Track what you eat, how long you fast, and how your meals affect your glucose — all without an account, cloud sync, or ads. Everything stays on your iPhone. LOG FOOD IN SECONDS Search 500,000+ foods from the USDA database — stored entirely on-device, no internet needed. Scan a barcode and get instant nutrition data from the Open Food Facts database. Snap a photo of your meal and let on-device AI identify the food and fill in the macros. Or just type it in manually. Every entry shows calories, protein, carbohydrates, and fat. Set your daily targets and watch your rings fill as you log. FASTING TRACKER — PREMIUM MacroFast automatically calculates your fasting window from the last meal you logged. No timers to start or stop. See your current fast length, your fasting zone, and your full fasting history at a glance. Black coffee, water, and zero-calorie items can be marked to exclude from your fast. GLUCOSE INSIGHTS — PREMIUM Connect a continuous glucose monitor via Apple Health and see how your meals affect your blood sugar. MacroFast draws a 24-hour, 3-day, or 7-day trend chart directly from your Apple Health data — on-device, never uploaded. Set a personal in-range goal and track your time within it. Supports both mg/dL and mmol/L. Units are detected automatically from your Apple Health settings. Note: Glucose Insights is a personal wellness tool. It is not a medical device and does not provide medical advice. Always consult your healthcare provider for clinical guidance. HISTORY & TRENDS — PREMIUM A full calendar view of every day you've logged. Tap any date to see your totals, meal breakdown, and fasting window for that day. Weekly and monthly charts show your calorie and macro trends over time. APPLE HEALTH INTEGRATION MacroFast can optionally write your logged meals — calories, protein, carbohydrates, and fat — to Apple Health so they appear alongside your other health data. This is off by default and can be toggled in Goals at any time. PRIVACY BY DESIGN No account. No sign-in. No cloud. No ads. No tracking. All your food entries, macro history, fasting records, and glucose data stay on your device in Apple's encrypted on-device storage. Barcode lookups are anonymous. The USDA food database is bundled in the app — it never phones home. PREMIUM SUBSCRIPTION MacroFast Premium unlocks: · Fasting Tracker with zone history · Glucose Insights with trend charts · Full History calendar · Weekly and monthly macro charts Basic calorie and macro logging is always free, forever. MacroFast is not a medical device. Calorie targets, fasting zones, and glucose goal ranges are personal wellness goals you configure — not clinical recommendations. Consult a qualified healthcare provider before making changes to your diet or when interpreting health data.

Locs take years. Locy keeps the whole arc in one calm place: where you are, what your hair needs this week, and how far you have already come. A JOURNEY THAT SPANS YEARS Photograph your locs over time and watch the timeline fill in. Locy counts your loc age from the day you started, marks the stage you are in, and puts any two photos side by side so months of slow change become visible at once. ROUTINES THAT FIT YOUR HAIR Set your own rhythm for misting, moisturising, oiling, washing and retwisting. Locy reminds you on the days that matter and keeps a streak of the care you actually did, not the care you meant to do. Log care whenever it fits your day, review your completion history, and see your care reflected on Today. Reminders stay on your device. KNOW WHAT IS IN THE BOTTLE Photograph the front of a product and Locy reads the label, looks up the formula, and scores it against your porosity, stage and routine. Every flagged ingredient is explained and linked to published sources, including the EU CosIng annexes and ECHA substance records, so you can see why a score is what it is instead of taking a number on faith. THE LOC LIBRARY A field guide to the whole journey: washing, moisture, retwisting, scalp, choosing products, troubleshooting, and keeping locs healthy for the long run. Filtered to your stage, written to be read when you need it. ASK YOUR COMPANION A companion that already knows your stage, your routine and what you have scanned. Ask about wash rhythm, retwist timing, buildup, or what to use instead of something that is not working. It is an AI, so it can be wrong, and it will point you to a dermatologist or loctician rather than guess about anything medical. WHAT IS FREE Your full journey, routines, reminders and the entire Loc Library, plus four product scans and ten companion messages. LOCY PLUS An auto-renewing subscription that unlocks unlimited product scans, unlimited companion messages, and your daily For you lineup: products matched to your locs, fresh every day. The full product catalogue is free to browse. Annual, monthly, and weekly plans are available. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and you can manage or cancel it any time in your device Subscription settings. PRIVACY Your photos are yours. Journey photos and videos stay on your iPhone by default, with optional Locy backup. We do not sell your photos or use them to train our own models. Scanned product photos are read by an AI processor to identify the label. Sending a photo to the companion for analysis asks your permission first. Optional tracking permission lets TikTok measure Locy installs and opens using device identifiers and technical app information. Your Locy photos, conversations, profile, purchases and subscription information are not shared with TikTok. You can decline or revoke tracking permission without losing access to Locy.
