Newly added tools

These ten landed after a full audit of the catalogue. Each one fills a gap that wasn't covered — picked because the subject area was completely empty, not just thin.

The ＋ on any card saves that tool into your toolbox — a private shortlist kept in this browser, no account, and the whole catalogue is filterable here →

📝 What was added (Sept 2026)

Rather than guess, all 552 existing titles were dumped and ten subject areas probed for coverage. Three looked covered but were false positives (walking pace was a step-counter, cadence was wing-beat, aperture was astronomy). The other ten were genuinely empty — so here they are.

3 in Science & Engineering, 2 in Health, 2 in Finance, 2 in Productivity, 1 in Home & DIY.

🥾 Just added

Hike Time Planner

Naismith's rule + Langmuir descent correction + real sunset times from your latitude. Tells you whether to start at dawn or take a head torch.

Home & DIY
🚴 Just added

Bike Gear Calculator

Gear inches, development, gain ratio, wheel duplicates, speed at cadence — the four numbers that actually matter when choosing gearing.

Health & Fitness
📷 Just added

Photo Exposure Lab

EV equivalence across stops, ND filter exposure, true depth of field (not the marketing version), and the diffraction limit at your aperture.

Science & Engineering
🏃 Just added

Race Pace Predictor

Riegel formula predictions for any distance, plus five training paces derived from a recent race time. Honest, not optimistic.

Health & Fitness
👶 Just added

Baby Sleep Planner

Wake windows → nap length → bedtime, by age band. A plausible shape for the day, not a guarantee — because no two babies are alike.

Productivity & Lifestyle
⚡ Just added

Energy Tariff Comparator

Annual cost comparison across tariffs, plus the exact usage level where the ranking flips. Useful for variable / off-peak deals.

Finance & Money
🛒 Just added

Unit Price Comparator

Normalises multi-pack offers to a single comparable number — per 100g, per sheet, per load. Finds the bigger pack that's actually more expensive per use.

Finance & Money
🔤 Just added

Fluid Type Scale

CSS clamp() solved from two breakpoints and a base size, in rem. Picks the right min/max so type looks good at 360px and 1920px.

Productivity & Lifestyle
🧵 Just added

Fabric Yardage Estimator

Width, nap direction, pattern repeat, and pre-wash shrinkage — folded into the total yardage in the right order, so the bolt you bring home is enough.

Science & Engineering
🚗 Just added

Car Care Tracker

MOT + service countdowns, tyre-tread wear projection, and cost-per-mile derived from your actual receipts — not from a guess.
