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.

Yes. There's a better way to control your Sonos system. - Speeds up most common tasks (less taps) - Cleaner, more stable and fast interface. - Backward compatibility is king (we support Sonos S1 firmware and also iOS15 devices) - Manage zones and music sources. You control your Sonos. Not the other way around. See the features in action on YouTube (https://youtu.be/aMEuaZPUH58) or read more below. This application is a third party app and not endorsed by or associated with Sonos, Inc. (which is why it is not free) ◆◆◆ A new, intuitive and concise user interface ◆◆◆ SonoPhone is designed to leverage the latest iOS design principles: - Tap or drag the player on the top and you'll find the players view to select a new player and with volume controls for all players. From here you can also enter Zone Management, where you can group and ungroup players with drag and drop. - Tap or drag the Track infos on the bottom and you'll be at the big covers screen - Drag the main menu from any place to the left or right to have instant access to playlist or shortcuts - volume + progress popups: when changing volume or progress of a song, you get popups telling you the actual values. Stop guessing your desired values today! ◆◆◆ less taps for common tasks ◆◆◆ SonoPad tries to optimize most often used tasks to have the least taps needed. In the end you are able to navigate and control your players much more fluently. - Touch To Play: are you sick of always beeing asked what to do when you tap a track or album? SonoPhone defaults to just starting an album or song. A long press still gives you access to all options - you can also change the tap default in the settings menu. Want to build a playlist fast? Just set the default to 'always add to end' and off you go ... - tap an album cover image and the whole album starts to play immediately - aggregated search: search results are collapsed into one view, so you see immediately in what category you have the best results, without switching back and forth - shortcuts to most used functions: drag the main menu to the right to get shortcut buttons for artist, albums, radio and musicservices. - you can control the volume of every player directly from the player selection screen. No need to switch players anymore. ◆◆◆ S1 and S2 devices in one app ◆◆◆◆ - If you still have old S1 devices, the time of always having to change apps is over. We simply display all existing players in the network in one list. Grouping is unfortunately not possible, this is prevented by Sonos. ◆◆◆ Limitations ◆◆◆ - all music services except YouTube Music are supported - no support for administrative features (adding/removing players, music service, ...). You need the official Apps for initial setup of your system, SonoPad will pick up all changes automatically. - no options to set alarms or sleep settings - no playing of music stored on iPhone - no support for discontinued WD100 dock ◆◆◆ Other stuff ◆◆◆ - Sonos is registered trademark of Sonos, Inc.

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.
