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.

18 Advanced Brainwave Programs in One App! Sharp Mind induces optimized mental states ideal for school, exam preparation, confidence, problem solving, memory, creativity, confidence and learning. Combine Binaural Tones with iTunes Music, Audiobooks, Spotify * Built-in iTunes Playlist Creator * 21 Soothing Ambient Backgrounds and 10 Gentle Alarm Sounds. * Universal App * iPhone and iPad UIs HD&SD * Headphones/Earbuds must be worn for Binaural Tones to be Effective. To combine Brainwaves and Ambience with Audio from Another App use Background Mode 'Ambience + Other App' in the Background Settings. To use just Brainwaves and Audio from Another App use the "No Background" option for the Background Source. Warning: These are powerful brainwave entrainment programs and should never be used while driving or operating machinery. BrainWave Sharp Mind is unlike any other brainwave entrainment application. Other brainwave and binaural beat applications use only a single brainwave frequency and carrier signal. The Sharp Mind Progressive Brainwave Entrainment algorithms use a series of brainwave programs, multiple frequencies and carrier waves to gently bring your brainwave frequencies to your desired state using a more natural and effective frequency progression. *** Advanced Features *** - Multiple Brainwave programs each specially designed to elevate you to a unique mental state. - Multiple ambient background sounds to choose from. - Adjustable Brainwave Intensity - The intensity of the brainwaves can be adjusted independently of the ambient background sound. This allows you to set the brainwave volume to your comfort level. The application will also save your preference for future use. - Adjustable ambient background volume. - Visual timer countdown indicator. - Automatic saving of preferred brainwave entrainment program and ambient background sounds. - Ability to create your own custom time option. *** Programs Included *** - Brain Energizer: Takes you through a series of brainwave programs and progressively elevates your level of alertness. - High Beta Concentration: Designed to put your mind into the ultimate state of focus and concentration. Ideal when you need to block out surrounding distractions and study. - Creative Brainstorming: A series of brainwave programs that elevates your mind to a state of open-mindedness and creativity. Perfect for when you're stuck on a problem or are having difficulty coming up with an idea. Sit back and plug into this program to completely open your mind. - Creative Problem Solving: The ultimate combination of focus and creativity achieved through a series of brainwave programs and frequency mixes. - Gamma Memory Boost: This program was designed to be used whenever you feel like taking a break and letting what you've just learned sink in. This will help you maximize memory recall. - Beta Confidence Boost: Designed to be taken before a test or presentation. The other programs help you prepare, solve problems, come up with ideas and remember what you've learned. Sharp Mind also includes: - Creative Thinking - Lateral Thinking - Convergent Thinking - Deductive Thinking - Centered Mind - Focus/Concentration - Gamma Creativity Boost - Evening Memory Boost - Full Beta Spectrum - Full Gamma Spectrum * How Binaural Brainwave Entrainment Works * This app uses advanced Binaural Brainwave Entrainment to stimulate brainwave frequencies associated with different states of mind. These brainwave frequencies are in most cases inaudible and therefore must be induced through the use of binaural tones. In this process two different tones are played, one for one ear, and one for the other (headphones or earbuds must be used). When processing these two different tones the human brain perceives the difference as a beat matching the target brainwave frequency.

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.
