If you're vegan or vegetarian, pregnant or breastfeeding use this app to avoid the effects of zinc deficiency. Zinc is critical for a healthy immune system, wound healing, cell division, growth, and metabolism, and protects against many diseases including cardiovascular disease, diabetes, arthritis, skin diseases, dementia and Parkinson's disease. Zinc deficiency in pregnancy and childhood impairs growth and development. Deficiency in older adults can impair wound healing and brain and mental health. Set your target daily zinc intake based on guidance provided in the app and your preferences for weights of food (g or oz). Record food and beverage consumption using dictation, search, or by favoriting foods, and using the serving sizes provided, which can be changed at any time. Tap the notepad to add notes. Compare the zinc content of different foods by tapping the Compare button on the "Foods" screen. Monitor daily and long-term progress, export data to share with healthcare providers, synchronize data with other First Line Medical Communications Ltd nutrient counter apps, and share data with Apple's HealthKit. Add your own foods and recipes and change serving sizes to personalize the app's 400-item database for you. All food and beverage popups indicate whether the item is a plant, good prebiotic, probiotic or ultra-processed food (UPF) to inform a healthy diet and whether they are high or low FODMAP per serving where data are available to support people with irritable bowel syndrome (IBS). Useful lists show zinc content of foods per 1oz or 100g and serving, which can be toggled from high to low & low to high. Also useful UPF, unprocessed plant, prebiotic, probiotic, high & low FODMAP food lists.

Daylight helps you become more aware of your time in daylight, so you can build routines that bring balance and energy to your day. In northern countries, especially during darker months, it’s easy to spend most of the day indoors. Daylight helps you notice how much light you actually get and reminds you to go outside when it matters most. With Daylight you can: • See your daily and weekly daylight minutes — simple, visual, and motivating. • Set your own daylight goal — choose how much time you’d like to spend outside. • Get friendly reminders — a gentle nudge if you haven’t reached your goal yet. • Sync automatically with Apple Watch — or track manually, no Watch required. • Build awareness — small moments in daylight can make a big difference in how you feel. Daylight integrates with Apple Health to read and write your daylight data. All information stays private and secure on your device. Notice your light. Find your rhythm. Feel more balanced.
