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.

Boba is the first local AI calorie tracker that runs entirely on your phone. Point your camera at food. Get calories, protein, carbs, and fat in seconds. No cloud. No account. No subscription. Ever. We built Boba because we were tired of calorie apps that hide basic features behind $30-a-year paywalls, send every photo of your lunch to someone else's server, and still get half your food identifications wrong. Boba is different by design. HOW IT WORKS 1. Open the app. 2. Point your camera at food. 3. Get calories and macros in a few seconds. 4. Log it to your day. That's it. No account, no email, no credit card, no paywall. ON-DEVICE AI Boba runs a 2-billion parameter vision-language model, fine-tuned on a custom food dataset. The entire model ships inside the app — bundled at install time, no first-launch download, no cloud calls at inference. Everything happens on your iPhone's Neural Engine. Test set accuracy: 89.8 calorie MAE. The best on-device food AI we could build. PRIVACY BY ARCHITECTURE Boba doesn't collect your data because the app is designed so it can't. There are no Boba servers that receive your photos. There is no user database. There are no analytics. The only outbound request the app ever makes is to Open Food Facts when you scan a barcode — and that query contains only the barcode digits, nothing else. Your meals, weight, goals, and photos stay on your phone. Delete the app and everything is gone. That is the entire data flow. WHAT'S INCLUDED • AI food scanner — camera → calories in seconds • Barcode scanner — Open Food Facts integration • Manual meal entry • Daily calorie + macro tracking • Water tracking • Weight tracking • Intermittent fasting timer • Dark mode • Export all your data anytime No ads. No subscriptions. No tracking. No paywalls on core features. Ever. WHO IT'S FOR • People who want to lose, gain, or maintain weight without the corporate tracker experience • Anyone allergic to subscriptions and dark patterns • Privacy-conscious users who don't want their eating habits logged to a server • Gym-goers who track macros • Intermittent fasters • Anyone who believes calorie tracking shouldn't cost $30 a year ABOUT THE MODEL Boba's vision model is a fine-tuned 2B VLM built by Doses AI. It identifies dishes, estimates portions, and outputs per-item nutrition locally. We'll improve it over time. Future major model upgrades may be offered as optional in-app upgrades, but the core app — scanning, logging, tracking - will always be free. IMPORTANT Boba is a wellness tool, not a medical device. Calorie and macro estimates are AI approximations and may be inaccurate. Boba does not diagnose, treat, or prevent any disease.

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.
