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.

Log meals your way and see calories, macros, and saturated fat without giving up control. Calometric is a premium calorie counter and macro tracker for iPhone and Apple Watch. Snap a meal, scan a barcode, speak, search foods, or read a nutrition label. Every result is a starting point you can review and edit before it enters your food diary. FIVE WAYS TO LOG • Photo Take a meal photo and receive an editable estimate of the foods, portions, calories, and macros. With your permission, Calometric sends a resized copy of the photo to cloud AI for analysis. • Barcode Scanner Scan packaged food and look it up in the community-maintained Open Food Facts catalog. Your device reads the barcode; the product lookup uses the internet. • Voice Say what you ate using on-device transcription on supported devices and languages. • Search Find food in a built-in collection of about 300 curated USDA items, even when you are offline. • Nutrition Label Point your camera at a nutrition label to read calories and nutrients on your device, with clear per-serving or per-100 g/ml values. TRACK SATURATED FAT, TOO Saturated fat now follows your meal from capture to history whenever the source provides it. • Review calories, carbohydrates, protein, total fat, and saturated fat together • Set an independent daily saturated-fat goal • Follow your progress from the Dashboard • Edit values before saving and when updating a meal • Keep saturated fat when copying meals or saving favorites • Include it in CSV exports and Apple Health when authorized If saturated fat is not available, Calometric says so instead of counting it as zero. MAKE DAILY LOGGING EASIER • Set daily calorie and macro goals • Check progress at a glance • Follow weekly calorie and macro trends • Adjust foods, portions, and servings • Save favorite meals and copy meals you eat often • Search your diary and export it as CSV Whether you are tracking macros, keeping a food diary, or working toward a personal weight-loss goal, you stay in control of every entry. BUILT FOR YOUR APPLE DEVICES • Independent Apple Watch app and watch-face complications • Home Screen and Lock Screen widgets, plus Control Center controls • Siri shortcuts and Spotlight meal search • Optional meal-history sync through your iCloud account • Optional Apple Health sync for calories, carbohydrates, protein, total fat, and saturated fat when known and separately authorized • Support for VoiceOver, Dynamic Type, Reduce Motion, and Reduce Transparency MEET THE OPTIONAL NUTRITION COACH Ask about meals, macros, hydration, grocery choices, dietary patterns, or fueling for a workout. With your permission, the Coach can use your active goal, today's totals, and up to seven days of totals when available to make its general-wellness guidance more relevant. The Coach requires a separate auto-renewing monthly subscription. Access includes up to 20 completed messages per UTC day and 300 per subscription billing period. Food logging never requires a Coach subscription, and Coach messages never use photo-scan credits. The Coach is not medical advice and cannot diagnose or treat a health condition. AI can be wrong, so check important guidance with a qualified professional. CLEAR CHOICES FROM THE START • No Calometric account or login required • No ads and no tracking • Voice transcription, food search, and nutrition-label reading run on device • Photo analysis and the Nutrition Coach process content in the cloud after separate permission • Barcode product lookups contact Open Food Facts • Your app purchase includes 100 photo scans that do not expire • Optional 100-scan packs are available if you want more • The Nutrition Coach subscription is separate and never required for food logging Privacy Policy: https://calometric.app/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Snap.

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.
