An AI routine builder for
fitness, skincare & nutrition.

A routine builder is different from a habit tracker. A tracker logs what you already do; a builder writes the plan for you. Quartz uses an AI model trained to combine three of the most personal areas of self-care — training, skin, and food — into one consistent routine that fits a specific person, not a generic persona.

You answer a short series of questions about your body, your goals, your skin, your kitchen, your equipment, and how busy your week looks. Quartz uses those signals to design a 30-day plan with daily tasks, optional product picks, and clear explanations for every recommendation.

Quartz is built for people who don’t want to manage five different apps for workouts, meals, skincare, journaling and shopping. If you’ve ever opened a fitness app, a skincare quiz and a meal-planner in the same week and ended up doing nothing, this is the tool to consolidate that into a single, structured plan.

Quartz combines deterministic rules (e.g. dermatology-safe ingredient ordering, progressive overload for strength training, balanced macro targets) with generative AI to write the actual day-by-day plan. That means recommendations are explainable and consistent, not just “whatever the model felt like saying.”

Most apps personalize once at signup and then never change. Real life isn’t static: you get sick, travel, change goals, run out of a product, or have a brutal week at work. Quartz watches for those signals (skipped tasks, chat feedback, schedule changes) and rewrites the rest of your plan so it stays realistic. That’s the difference between a plan you abandon and a routine you actually finish.
