Premise

A mantelpiece,
not a dashboard.

A mantel is the shelf above the fireplace — the place a family keeps photos, candles, and the things that matter. The product takes that as its premise. Not a productivity tool. Not a smart-home controller. A warm, shared surface in the home.

Warm

It belongs next to family photos, not next to a thermostat. Nothing on screen is cold or clinical.

Calm

Information at a glance — never demands. The brand should lower a heart rate, not raise it.

Trustworthy

Reliable like a clock on the wall. Always on, always accurate, always there.

Features

Everything that runs the family,
on one wall.

Nine surfaces, one app. Each one synced bidirectionally with the Google service the family already uses.

See it on the wall
Google Calendar

Calendar

Day, week, and month views with family color-coding. Two-way sync with every Google Calendar in the household.

Google Tasks

Tasks & chores

Per-member boards, due dates, repeat metadata. Anyone can swipe to mark done.

Google Tasks

Shared lists

Grocery and to-do lists everyone in the family can edit live from any device.

Google Photos

Photo screensaver

Pick a Google Photos album. Idle triggers a slow crossfade slideshow with the clock overlay.

Google Drive

Recipes

A folder of Google Docs becomes a searchable cookbook. One Doc per recipe — own your data.

Google Sheets

Meal plan

Weekly grid backed by a Google Sheet. Drag a recipe onto a slot; the wall shows tonight's dinner.

Google Sheets

Piggy Bank

Earn / spend / save / give buckets per child, with savings goals and clear transaction history.

Google Sheets

Reading & garden

Track minutes read or plants watered. Spreadsheet-backed — extend with any new tab.

Synthesized

Daily briefing

A morning summary: weather, today's events, chores, and family birthdays — surfaced once.

Wall + phone

Plan on the wall.
Tweak from the couch.

Mantel is the same PWA on both. Glanceable from across the room at six feet, tappable from your pocket. Add a grocery item from the car, see it appear on the kitchen wall by the time you're home.

1920×1080 wall view

Sidebar + main, 84px clock, no header chrome. Designed to be read from 6–8 feet away.

Mobile companion

Bottom tab bar, FAB quick-add. Same data, same Google account, scales to a 390px screen.

Auto-dim at night

A CSS filter quietly dims the display after sunset so the screen never glares in a dim room.

Your Google. Your data.

Google is the backend.
You own every byte.

Mantel is a thin, pretty layer over services your family already pays Google nothing extra for. No proprietary database. No vendor lock-in. Cancel Mantel and your data is still right there in Google.

Bidirectional sync

Edits on the wall flow back; edits in native Google apps flow forward.

Offline-first cache

IndexedDB keeps the last sync. Pending writes queue and replay.

No backend, no server

Static site on GitHub Pages. Nothing to host. Nothing to expire.

Always a fallback

Cancel anytime. Native Google Calendar / Tasks still work the same.

Pricing

One price. Forever.

No subscription, no account, no upsell. Self-host on GitHub Pages and that's the bill.
