The Plan tab is where you decide what you are cooking and when. It has two views that work side by side, so you can plan loosely on a calendar or tightly inside a named plan, whichever fits the week.
The calendar view shows a month you can add meals to on any date. Tap a day, add a recipe, and it sits on that date. This is the flexible option: drop dinner on Thursday, add a weekend lunch, fill in a few days and leave the rest open. There is no start or end, just a running month you build as you go.
The Plans view holds named plans, each with a start date and an end date. That makes it easy to run a "week of" plan, like a Thanksgiving spread or a batch of lunches, and to keep several plans going at once without them bleeding together. Give a plan a name, set the dates, and add meals inside it.
Use the calendar when you are thinking day by day. Use a plan when you want a defined block of time you can name, revisit, and turn into a grocery list.
Adding a meal works the same in both views:
The meal shows up on that day under the time you picked, so a single date can hold breakfast, lunch, dinner, and a snack without crowding.
Plans change. You can remove any meal individually without touching the rest of the day or the plan around it. Take one dinner off Wednesday and everything else stays put.
Once a plan has meals in it, you do not have to copy ingredients by hand. From the Plans view you can build a grocery list straight from the recipes you added, and Tradish sums the quantities and clears out duplicates for you. See Building a grocery list from your plan.
To change which meal times you see, or rename them, see Meal times.
