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.

Can't sleep? Try Away, a high-quality sleep ambience app by award-winning audio technology innovator Franz Bruckhoff. Away simulates a rich forest full of nature sounds to explore and discover, day and night, from morning til evening. Adjust the daytime and move the virtual microphone around to find your favorite spot to unwind and sleep. Away features one of the most advanced nature sound field engines in the world, delivering an unprecedented nature audio listening experience. Hear the forest come to life around you. Get Away today, sleep great tonight! Taptanium™ certified nature audio means that you hear only crystal clear nature sounds with absolutely zero human made noise intrusions. No people, no airplanes, no cars. Just nature. Infinite playback. Taptanium™ certified nature audio comes from the best sources such as Hawaii and has been mastered to perfection with the highest attainable level of attention to detail, utilizing artificial intelligence to detect even the most distant human-made noise intrusions that humans are almost incapable of recognizing under normal conditions. Only the highest quality nature sounds in the world are able to receive this certification. Away features Taptanium™ neural 3D audio™. If you put on headphones, Away can create an incredible sense of immersion. The nature and water plays all around you, not just on your ears. This is called externalization, and it's encoded in a way that your brain naturally decodes as if you were there. You will sleep, relax, meditate and focus better with Away because Away masks unwanted noise. Your ears will love Away because Away plays soothing high-quality nature sounds recorded in 3D. Your eyes will love Away because the forest comes as a motion-controlled 3D parallax illustration with daytime transitions. Get the great sleep and productivity you deserve. Hear the wind and leaves swirling all around you, birds singing during the day, Hawaiian Coqui frogs singing at night and distant American Bull Frogs resonating through the valley. Get closer to the river or waterfall or retreat to the calm pond in the back with ducks during certain times of the day. In the morning, listen to the funny sounds of wild Hawaiian chickens recorded on the beautiful Garden Island of Kauai in 3D. Hear birds waking up and birds singing happily. Away is a treasure chest of sounds. And if you like, blend in music specifically composed and conducted for Away in Hollywood. Away includes so many things: • The Great Away Forest with a great variety of nature sounds to discover • Find your favorite spot to listen or sleep within the forest • Change the time of day and hear the soundscape adapt • Unlimited playback time, infinitely looped (very long loops) • Taptanium™ neural 3D audio™ (incredibly immersive) • Taptanium™ certified quality nature audio • Mixer: Mix and match some extra nature sounds and music • Adjustable fade-out and sleep timer • Full background audio support • Universal app for iPhone and iPad • No in-app purchases • No subscription • Beautiful audiovisual experience • Music composed for Away in Hollywood • NEW: Optimized for iPhone X, XR, XS & XS Max, 11, 11 Pro, 11 Pro Max & iPad Pro!

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.
