Remember what needs doing again – without keeping it all in your head. 99 Reminders helps you stay on top of recurring chores, habits, and personal routines. See when you last did something, know what’s due next, and get a reminder when it’s time. Change the bedsheets. Water the plants. Replace a filter. Book a haircut. Keep track of the little things that are easy to forget between one time and the next. REPEAT FROM WHEN YOU FINISH Some tasks make more sense on an interval than on a fixed calendar date. Want to clean something every two weeks? Complete it today, and the next cycle starts today – even if you finished later than planned. Choose an interval in days, weeks, or months, or set the next due date yourself. SEE YOUR ROUTINES AT A GLANCE Each task has a battery that gradually drains as its due date approaches. A full battery means you’ve recently taken care of it. A low battery shows what needs attention next. Finish the task, recharge its battery, and start the next cycle. MAKE ROOM FOR EVERYDAY LIFE • Flexible reminders – choose notifications on the due date or days in advance, at a time that suits you. • Batteries on hold – stop selected countdowns and their reminders while you’re away or taking a break. Set start and resume dates, manage several batteries together, and keep your history. • Home Screen and Lock Screen widgets – keep your routines in sight without opening the app. • Custom categories – organize chores, self-care, home maintenance, and more. • Completion history and notes – remember when you last did something and save useful details for next time. • Saved ideas – keep books to read, places to visit, or other ideas alongside each routine. Completed ideas become part of its history. • Visual progress and streaks – see how consistently you’ve kept your routines going. • Ready-made templates – start with familiar tasks or create your own. • Help finding new routines – get suggestions from an AI assistant you already use, such as ChatGPT or Claude, then choose which routines to add to 99 Reminders. From daily habits to jobs that only come around every few months, give each routine its own rhythm. START SMALL, ADD MORE WHEN YOU NEED TO Track up to five routines for free. Upgrade to Premium for unlimited routines. Start with one thing you’re tired of forgetting. Questions or ideas? Contact us at contact@99reminders.com.
