SOL vs StayFasted

SOL (솔) — Korean for Pine Tree. Like the pine that endures through every season, SOL stands with you through every fast. WHAT MAKES SOL DIFFERENT Most fasting apps just show a timer. SOL shows you what's actually happening inside your body — in real time. As you fast, SOL guides you through each biological phase: Fed State → Insulin Dropping → Fat Burning → Ketosis → Autophagy → Deep Autophagy → Growth Hormone Surge → Immune Reset FEATURES • Beautiful minimal timer with progress ring • Real-time body phase updates with scientific sources • Full body timeline — see all 8 phases and your progress • Tap any phase for in-depth science and PubMed sources • Smart notifications at each milestone • Stats dashboard — track your fasting journey • Background timer — keeps running when you close the app • Light & dark mode with handcrafted watercolor textures • Home screen widget • Community pulse — you're not fasting alone • Share your results with a beautiful card FASTING GOALS Choose from 16h, 18h, 20h, 24h, 36h, 48h, 72h, or go Open with no time limit. Hit your goal? Extend to the next level. DESIGNED WITH INTENTION SOL is inspired by the simplicity of nature. No clutter, no ads, no unnecessary features. Just you, your fast, and the knowledge of what your body is doing. All body phase information is based on peer-reviewed scientific research with direct links to PubMed sources. Begin your fast. Know your body. Grow like the pine.

StayFasted is the fasting app that actually keeps you going. Most fasts don't end because of the plan. They end in one hard half hour. StayFasted is built around that half hour: a timer you can trust, a guide to what to expect, and a check-in that answers back. A TIMER FOR EVERY FAST 16:8 · 18:6 · 20:4 · One Meal a Day · 36h · 48h · 72h. One button starts it. Forgot to start? Move the start time in seconds. Your fast also shows on your Lock Screen, in the Dynamic Island, in widgets and on Apple Watch. KNOW WHAT TO EXPECT, HOUR BY HOUR For each part of a fast: what is generally understood, what people often feel, and what tends to help. Timing differs from person to person. General information, not medical advice. CHECK IN WHEN IT GETS HARD Mood, hunger and energy in a few taps. With Pro, an AI replies to what you wrote, how you feel and why you started. It runs on your iPhone, and it never pushes you to carry on. BREATHE Short breathing sessions for the moment a craving arrives, and a guided deep rest for when you need to lie down for ten minutes. On your phone and on your wrist. FLUIDS AND ELECTROLYTES Log water, coffee and tea in one tap. See whether you are keeping an even pace through the day. Electrolyte reminders for longer fasts. END IT WELL Stop whenever you choose. A refeed guide walks you back to food gently, from liquids to normal meals. SEE YOUR PATTERNS Insights in plain words from your own data, always honest about how much data they are based on. Progress photos on a timeline. A monthly report you can share with your doctor or coach. APPLE WATCH See your fast, start or end it, log water, check in and breathe. APPLE HEALTH Optional. Reads weight, steps, sleep, resting heart rate and active energy. Saves weight, water and mindful minutes. You choose what to share. YOUR FASTING DATA STAYS ON YOUR PHONE No account and no sign-up.
