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.

Boost your child's brain power and intelligence! Thinkrolls is an award-winning logic puzzle game that helps young kids develop reasoning and problem solving skills through a delightful and engaging gameplay. Get it now and let your little geniuses amaze you with their mental abilities and logic skills! ________________________________ ** Featured 'Best New App' on the App Store's Home Page in more than 70 countries ** ** Ranked #2 in US App Store, Education category ** • Parents’ Choice Award Winner • Named one of the "10 Top Kids Apps of 2014" by USA Today! • "Adorable physics platformer creates little problem-solvers." - Top Pick by Common Sense Media • "Thinkrolls has actually become a family affair...I enthusiastically recommend it." - 148 Apps • "Another smash hit by these ingenious and award winning developers." - Teachers With Apps • Editors' Choice by Children's Technology Review & Tech With Kids ________________________________ THE MISSION Have a blast navigating your Thinkrolls through a series of obstacles in brightly patterned mazes. The goal is to solve the puzzles and roll through the end of the maze where a new Thinkroll waits to be unlocked and lead the next quest! HOW TO PLAY The app offers 207 clever puzzle levels filled with fun science concepts. Seven playful elements with unique physical properties are gradually introduced. Kids will discover through hands-on manipulation how to use these objects to their advantage and clear a path. • Cookies • Munch them to clear a path or resist those treats to avoid getting trapped! • Crates • Push them to fill gaps or stack them to reach higher ground. • Balloons • Burst them on spikes to get them out of your way. • Rocks • Get a crash course in Newtonian physics by dropping heavy, dense boulders to break through cracked ground. • Jelly • Bounce Thinkrolls and objects on springy jellies to launch them up. • Fire • Use ice blocks to put out the fire and safely pass through. • Elevators • Timing is added to the mix! Synchronize movements of two different elevators to navigate through the maze. MASTER THE ART OF THINKING Little players will master the art of thinking while using to their advantage force, acceleration, buoyancy, heat, elasticity and gravity to reach the end of the maze. The puzzles gradually build upon successive science lessons to strengthen observation, creative thinking, logic, problem solving, spatial cognition and memory. There are unlimited tries and no penalties. Thinkrolls not only challenges the brain but also develops and rewards patience and perseverance. As kids try different combinations to achieve their goal, they intuitively learn through trial and error what works. They must think ahead, use precise timing and rely on their memory to reunite their Thinkroll buddies. ________________________________ MAIN FEATURES • 207 levels with mind-sharpening puzzles • Easy mode for ages 3-5, hard mode for ages 5-8 • Hands-on physics lessons • Experiment with gravity, heat, buoyancy, speed, elasticity, friction and other science concepts • Enhance logic, spatial cognition, problem solving, memory, perseverance • 26 hilarious, super smart characters to play with • Fun brain training for the whole family • Track progress for up to 9 player profiles • Supreme design and beautiful artwork • Original soundtrack and sound design • Language neutral game-play • COPPA compliant, no 3rd party ads, no in-app purchases More info: avokiddo.com ________________________________ 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.
