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.

With an eSIM from Airalo, get connected the moment you arrive at your destination, without worrying about roaming fees, SIM card hunting, or untrustworthy airport wifi. Airalo is the world’s first and largest eSIM marketplace. Browse eSIMs in 200+ destinations — including Unlimited data packages in over 120+ destinations. What’s an eSIM? An eSIM is a digital SIM built right into your phone. No physical card, no fuss. Browse data packages, buy, install, and get online — all directly from the app. Choose from any one of Airalo’s eSIM plans and packages: - Local eSIMs for single-country trips, starting from just $4 USD - Regional eSIMs for multi-country adventures across Europe, Asia, Latin America, and more - Global eSIMs covering 160+ countries in one install — with data, calls, and texts - Unlimited eSIMs for when you want peace of mind without having to worry about your data usage How it works (it's really this easy) 1. Install the Airalo app 2. Choose your eSIM plan based on your travel needs (location, fixed GB or unlimited data, number of days) 3. Buy your eSIM 4. Install the eSIM directly on the Airalo app 5. Turn on your eSIM and get data as soon as you arrive in your new destination Track your usage in real time, manage multiple eSIMs in one place, and top up on the fly — because plans change, and we help you adapt to them. PS: If your device supports keeping two lines active at the same time, your original SIM can stay active, so you never miss a call or a 2FA code from home. Just make sure Mobile Data and Roaming are strictly assigned to your Airalo eSIM to prevent unexpected charges from your domestic carrier. Why choose Airalo for your eSIM? - Our core values are: Empathy, Ownership, Innovation, Trust, Growth, and Customer First. We embody these values in everything we do: from our work culture to how we treat our customers. We give back, whether it’s donating to disaster relief funds or to other causes that matter, worldwide. - We are fully transparent about our product, including the fair usage policy and data cap for our Unlimited data packages. - Over 30 million travelers trust us to keep them connected across 200+ destinations. Why travelers love Airalo: - Quick and efficient multi-lingual customer support - A wide range of flexible and affordable eSIM plans across destinations, timeframes, and data packages - Unlimited eSIM data packages with no hotspot limit - No hidden fees or surprise charges - eSIM options for calls, text, and phone numbers - Easy top-up FAQs Can I use my SIM card at the same time as an eSIM? - Yes, most devices allow you to use multiple SIMs and/or eSIMs simultaneously. You can keep your primary line active to receive text messages, calls, and 2FA authentication (just remember that these will be subject to roaming fees). Do Airalo eSIMs come with phone numbers? - Yes, we offer both options. Some of our eSIMs come with a phone number that includes data, calls, and texts, while others are data-only packages designed purely for internet connectivity. You can easily check which features are included in the plan's details before purchasing. Can I make phone calls and send text messages with an Airalo eSIM? - Yes, if you choose an eSIM that specifically includes data, calls, and texts. For data-only eSIMs, you won’t be able to make traditional phone calls or send SMS, but you can still use internet-based apps like WhatsApp to stay in touch seamlessly.

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.
