and storing energy (0-4h) • Fat Burning — glycogen depleting, fat mobilizing (4-12h) • Ketosis — producing ketones for fuel (12-16h) • Autophagy — cellular cleanup and renewal (16h+) Watch your progress ring fill as you move through each zone. A countdown shows exactly when you'll hit the next phase. FOUR PROVEN PROTOCOLS Choose the fasting window that fits your life: • 16:8 — the gold standard for beginners • 18:6 — intermediate, deeper fat burning • 20:4 — advanced, extended ketosis • OMAD — one meal a day, maximum autophagy Each protocol includes a full description of what to expect, example timing, and who it's best for. WATER TRACKING Stay hydrated during your fast with built-in water tracking. Quick-add buttons for 250mL, 500mL, and 750mL. Visual progress ring and daily goal tracking. Your body needs water to metabolize fat — LockFast makes sure you don't forget. EATING WINDOW TIMER When your fast ends, LockFast automatically starts an eating window countdown so you know exactly when to begin your next fast. No guesswork, no math. STREAKS & STATS Track your current streak, longest streak, total fasted hours, and average fast duration. A weekly bar chart shows your last 7 days at a glance — the visual accountability that keeps you consistent. SESSION SUMMARIES Every completed fast gets a summary card showing your duration, peak metabolic zone reached, and current streak. The moment of accomplishment that builds the habit. BUILT FOR FOCUS LockFast doesn't try to be a nutrition app, a workout tracker, or a social network. It does one thing — tracks your fast — and does it exceptionally well. Dark interface. Clean design. Zero distractions. Start your first fast in under 60 seconds. Terms of Use (EULA): https://lockfast.io/#terms

Sipling turns drinking water into something you can see. Every glass waters a sapling. Hit your daily goal and it becomes a tree in your own forest. Miss a day? Nothing dies. Your sapling simply waits for you. A FOREST THAT NEVER WITHERS Most habit apps punish you. Sipling doesn't. There is no guilt, no dying plant, no broken heart icon. A day you missed is just a young sapling, still standing. A GOAL THAT FITS YOU Your daily target is calculated from your weight, sex, age and activity level, based on the European Food Safety Authority's reference values for water from drinks. You can always adjust it yourself. NOT EVERYTHING COUNTS THE SAME Tea, coffee, milk, juice and soda are counted with their own hydration factors — 250 ml of coffee is not 250 ml of water. Alcohol counts against you, honestly. REMINDERS THAT ACTUALLY ARRIVE Sipling reminds you between your waking hours, at the interval you choose, and goes quiet once you reach your goal. YOUR DATA STAYS ON YOUR PHONE Sipling has no server and no account. It goes online for only two things: ads, and anonymous crash and usage measurement — you can turn the measurement off in Settings. Everything you enter lives on your device and nowhere else. You can erase all of it in one tap. EIGHT TREE SPECIES, TEN ACHIEVEMENTS Oak, pine, sakura, maple, acacia, olive and more. Unlock them by keeping streaks and growing trees — never by paying for the basics. SIPLING PRO Pro removes ads and unlocks seasonal forest themes and a few cosmetic trees. Tracking, goals, statistics, reminders and your forest are free, forever. We will never put a paywall in front of the things that matter. — No interstitial ads between screens. — No ads during celebrations. — No account, no sign-up, no tracking. Drink water. Grow a forest. Be kind to yourself.
