Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.

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.

DUD3P0 is a bring-your-own-key research tool, reasoning partner, and cognitive amplifier. Point it at something hard — a question to research, a system to design, a problem to think through — and it reasons out loud, labels its uncertainty, cites what it leans on, and writes real code at length. Every claim ships with an auditable receipt. BRING YOUR OWN KEY You supply your own model provider key. It's stored on-device in the iOS Keychain and is never bundled with the app, never hardcoded, and never sent anywhere except directly to the provider endpoint you chose. Works with OpenAI, any OpenAI-compatible gateway, and local endpoints like Ollama and llama.cpp. RESEARCH MISSIONS Turn a question into a structured, receipt-backed dossier. A quick setup — question, domain and rigor, sources, context, depth — then P0 runs the work through six reasoning phases: Framing, Decomposition, Investigation, Drafting, Verification, and Convergence. You get sections grounded in evidence, each carrying its receipts and citations, plus a full Process Log of every step. HONEST BY DESIGN - No analytics, no telemetry, no account, no sign-in. - Honest empty and error states — before a key is connected, the app tells you, and it never fabricates an answer when no model is reachable. - An on-device reasoning floor keeps core logic available even without a cloud key. ALSO INSIDE - Real BYOK chat over your own key, with honest "thinking" and error states. - A logic lab that checks validity, tautology, contradiction, and equivalence by computing truth tables — receipts you can trust because they're computed, not guessed. - Real, runnable code with the reasoning behind it. YOU OWN IT One-time purchase. No subscription, no upsell, no ads. Your key and your work stay on your device. INTENDED USE DUD3P0 is for research, reasoning, and code. It is not intended for generating sexual, violent, hateful, or otherwise objectionable content, and such use is prohibited under the Acceptable Use Policy. When connected to a frontier provider (e.g., OpenAI), that provider's content policies apply; with a local or custom model, you are responsible for the content you generate. Note: DUD3P0 requires your own model provider API key (or a local model). It does not include model access or sell credits.

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.
