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.

Calling all future scientists! Boys and girls, it's time to put your best thinking cap on! Navigate your Thinkrolls through 270 levels of science-filled mazes in this fun logic puzzle game. Parents, take pride in your children's achievements, as they stretch their brains and solve increasingly challenging physics puzzles, all while having fun! "Thinkrolls 2 delivers exciting puzzle play" - USA Today "Maze puzzler packed with smart, science fun" - Common Sense Media Editor's Pick "An outstanding collection of challenges" - Children's Technology Review Editor's Choice "Masterfully combines silly fun with progressive learning" - Tech With Kids BEST PICK "A masterful sequel to one of my family's all-time favorite apps!" - 148 Apps Kids must use all their wits to navigate 32 spunky characters through 270 levels of increasingly complex mazes. This clever game of logic keeps kids on their toes as they use properties of matter and basic physics to make their Thinkrolls not only roll, but float, glide and teleport through a series of themed chapters. Each gradually introduces a new science concept in an accessible, easy to understand way. As kids explore and master, through trial and error, how to navigate the twists, turns and many pitfalls, they gain confidence in their deductive reasoning and ability to problem solve. Completing the puzzles requires juggling multiple possibilities, but by thoughtfully combining elements and planning moves well in advance, players keep their Thinkrolls happily rolling along. CHAPTER DESCRIPTIONS Accordion - Hone fine motor skills as kids use expansion and compression to open pathways, build bridges and create stairways Water & Barrel - Test theories on what will sink or float to help Thinkrolls avoid water hazards and pass through safely Egg - Experiment with force, acceleration and gravity to walk on eggshells or gently bounce and roll over an intact egg Fan - Give your ball a gravity-defying boost with some aerodynamic lift from a fan Wormhole - Enter the wormholes to teleport through maze walls! Choose the correct exit and use precise timing or risk getting trapped. Battery - Carefully wait for the circuit to switch off before coming in contact with a battery. Light bulb - Enhance visual memory and remember projected moves before the light goes out Bonus - Combination of all science elements and physics concepts in even more complex puzzles MAIN FEATURES • 270 challenging levels with mind-sharpening puzzles • 135 easy puzzles for ages 3-5, 135 hard puzzles for ages 5-9 • Hands-on physics lessons • Experiment with gravity, buoyancy, levitation, electricity, density, acceleration and other science concepts • Enhance logic, spatial cognition, problem solving, memory, observation and more • 32 hilarious super smart characters to play with • Track progress for up to 6 player profiles • Fun brain training for the whole family • Perfect introduction to STEM • Supreme design and beautiful artwork • Original soundtrack and sound design • Language neutral game-play • COPPA compliant, no third-party ads, no in-app purchases PRIVACY POLICY We respect your privacy!

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.
