Six seasonal battles worth settling before winter — heating bills, holiday logistics, and the paperwork this time of year always brings. Every one runs free in your browser.
Before the first cold snap, see which heating system really costs less per delivered kWh — not just which sticker is cheaper.
Weigh the weeks of oil left against the delivery lead time, so you reorder before the tank runs low and prices climb.
Flag the month the heating bill stopped making sense, and leave with the numbers to question it.
Match the gathering table plan against the real guest count before the RSVPs close and the seating scramble starts.
Work out who gets which holiday for the next few years — and put the pattern in writing before anyone forgets it.
Turn this season's election dates into a personal action plan before the registration deadlines slip past.
The shelf rotates with the seasons, but the whole catalog is open year-round — browse all free tools or read the guides behind them.
Showing all 12 showcase apps.
Work backwards from the last frost date so sowing, ordering and hardening off land on time instead of the night before.
Paste the term dates and watch the board count back through every shopping step, marking the ones already behind.
Convert each opening’s measured perimeter into the packs of seal the job actually consumes — before the third trip to the shop.
Turn a sealing quote into months-to-payback, so two quotes can be compared on the same footing before either is signed.
Price the meeting before you book it: attendee cost, cost per decision, and whether the email would have been cheaper.
Compare each week’s logged billable hours against your utilisation target and flag the weeks past your tolerance.
Place homework into the evening window you really have, then see whether it fits before the argument starts.
Count the working days your notice really holds — weekends out, your holidays out, end date exclusive.
Paintable area, litres per coat and tins to buy, with the leftover shown before you order.
Wattage, daily hours and your own tariff in; annual running cost and replacement payback out.
Total the bag against your allowance, price the overweight fee, and name the items worth moving to carry-on.
Compare pack sizes by unit price, so the big pack only wins when your household’s usage says it does.
Every card is a real page in the catalog, and the shelf rotates with the season: the autumn toolkit stages six more seasonal battles, while the archive holds all 1,420 free tools.
The season dial · interactive
A patch of weather you can touch. Move your pointer through the scene to part the drift, tap anywhere to throw a burst into the air, and turn the dial to winter to frost the whole page — the header rule, the showcase glass, the seasonal palette and this sky all change together.
0leaves sent up
Autumn is live: golden leaves, embers and long evening light. Move your pointer to stir the air, or press Send a gust.
The scene is drawn in your browser and never fetched; the only thing remembered is which season you picked. Prefer keys? The two season buttons and Send a gust do everything the pointer does. The seasonal showcase and the autumn shelf stay real tools either way.With reduced motion on, the scene holds still and the buttons still change the palette.
The same catalog, read as a status board. Twelve companion apps — Autumn Specials, Cloud Utilities and Live Edge — each showing the live metadata that sits in live-matrix.json: how many people are on it, how fast it answers, which catalog generation built it, and whether its verification is current. Filter the shelf, search it by name, or sort it by whichever number you care about. Every card opens the real tool.

Synthetic telemetry, stated plainly: the active-now and latency figures are simulated in your browser from a fixed seed, and the sparkline is that same simulation. Everything else on these cards is the real catalog record — name, life area, version, verification date and price — read from live-matrix.json, which tools/home/build_live_matrix.py builds from metadata.json. Latency is modelled from the byte size of each app page.
Twelve of the 12 apps on the live shelf are also photographed in the seasonal showcase; the rest were picked for the shelf. The full catalog of 1,420 free tools lives in the archive.
