Know exactly how many days of each supplement you have left, without logging a single dose by hand. Re:Stock tracks the real containers on your shelf: the bottle of 120 capsules, the tub of creatine, the dropper of vitamin D. You set up how you take each one just once, and Re:Stock counts it down for you, every day, on its own. WHAT MAKES IT DIFFERENT • Real containers, real numbers Capsules, tablets, softgels, gummies, powders, liquids, drops, and sprays - track what's actually in the bottle and see a plain "12 days left," not a vague bar or percentage. • It runs itself Build your stacks and daily schedules once. Re:Stock subtracts each serving as the day goes by, so your counts stay accurate with no check-ins and no manual logging. • Made for real life Skip a day, take an extra, pause for a week, or switch to a different brand halfway through a bottle. Nothing breaks, and your numbers stay honest. • See what needs you, skip what doesn't Your dashboard puts what's running low up top and lets the rest wait quietly. No clutter, no endless list to scroll. • As-needed doses, counted too Log the occasional as-needed (PRN) supplement in a tap, and it comes straight off your inventory. • Reorder at the right time When something gets low, Re:Stock turns it into a simple restock list, so you buy the right things before you run out instead of after. • Private and in sync Your data syncs across your devices through iCloud. No ads, no social feed, no busywork. FREE AND PREMIUM The free version tracks up to 5 supplements and 3 stacks, with the same automatic countdown. Premium removes the caps and adds calendar reminder sync, adaptive forecasting that learns from how you actually take things, stack cost analytics, and adherence nudges. Subscribe monthly or yearly, or buy lifetime access once. Set it up once and stop doing supplement math in your head. Download Re:Stock and always know what you have, what's low, and what to buy next. Privacy Policy: https://restockapp.app/privacy/ Terms of Use: https://restockapp.app/terms/
