02

Domain and name

15 minutes

AI PROMPT

Suggest 15 short, memorable brand names for an app that does this: Snap your power bill and see your usage trend with simple saving ideas. It is for Renters and homeowners watching their power bills. For each name, give a matching .com domain idea and one sentence on why it works. Avoid names of existing well known companies.

03

Trademark basics

30 minutes
  • Search the official US trademark database (tmsearch.uspto.gov) for your name, and also search Google and the app stores for apps with the same or a similar name.
  • If a similar name already exists for similar software, pick a different name now. Changing it later is expensive.
  • Filing your own trademark is optional at the start. Many founders file once they have paying customers. This is general information, not legal advice, so talk to a trademark attorney before filing.
04

AI build kickoff

20 to 40 minutes
  • Open your AI coding tool (Claude, Cursor or Lovable) and start a new project called Energy Bill Coach.
  • Paste the prompt below exactly as written. Let the AI finish, then run the app and click through every screen.
  • If something breaks, copy the full error message back to the AI and ask it to fix it. Repeat until it works.
  • Suggested stack: Next.js web app plus Expo mobile app, shared Supabase backend. You can tell the AI to use it, or let it choose.
AI PROMPT 1 OF 3

Build a web and mobile app called Energy Bill Coach. Create signup, a home profile (home type, size, heating type, number of people) and an upload screen for bill photos or PDFs.

05

Server and hosting

30 to 60 minutes
  • For the web app, the simplest path is a host that deploys straight from GitHub (for example Vercel, Render or Railway). A small VPS works too if you are comfortable with servers.
  • For the mobile app, use Expo so the same code runs on iPhone and Android. Test on your own phone with the Expo Go app while you build.
  • Create a free Supabase project for logins and your database, then paste its URL and key into your app settings (never into public code).
  • Put your code on GitHub so you never lose it and can deploy with one click.
AI PROMPT

My app Energy Bill Coach is built with Next.js web app plus Expo mobile app, shared Supabase backend. Walk me step by step through putting it online: creating accounts, environment variables, connecting my GitHub repo, connecting my domain, and turning on HTTPS. Assume I am a beginner and explain each click.

06

Backend and data

1 to 3 hours
  • Now build the core feature. Paste the prompt below into the same project so the AI keeps the context.
  • After it runs, test it with real looking data. Try it the way a customer would, including mistakes like empty fields.
  • Ask the AI to add basic checks: required fields, friendly error messages, and nobody seeing another user's data.
AI PROMPT 2 OF 3

Send each uploaded bill to an AI model to extract billing period, kWh used, gas usage if present and total cost into structured fields the user can correct. Show a chart of usage and cost by month and highlight the biggest jumps compared to the same month last year.

07

Frontend and design

1 to 3 hours
  • Make it feel like a real product. First paste the design prompt, then the feature prompt below it.
  • Pick one brand color and one font and stick with them everywhere.
  • Show it to 3 people who match your customer and watch them use it without helping. Fix whatever confuses them.
AI PROMPT 3 OF 3

Redesign every screen of Energy Bill Coach so it looks clean, modern and trustworthy for Renters and homeowners watching their power bills. Use one brand color, generous spacing, clear buttons, and make it work well on phones. Add a simple logo using the name Energy Bill Coach.

AI PROMPT 3 OF 3

Generate three plain language saving ideas each month based on the home profile and trend, with a checkbox to mark tried. Add a monthly email summary and a Stripe paid plan for landlords tracking several units.

08

Go live

1 day
  • Deploy the web app to your host and connect your domain. Check that https:// works and that sign up, log in and the main feature all work on the live site.
  • For the app stores: build with Expo EAS, then create developer accounts. Apple charges $99 per year and Google Play charges a one time $25. Store review can take a few days, so submit early.
  • Add a privacy policy and terms page. Your AI tool can draft them, and app stores require a privacy policy.
  • Set up simple analytics so you can see visits and sign ups.
AI PROMPT

Write a checklist to launch Energy Bill Coach (web and mobile) with everything I might forget: domain, HTTPS, privacy policy, terms, analytics, error monitoring, backups, and App Store and Google Play submission, a support email.

09
