"Ugh, we're out of shampoo again..." Sound familiar? Say goodbye to forgotten essentials. Kaidoki automatically tracks and reminds you when it's time to restock your everyday household items. It learns your purchase cycles and notifies you at just the right time. Easy Setup Choose from over 100 pre-built templates — shampoo, detergent, toothbrushes, plastic wrap, and more, all organized by category. You can also add custom items anytime. Status at a Glance Each item shows one of four color-coded statuses: "All Good," "Running Low," "Time to Buy," and "Overdue." Progress bars visualize how far along each cycle you are. Just open the home screen to instantly see what needs restocking today. Never Forget to Restock Get reminders 7 days, 3 days, and the day before an item is due. Choose your preferred channel — push notifications or LINE messages. You can even pick the time of day (morning, noon, or evening) to match your shopping routine. Share with Family & Roommates Use Groups to co-manage items with family or housemates. Just share an invite code to get started — when someone adds an item, everyone gets notified. No more "Who's picking that up?" back-and-forth. One-Tap "Got It" Logging Tap "Got It" from a notification or the item detail screen to log a purchase instantly. Your next restock date updates automatically. LINE Integration Sign in with LINE, and with the Pro plan, get notifications delivered straight to your LINE chat. Everything stays in the app you already use every day — no need to remember to open another app. Perfect for: - People who frequently forget to restock household essentials - Families who share shopping responsibilities - Anyone who struggles to keep track of supplies - People who want to cut down on unnecessary purchases - Housemates who need to manage shared supplies
