Start with one thing you want to stop carrying in your head. A task you keep remembering at the wrong moment, a grocery list, or a date you want to make time for. You do not need to fill every part of Tiptoe before it becomes useful.
Create your own account, confirm that you are 18 or older, and set up your shared space. Choose your timezone so reminders make sense where you are. Add household details if you want help finding useful Ownership Cards.
In Lists, choose Create a meal plan for seven days you can both edit. Enter a meal and its ingredients for each day, and your changes save when you leave the field. Groceries from this plan copies the ingredients you typed to your grocery list. It does not suggest recipes or work out ingredients for you.
Invite your partner when you are ready. They join with their own account, and one subscription covers you both. You can use tasks and lists before they arrive.
Finally, pick a weekly check-in day and time. Start small: one appreciation, one thing to plan, and one topic worth talking about. You can adjust your setup as life changes.
