A product spec, screen plans, and build steps for your coding agent.

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.

NEWS: Family Tracker was used to locate a missing child - see news report on: http://www.reuters.com/article/net-us-app-missing-idUSBRE8460GZ20120507 ***SUPPORT NOTICE**** We do help everyone who contacts us via our [email protected] email address, but unfortunately most users give bad ratings without ever contacting us for support. Please do contact us if you have any issues, we're always there to help! *************** Family Tracker allows you to track your wife, husband, children and fiancée. You can now find out where they are, at anytime, as long as they have their phones with them. Family Tracker is available for other platforms as well, so you can track (and be tracked by) other devices as well - check our website for more details. Please note that starting with the new iOS4 and supported hardware, Family Tracker runs in the background at all times, and, unlike previous versions of Family Tracker, user intervention is **NOT** needed for you to track them. Family Tracker runs at all times, continuously updating the GPS location of the device. Even if the iPhone is rebooted, Family Tracker will automatically resume tracking and updating its position! So how does this work? Simple. Install Family Tracker on the iPhone/iPad you want to track. From then on, you can use either a web browser or via the Family Tracker app itself installed on your own iPhone/iPad to locate your family member. If the device you wish to track does not support multitasking (for example, older iPhones 3G, iPads), you can still use Family Tracker to locate the family member. Using the web or your own iPhone, you will be able to "ping" the other iPhone. This is done by sending the other iPhone a (free) “Apple Push Notification” which will cause an alert to sound on your family member’s iPhone, even if the phone in is stand-by, just as would happen if the iPhone receives an SMS. As soon as this alert is acknowledged, their GPS position will be recorded, and their location will be updated on a map. If you are using an iPhone yourself to track them, you will be sent a Push Notification to inform you that the family member has accepted your "ping". These notifications will be automatically re-sent every 60 seconds until they are acknowledged. If the recipient is trying to ignore them or does not hear them, this repetition will help acknowledging them. Family Tracker does not need to know your iPhone cell number to function, as it does not send SMS messages for notifications. Your email address is instead used to send free Apple Push Notifications to the iPhones being tracked. These notifications are free, specific to our Family Tracker application, and work anywhere in the world as long as the iPhone and/or iTouch being tracked has internet access via the cellular network or WiFi. Notice: ***Continued use of GPS running in the background can dramatically decrease battery life.*** For this reason, we strongly recommend users to configure Family Tracker to use the "Driving Only" accuracy in the GPS setting. This special mode updates the GPS location only when a significant location change occurs, which results in a tremendous gain in battery life. Additional pro features, such as the ability to see the past locations for the previous 2 weeks, and the ability to set geofences so you are alerted when users that you track enter or leave certain areas are available via an optional iTunes subscription. Subscriptions automatically renew unless auto-renew is turned off at least 24-hours before the end of the current period. Your iTunes account will be charged for renewal within 24-hours prior to the end of the current period. Subscriptions are available for either $1.99/month, or $5.99/3 months, or $9.99/6 months or $19.99/year. Privacy policy & terms of use: http://logsat.com/family-tracker-privacy.asp

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.
