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.

Upgrade your sleep, focus & productivity with Flowing, the third sequel to popular Best of 2014 app Windy. Imagine you could sleep outside in nature instead and enjoy the sights and sounds of wonderful streams, waterfalls & rivers recorded in psychoacoustic 3D for headphones. As if you were there. And if you felt like it, imagine you could mix in some extra 3D nature sounds such as rain on a tent or birds in the trees around you. Get the great sleep you deserve. Flowing integrates deeply with my other apps Windy, Sunny and Away and is compatible with Thunderspace and Sleepy Fan. Over 5,000,000 people have enjoyed them so far. Many use them to sleep better, to meditate, or to focus on their work or studies. Some use them to help their kids sleep. And I believe Flowing is a fantastic addition. Flowing's natural streaming water delivers a versatile white noise ambience that drowns out the noise around you. ≈ Fantastic Audio Quality ≈ All flowing water and nature sounds in Flowing were recorded with a psychoacoustic microphone that captures sound the way you hear. The same principles that work for 3D movies and 3D glasses also work for 3D sound with stereo headphones. All audio is perfectly looped and encoded in AAC for a fantastic listening experience. ≈ Customize ≈ Flowing's fantastic nature sound mixer lets you mix in high-quality nature sounds & music. ≈ Features ≈ + Six high-quality flowing water scenes in 3D for headphones. + Three incredible musical masterpieces by Hollywood's rising star composer David Bawiec. + 3 guided meditations by Australian rising star Lua Lisa. + Sleep & meditation timer. + Mix in music, rain, rain on tent and birds. + Illustrations by the world's best nature illustrator, Marie Beschorner. + Motion-controlled 3D parallax sceneries. ≈ Questions? ≈ Tweet @taptanium, email franz taptanium com or send an email through the in-app contact support page.

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.
