FatFlow
Read full descriptionHide full description
Most people know what they ate. Far fewer understand what may be happening in the hours afterward. After eating, insulin rises to help the body use and store incoming energy, while reducing the release of stored fat. As time passes without more food, insulin generally falls and the body gradually shifts toward using more stored energy. FatFlow makes this invisible process easier to understand. Log meals, drinks and activity in seconds. FatFlow then provides an educational estimate of whether your body is likely processing recent food, shifting fuel sources, or spending more time in a fat-burning state. Use FatFlow to: • See your current estimated metabolic state • Understand how long it may take to return to fat burning • Review daily and weekly patterns • Log meals, drinks and activity quickly • Set recurring entries and reminders • Create optional backups of your history FatFlow is designed for awareness, not judgment. It does not count calories, prescribe a diet or tell you when to eat. It helps you see how timing may shape your day so you can make more informed choices. Privacy first: • Your meal, drink and activity history stays on your device • No account is required • No ads • No subscriptions • 100% free Important: FatFlow provides educational estimates, not direct measurements. Actual responses vary based on meal size and composition, activity, metabolism, sleep, medications and health conditions. FatFlow is not a medical device and does not provide medical advice, diagnosis or treatment.

Everyone has a vision. Most people scroll past it. ARC helps you stop scrolling past yours. You pick the apps that pull you in. ARC locks them until you’ve proven today’s three core quests. Then they open again. Yes, we know how that sounds: an app against too many apps. That’s exactly why ARC is happy when you close it. HOW IT WORKS You pick the apps that eat your time. ARC locks them with Apple’s Screen Time: a real lock, not a reminder you swipe away. Every task you finish earns cookies. Cookies buy you free minutes. THREE CORE QUESTS A DAY After a few questions, ARC builds your path: 180 days, three core quests every day that fit your goal. Plus your own to-dos. PROVE IT, DON’T TICK IT A checkbox is free. In ARC you show what you did: - a photo, checked by AI - the camera counts your push-ups and squats - a focus timer that holds you to it - runs from Apple Health count by themselves YOUR WOLF Your wolf grows a little every day, from pup on day 1 to day 180. Yes, he’s cute. You’re still doing the push-ups. WITH PEOPLE LIKE YOU - Weekly leagues - Friends by code or username - Challenges: kilometres, reps, focus minutes or less screen time - Chat with reporting and blocking RUNS FROM APPLE HEALTH Run with Apple Fitness, Strava, Nike or adidas. With your permission, ARC reads your running workouts from Apple Health so kilometre challenges and running tasks count automatically. ARC reads nothing else and writes nothing to Apple Health. ALSO INSIDE - Focus mode and sleep mode - Widgets and a Live Activity - For iPhone and iPad, in English and German WHO IT’S FOR For everyone with a plan who notices in the evening that three hours are gone again. Who installed five blocker apps and deleted them all after two days. Who don’t want a lecture, but a reason. Become anyone. ARC PRO ARC Pro is an auto-renewing subscription, weekly or yearly. New subscribers get a trial week at no cost. The price is shown in your local currency before you subscribe. Payment is charged to your Apple account. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. You can cancel anytime in your Apple account’s subscription settings.
