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

Entraina is a precision sound and breathwork studio built on ancient wisdom and modern neuroscience. Designed by a meditation practitioner, not a wellness company. Pay once. Use forever. No subscription. — SOUND ENGINE — Layer solfeggio frequencies, binaural entrainment, noise, and nature sounds into a mix that is entirely your own. Each solfeggio tone corresponds to a chakra — from 396 Hz (Root, grounding) to 963 Hz (Crown, transcendence). Binaural and Monaural beats guide your brain into Delta, Theta, Alpha, Beta, or Gamma states. Seven curated presets — Morning Energy, Focus Flow, Meditation, Deep Sleep, and more — are ready the moment you open the app. — SRI YANTRA — The Sri Yantra is one of the most powerful sacred geometry symbols in existence. Forty-three interlocking triangles representing the union of masculine and feminine forces, the expansion of consciousness from the bindu point outward into creation. Entraina renders it in full animated geometry, synchronized to your breath. For many, it is the most meditative visual they have ever encountered. — PRANAYAMA — Six guided breathing techniques rooted in tradition: Box Breathing, 4-7-8 Relaxation, Coherent Breathing, Wim Hof Recovery, Physiological Sigh, and Alternate Nostril. Each phase — inhale, hold, exhale — is guided by the animated Sri Yantra and precision CoreHaptics feedback that rises and falls with your breath. Premium unlocks three advanced techniques. — DEEPLY INTEGRATED WITH IOS — • Siri Shortcuts: "Hey Siri, start Focus Flow on Entraina" • Live Activities: breath phase and countdown on your Lock Screen and Dynamic Island • Home Screen Widget: your current mix at a glance • Apple Health: mindfulness sessions written to Health automatically • Accessibility: full VoiceOver and Dynamic Type support throughout — PREMIUM — One purchase unlocks: full Mixer access, unlimited custom audio presets, custom breath pattern saving, and three premium pranayama techniques. No subscription. No recurring charges. — THE MUSIC BEHIND THE APP — Entraina was inspired by Orange Evolution, a mindful music project creating original compositions for meditation, focus, sleep, and healing. The same ear that shapes that music shaped this audio engine. Entraina is not a guided meditation app. There is no narrator, no gamification, no streaks. It is a tool — precise, beautiful, and silent in all the right ways — for those who already know the value of going inward, and for those just beginning to discover it. Binaural beats and entrainment technology are not intended to diagnose, treat, cure, or prevent any disease.

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.
