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.

Sismo vibration meter is analyzes the data from the iPhone or iPad accelerometer and builds a vibration spectrum. This allows users to see if an earthquake is happening in their area. Measure all vibrations and earthquakes ! How it works Seismometers are devices used to measure earthquakes. They are also known as seismographs or body tremors. Seismometers are used in seismology to measure the strength and direction of earthquakes. Sismo uses the iPhone or iPad's accelerometer to detect vibrations in the ground. These vibrations are then analyzed to create a vibration spectrum. This spectrum is then compared to known earthquake waveforms. The Sismo iPhone App is the perfect tool for anyone interested in seismology or earthquakes. Sismo is analyzes the data from the iPhone or iPad accelerometer and builds a vibration spectrum. This allows users to see if an sismic activity is happening in their area. Check the vibrations with your phone! Sismo is a seismometer that measures the vibration of the Earth. It is used to study earthquakes and tsunamis.One of the most important tools for seismologists is the seismometer, which is used to measure the vibration of the earth caused by earthquakes. The seismometer can also be used to measure the body tremor of people suffering from Parkinson's disease. Measure vibrations with iPad or iPhone. Always see these vibes with great viewing options. Customize the application with your own colors with 4 views. Special Views ; ● OSCILLOSCOPE The oscilloscope view is arranged for a full hollywood effect and is enjoyable to watch on your iPad or iPhone at your desk. ● METRONOME Metronome view detects harsh vibrations and has a plain appearance. ● GEYSER Geyser view also includes an alarm function and will easily show you the smallest movements like a geyser. You can set the threshold of vibrations listening and the threshold at which the Alarm will sound. ● WAVE The wave appearance can be set as a straight wave or a moving wave, allowing you to measure with high precision. Many views give you the chance to make a full screen. This allows you to focus on data only. You can also use it as a hollywood effect. People around you will be amazed when they see the cinematic view on your device. In addition, you can customize the entire appearance through the settings tab, if you are using your device with a stand, you can easily control the tilt of your stand with the bubble level function, which you can access under the settings tab and you can make accurate measurements with a perfectly flat floor.

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.
