Custom Browser App, Built for You: Your Own Offline Planner, Tracker or Dashboard

About this product

CUSTOM BROWSER APP, BUILT TO YOUR SPEC
Tell us what you need to track, plan or calculate. We design and build it as a single offline .html file that runs in any browser, on any device, with no login and no subscription. One flat price: $100.

WHAT YOU GET

• A one-file browser app designed around your workflow, up to 6 views (for example: dashboard, log, calendar, budget, checklist, settings)
• Your own fields, categories, formulas and colours, not a template with the labels changed
• Works offline on Windows, Mac, iPad, Android and Chromebook, saves to the device, exports to CSV or JSON
• Printable views and a dark mode
• One free bonus edition of the same system: spreadsheet, Notion, printable PDF or GoodNotes
• Two rounds of revisions after the first draft
• 30 days of fixes after delivery

HOW IT WORKS

1. Email hello@browserhub.app with a short description of what you want the app to do. A paragraph is enough; a sketch or a spreadsheet you already use is even better.
2. Within 24 hours you get a one-page build plan: the views, the fields, and the delivery date. Nothing is charged until you approve it.
3. Pay the $100 with the PayPal button on this page. The first working draft arrives within 7 days.
4. Two revision rounds, then the final file lands in your inbox with a quick-start guide.

GOOD FITS

• A tracker for something no app covers: a medication schedule with your exact doses, a small farm's feed log, a club's dues ledger
• A planner that matches how your business actually runs: jobs, quotes, invoices, mileage, all in one place
• A personal dashboard that replaces three subscriptions
• A tool for a team or a family that must work without wifi and without accounts

WHAT IT IS NOT

No servers, no logins, no sync between devices, no app-store submission. It is one file that you own and can copy anywhere. If you need multi-user cloud software, this is the wrong product and we will say so in the build plan.

THE FINE PRINT

$100 covers up to 6 views and two revision rounds. Larger builds are quoted in the build plan before anything is charged. You receive the source file and may use it, copy it and modify it freely. Support by email: hello@browserhub.app.
