Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Get room temperature estimations and localized climate insights with Room Temperature Checker! Room Temperature Checker is a smart utility designed to help you track and estimate indoor ambient temperatures. Because smartphones do not contain built-in ambient air temperature sensors, Room Temperature Checker utilizes a thermodynamic estimation model that combines local outdoor weather conditions, home insulation parameters, solar UV indexes, and your personal calibration feedback. Whether you want to monitor your indoor climate or track local outdoor weather conditions, Room Temperature Checker provides a convenient and beautifully designed dashboard. ► KEY FEATURES: • Smart Indoor Temp Estimation: View calculated indoor ambient temperature estimations based on outdoor meteorology, daytime solar offsets, and insulation levels. • Live Local Weather: Check current temperature, relative humidity, atmospheric pressure, wind speed, and UV index for your exact location. • Comfort-Based Calibration: Calibrate your estimations in seconds by selecting how you feel (Cold, Ideal, Hot) or inputting a reference temperature from a physical thermometer. • Insulation Tuning: Adapt the calculation model by configuring your room's insulation quality (High, Medium, or Low) to match your home's building structure. • Smart Climate & Comfort Tips: Receive personalized recommendations (such as ventilation tips or heating/cooling suggestions) to maintain the perfect indoor climate. ► HOW IT WORKS (THERMODYNAMIC ESTIMATION): Since mobile devices do not have external air thermometers, Room Temperature Checker uses local outdoor weather forecasts, relative humidity, and daytime solar UV offsets. By adjusting for your room's insulation coefficient (Good, Medium, or Poor) and calibration offset, the app calculates an estimation of your indoor room temperature. Please note that this is a mathematical estimation model based on environmental conditions. Because iPhones lack built-in physical ambient air thermometer sensors, it is technically impossible to get 100% accurate indoor temperature readings. For best results, use the calibration options. ► GO PRO WITH PREMIUM: Unlock full access to advanced features: • Real-time, continuous indoor temperature estimations. • Smart AI Comfort Analysis & direct ventilation alerts. • 100% ad-free experience. • Advanced, hyper-local weather details and UV forecasting. --- Note: This app estimates ambient room temperature based on local outdoor data and structural parameters. It acts as an estimation and tracking tool rather than a physical hardware thermometer, and cannot guarantee 100% accuracy. It is not designed for clinical or medical body temperature measurement.

Opportunities
AI-GENERATED OPPORTUNITY HYPOTHESES
These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.
Hypothesis 1
Allow users to set custom unit preferences and add other environmental metrics.
Assumption to check: Limited customization options for temperature units
Validate with people who use this workflow before building.
Hypothesis 2
Implement alerts that notify users when the temperature goes above or below set thresholds.
Assumption to check: No alert settings for temperature thresholds
Validate with people who use this workflow before building.
Hypothesis 3
Enhance the UI with more data visualizations and insights about historical temperature trends.
Assumption to check: Simple UI lacking detailed insights
Validate with people who use this workflow before building.
Hypothesis 4
Add functionality for users to track temperatures in multiple rooms or locations.
Assumption to check: No support for multiple locations
Validate with people who use this workflow before building.
Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
