Decide what's for dinner once, and let SimDin handle the rest. SimDin builds a personalized meal plan around how you actually eat, turns it into a single consolidated grocery list, and if you shop at Kroger sends that list straight to your cart. No more staring into the fridge at 6pm. PLAN A WEEK IN SECONDS Tell SimDin your dietary preferences, allergies, cuisines you love, and how much time you have to cook. It generates a plan starting tomorrow, for as many meals as you want. MAKE IT YOURS A generated plan is a starting point, not a verdict. Tap any meal to regenerate just that one, swap it for a recipe you search, or lock it so it survives when you regenerate the rest of the week. ONE SMART GROCERY LIST Every ingredient across every meal is combined into one list, with quantities added up properly and items grouped by aisle. Export it as a PDF, or keep it in the app. SHOP WITHOUT RETYPING Connect a Kroger account and SimDin matches your list to real products at your store, with prices. Approve the matches and send everything to your Kroger cart in one tap. You finish checkout on Kroger. SCAN YOUR PANTRY AND YOUR COOKBOOK Point your camera at a shelf to add what you already have, so SimDin plans around it. Snap a photo of a recipe from a cookbook or a card and SimDin reads it in and saves it. BUILT FOR HOUSEHOLDS On Family, add up to 6 household members with their own dietary profiles, so one plan works for everyone at the table. ALSO INCLUDED - Recipe search and favorites - Nutrition information for every meal, including protein, carbs, fat, and fiber - Recurring meals for the nights that never change - Notifications when your plan and list are ready SUBSCRIPTIONS SimDin offers auto-renewing monthly subscriptions with a 14-day free trial: - SimDin Starter — $3.00/month: up to 4 plans per month, grocery lists, PDF export, recipe search - SimDin Pro — $5.00/month: unlimited plans, Kroger integration, nutrition tracking - SimDin Family — $7.00/month: everything in Pro, up to 6 household members with per-member dietary profiles Payment is charged to your Apple Account at confirmation of purchase.
