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.

Most productivity apps assume you think in straight lines. Flint doesn't. Flint is a daily planner built specifically for ADHD brains — the kind that get overwhelmed by too many options, struggle to start even when the task is small, and need to know what to do right now, not just someday. It works out of the box. No system to design. No complicated setup. Open it, check in, and get moving. HOW ARE YOU TODAY? Every morning starts with a stoplight check-in. Green, yellow, or red — one tap tells Flint how much you have to give. Your day adjusts around that. Not the other way around. A visual capacity bar shows you how full your day is before you've even started stressing about it. When tasks overflow, they don't disappear — they wait in your Overflow Tray, guilt-free, ready when you are. YOUR DAY, YOUR WAY See tasks as a list or flip to Timeline view — a scrollable hourly schedule that shows exactly what lands where in your day. Colour-coded by priority. Annotated with energy levels so you can match your hardest tasks to your sharpest hours. HELP ME START Starting is the hardest part. Flint's built-in routines — Brain Dump, Clear Inbox, Plan Tomorrow, Quick Capture, Plan a Project, Weekly Review — walk you through each step and link directly into the right part of the app. You never have to figure out what to do first. CAPTURE ANYTHING, INSTANTLY Think of something? Tap the brain button. Type it, speak it, or write it in a note. Voice capture listens to how you describe a task and automatically sets the priority and schedule. Say "urgent" or "tomorrow" and Flint handles the rest. Drop a brain dump into Notes and tap Extract Tasks — Flint's AI reads your note and pulls out the action items for you to review and add in one tap. TASKS THAT UNDERSTAND YOU Every task can carry an energy level — low, medium, or high focus. Match your work to your actual capacity, not your ideal capacity. Set priorities, estimated times, subtasks, reminders, and due dates. Assign everything to a project. Tasks with reminders use native iOS notifications. No account required. Everything lives on your device. PROJECTS AND NOTES Organise work into projects with custom colours and icons. See progress at a glance. Link notes to projects. Pin the ones that matter. Everything connected, nothing buried. PRIVATE BY DEFAULT Flint stores everything locally on your device. No account. No subscription required to access core features. No data sent to anyone. Flint won't fix your ADHD. Nothing will. But it will give you a calm, clear place to land when your brain needs a starting point — and that's often all you need.

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.
