How it works
Built around your week,
not a recipe book.
Most meal planners dump random recipes at you. Rattatool builds a coherent weekly structure — calibrated to your body, your goals, and what you can actually cook.
Set your profile
Height, weight, goal, cooking skill. The plan adapts to you — not the other way around.
Generate your week
One tap. Three meals a day, seven days. Portions scaled to your calorie targets.
Shop and cook
A consolidated grocery list. Recipes sorted by day. Mark meals as done as you go.
Precision nutrition
Calories and macros
tailored to your body.
Mifflin-St Jeor BMR, activity-level TDEE, goal-based adjustments. Portions are scaled per meal so your daily totals actually land where they should — not whatever the recipe happens to yield.
Lose weight
−500 kcal deficit
Build muscle
+350 kcal surplus
Stay fit
Maintenance TDEE
Grocery logic
One list. No duplicates.
Ingredients from all 21 meals are consolidated and quantity-adjusted. Walk into the store with a clean list, not seven recipe tabs.
Beginner track
Starts simple. Builds skill.
Week 1 is no-cook and one-pan meals. By week 6, you're building full dinners. The system scales difficulty so you don't burn out.
Not another recipe app.
There are thousands of recipe apps. Rattatool isn't one. It's a structured weekly planner that treats nutrition like a system — with real calorie targets, portion math, and a grocery workflow that actually saves time.
