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.

FLAMELET Flamelet is a very creative app for generating fractal art in a playful way. It does this by implementing the fractal-flame-algorithm, originally invented by Scott Draves, in a very versatile and efficient way. There is literally an endless number of possibilities, and you never will have seen all. Flamelet was designed from ground up for mobile devices, is easy to learn, but hard to master. This makes it an app, which has the potential to never become boring. DISCOVER YOUR CREATIVITY Flamelet gives you the freedom, either to create your own art from scratch, or to generate random flames and modify them. There are numerous flame-generators included, all of them with the potential to generate endless beauty. Speaking about art, the app can render your creations in a very decent quality, directly on the device, without any additional costs. ACTUALLY, CREATE FRACTAL ART Unlike to those fractal-zooming/scrolling-apps, Flamelet allows you to actually create fractal art. Either from scratch or by just modifying already created art with your fingertips. Both, a playful and an exact approach are supported: you may just drag around controls or enter exact numerical values. Of course, many combinations of formulas are already well-known, but you can try out your own ideas or just play around to find out new combinations. EXPLORE INIFINITE POSSIBILITIES Flamelet offers a lot of features to play around with: • create limitless combinations of functions, final transforms, transform groups, point transforms and color transforms • make use of about 90 included transforms • influence the tone mapping (balancing, contrast, …) • edit the background (use single color, gradients or images) • apply symmetry (point or axis symmetry with several options) • adjust colors (either by adjusting or creating gradients or by using images) PLAY AND RELAX While creating something from scratch can be very rewarding, just playing around with beautiful shapes can be much fun, and even be relaxing or healing. For this kind of use, Flamelet offers a large library of flame-generators, which create an endless number of random beauty. Additionally, there is the mutagen-module, which allows you to generate random variants ("mutations ") of a selected base flame in a very playful way. SHARE AND EXPORT You can easily share your flame parameters and rendered images with others from within the app. NO HIDDEN COSTS, NO ADS, WORK OFFLINE OR HOWEVER YOU WISH Everything is included when you purchase and install Flamelet. There are about 50 example flames, 12 images and 9 tutorials to get you started. The only other thing you need is your creativity (and your device to render your images). There are no ads, no artificial limits, no subscriptions, no loot-boxes, you have not to be online, …, and we do not collect any of your data! It’s just you – and your art. Have fun ! :-)

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.
