Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Thelo - Body Scan–Powered AI Personal Trainer Thelo is an AI personal trainer built on proprietary body scan technology. Instead of generic workouts, Thelo uses a smart body scanner to analyze your body fat, muscle balance, structure, and recovery — then builds AI personal training plans that adapt as your body changes. This is training designed around your body, not averages. AI Personal Training Built From Your Body Scan Your body is unique. Your training should be too. Using a visual body scan, Thelo identifies: • Muscle imbalances and weak points • Genetic structure and proportions • Areas limiting growth or causing plateaus • Which muscles are recovered — and which aren’t Your AI personal trainer updates your workouts automatically based on this data. Smart Workouts That Adapt Daily Thelo’s AI personal training system adjusts your workouts based on: • Your schedule and available time • Gym or home equipment • Fitness level and training history • Recovery and recent workload No fixed plans. No wasted sessions. Just training that fits your life. Track Real Body Change, Not Just Weight Thelo’s body scanner helps you track what actually matters: • Daily body fat tracking • Body measurement changes over time • Muscle-specific recovery insights • Weight logging with full history • AI-guided progressive overload Your AI personal trainer shows you why progress is happening — or why it isn’t. See Progress With Clear Body Scan Insights Thelo turns your body scan data into clarity: • Visual body scan comparisons • Muscle-by-muscle progress breakdowns • Recovery vs workload balance • Objective feedback, not guesswork It’s AI personal training with transparency. Who Thelo Is For • Gym-goers tired of generic programs • People stuck despite training consistently • Anyone who wants data-driven progress • Lifters focused on physique, symmetry, and longevity Why Thelo Is Different Most fitness apps start with workouts. Thelo starts with a body scan. Powered by an intelligent body scanner and adaptive AI personal trainer, Thelo delivers AI personal training that evolves with you. Train smarter. Train for your body.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
