A phone reminder is easy to swipe away. A rubber band on the coffee maker is not. Most supplement apps send one more notification and hope it sticks. Oing puts the habit somewhere you cannot swipe away, in the room where your hand already goes. It is a daily habit tracker for vitamins and supplements, built on one idea: you do not remember a habit, you run into it. HOW IT WORKS 1. Choose a moment you already have. Morning coffee. Brushing your teeth. 2. Leave a mark there. A rubber band, a sticky note, the bottle itself. 3. Tap once when it is done. That is the whole thing. You see one card a day. Not a list of chores. WHAT YOU CAN KEEP Vitamin D, omega-3, magnesium, probiotics, or whatever is already on your shelf. Add a product by photo or by name, and your routine stays in one place. WITH THE PEOPLE YOU CARE ABOUT Habits hold better when someone you trust can see them. Connect with a few people, see whether today is done, and send a small nudge if it is not. You decide what shows, and private stays private. WHAT WE DO NOT DO No streaks to break. A missed day does not undo anything. No shame for a day off. No pinging you at midnight. No selling your health data. MORE ONCE YOU ARE IN Reminders that learn when you actually take them, not when you said you would. Aing reads your whole shelf together and tells you what is worth knowing. A Formation Letter that shows how the habit is settling, week by week. Start free. Care together. Oing is for adults 18 and over and offers general wellness information, not medical advice. Talk to a healthcare provider before changing any supplement routine.
