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.

Locket is a widget that shows live photos from your best friends, right to your Home Screen. You and your best friends will see new pictures from each other every time you unlock your phone. It’s a little glimpse of what everyone’s up to throughout the day. HOW IT WORKS 1. Add the Locket widget to your Home Screen 2. When a friend sends you a photo, it instantly appears on your Locket widget! 3. To share a pic back, tap into the widget, take a pic with the camera, and then hit send! It appears right on your friends’ Home Screens FOR YOUR CLOSE FRIENDS • To keep things friendly, you can only have 20 friends on the app. • On Locket, there’s no worrying about follower count, just add your best friends and family and live in the moment. • With Locket, you’re able to be real and share photos to the people that matter. REACT TO FRIENDS' PHOTOS • Send a Locket reaction to your friends to let them know you saw their image. • They’ll get a notification and you’ll love watching the emojis rain down on your photo. • We don’t count or track the reactions, so you can be real and authentic without worrying about likes and filters like other platforms. BUILD A HISTORY OF YOUR LOCKETS • As you and friends snap Lockets, you’ll build up a history of all images sent. • Share them out as photos or use our video recap feature to stitch together the memories of you and your friends, capturing those “love it” moments. • Locket will also make you a recap video at the end of every month with all of the photos you've shared. ADD LOCKETS FOR YOUR BESTIES AND CRUSHES • Decorate your home screen with more photos and images dedicated to your crush or your bestie • Add the “Crush” or “Best Friend” picture widget, and see photos only from that person. Plus, you can send images just to that person too! Here’s what our users say: “I love this app because I get to share cute pictures to my friends” - HI “AMAZING SO WORTH IT” - rikkibear29282902 “Best app made this year” - johanjodel_ Plus, users love our camera (so you’ll love the photos!) - @sonnielove3 on Twitter even said, “It’s sum about that locket camera” Download the free app! We’re keeping Locket free so you can send photos to the people that matter (friends, family, bestie, etc.). With Locket, your phone will feel like it’s bringing you closer to your best friends.

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.
