Sugar Counter

Read full description

Sugar Counter A simple app for tracking your daily refined sugar intake in grams. All local. No cloud. No ads. Free. Made for anyone with a modern iOS device. Created by an MD/PhD focused on vascular health. Track refined and added sugars from packaging quickly—without fumbling with barcode scanners. Fast data entry with clear visuals serves as a daily reminder to reduce refined sugar intake. The Science: Why Sugar Matters The modern diet is saturated with "hidden" sugars—specifically high-fructose corn syrup and sucrose—that bypass normal satiety signals and place an immense metabolic load on the liver. Unlike glucose, which can be used by every cell in the body, fructose is primarily processed in the liver, where high doses can trigger lipogenesis (fat production), insulin resistance, and chronic inflammation. Research highlights the urgency: Metabolic Syndrome: Excessive refined sugar intake is a primary driver of metabolic syndrome, independent of total caloric intake (Lustig et al., 2012, Nature). Cardiovascular Risk: High-sugar diets are significantly associated with increased cardiovascular disease mortality (Yang et al., 2014, JAMA Internal Medicine). The 5% Rule: The WHO strongly recommends reducing free sugar intake to less than 10%—and ideally 5%—of total energy intake to prevent non-communicable diseases. Sugar Counter helps you stay within these evidence-based limits - simple fast app, all local data, simple CSV export.

About

Fasty

Fasty is the simplest way to track intermittent fasting — 16:8, 18:6, 20:4, OMAD, or custom. One tap to start. Live Activities keep your progress on the Lock Screen without opening the app. Pick a plan, tap Start, and let Fasty take care of the rest. Your fasting timer lives where you actually look: the Home Screen widget, the Lock Screen Live Activity, and the Dynamic Island, so you always know how long you have left without opening the app. WHY FASTY - Quiet by design. No streak shaming, no animated pressure, no push spam. - Local-first. Your data stays on your device. No account. No backend. No tracking. - Just enough features. A timer, proven plans, history, widgets, and Live Activities. PLANS INCLUDED - 16:8: the most popular daily window. - 18:6: a tighter eating window for experienced fasters. - 20:4: the Warrior style, one main meal. - 24h: a full-day fast for an occasional reset. WIDGETS & LIVE ACTIVITY Add the Fasty widget to your Home Screen or Lock Screen and your remaining time updates automatically. When you start a fast, a Live Activity appears in the Dynamic Island and on the Lock Screen so progress is one glance away. NOTIFICATIONS Fasty sends a single local notification when your fasting window completes. No marketing pushes, no streak nags. You can turn notifications off any time in iOS Settings. PRIVACY Fasty does not collect data. There is no sign-in. Your fasting history lives only on your device and is shared with the widget through Apple App Groups, never sent to a server. MEDICAL DISCLAIMER Fasty is a habit-tracking timer, not medical software. Fasting is not appropriate for everyone. If you are pregnant, breastfeeding, under 18, have a history of eating disorders, diabetes, any chronic condition, or are taking long-term medication, consult a qualified healthcare provider before starting any fasting regimen.
