Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

App Store description

Cookbell is the timer you reach for when one countdown isn't enough. Dinner is never just one thing. The eggs need six minutes, the pasta nine, the tea is steeping, and the bread is in the oven. A single timer makes you choose. Cookbell lets you run them all at once — each as a big, readable card with its own name, a live progress ring, the time remaining, and the exact time it will finish. And when a timer is done, it actually tells you — even if your phone is locked or in your pocket. Every running timer schedules its own time-sensitive alert with a distinct sound, so you know at a glance (and by ear) which dish is ready. ONE TAP TO START Skip the fiddly setup. Tap a preset and a timer is running instantly: • Soft, Medium and Hard Eggs • Pasta, Rice, Quinoa, Risotto stir • Green Tea, Black Tea, French Press, Pour Over • Steak rest, Pizza, Bread, Roast Veg, Bacon • Power Nap, Laundry, Focus Sprint, breaks and stretches MAKE IT YOURS Build a custom timer with simple hour/minute/second wheels, give it a name, pick one of eight alarm tones, choose a color and an icon — then save it as your own one-tap preset for next time. A TONE FOR EVERY TIMER Eight distinct alarm sounds — Classic Bell, Digital Beep, Soft Chime, Marimba, Alarm Buzz, Cuckoo, Deep Gong and Sonar Ping — so a quick listen tells you which timer finished without even looking. TEMPERATURE & DONENESS GUIDE The Cooking Guide now includes a Temps tab: 29 entries across beef, pork, poultry, fish and seafood, lamb, eggs, ham, and reheating — each with the USDA safe minimum, a chef's preferred target range, rest time, and visual doneness cues. Searchable. °F / °C toggle. All offline. STOPWATCH MODE Need to track how long something has been going rather than how long is left? Flip to Stopwatch in the Custom tab to start a count-up. Pause and resume, and the card shows elapsed time in the same ring layout. TIMER HISTORY Every completed timer is logged automatically — up to 50 entries. Open Settings → History to see what ran and when, and tap Run Again to re-use it instantly. MEAL PRESETS Build "Sunday Roast", "Ramen Night", or "Thanksgiving" once — give the meal a name and emoji, add each timer's duration, color, and alarm tone — then tap Start All to launch them all simultaneously. Edit or delete meals any time from the fork-and-knife icon in the Add Timer sheet. SERVE TOGETHER PLANNING Saved meals now include a serve-time board. Cookbell finds the longest item, shows when each shorter item should start, and can stage those shorter timers as automatic start reminders followed by the real cook timer. It is built for the part of dinner where pasta, vegetables, bread, sauce, and resting meat all need to land together. SAVE COOKING GUIDE ITEMS AS PRESETS Expand any entry in the Cooking Guide Timings tab and tap "Save Preset" to add it directly to Your Presets. A confirmation badge confirms the save — no manual entry needed. ALTITUDE ADJUSTMENT FOR BOILING TIMES Living above sea level? Go to Settings → Cooking Guide → My Elevation and choose your elevation tier. Eggs, pasta, and grains in the Timings guide are automatically adjusted using the CSU Extension formula (+30 sec per 1,000 ft). A mountain badge confirms the adjustment is active. BUILT FOR REAL COOKING • Pause, resume, reset, or add a minute on any timer • Restart a finished timer with one tap • Keep the screen awake while you cook • Crisp haptics and a calm, dark, kitchen-at-night design • Works beautifully on iPhone and iPad PRIVATE BY DESIGN Cookbell runs entirely on your device. There is no account to create, no network connection, no analytics, and no tracking of any kind. Your timers are yours. Whether you're plating a four-part dinner, brewing the perfect cup, timing a workout, or just remembering the laundry, Cookbell keeps every countdown in view and makes sure none of them slip by. Download Cookbell and never burn the garlic again.

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

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.
