Everyday Utility Tools
Five small everyday tools: compare shelf prices per unit, split an unequal bill down to the item, estimate the mobile data a month needs, plan document renewals, and print a wallet emergency contact card.
About these tools
Small domestic calculations rarely deserve an account, an app or an advert-heavy page. These five do the arithmetic that actually decides something - which pack is cheaper per kilogram, who owes what after dinner, whether your data plan survives the month, when your passport stops being accepted - and then get out of the way.
The two tools that touch personal information, the document expiry planner and the emergency contact card, keep everything in the browser tab, store nothing by default and warn you before any export leaves your device. The data-usage figures are transparent, editable assumptions rather than measurements of your phone.

All Everyday Utility Tools
- Unit Price Comparison Calculator Compare shelf prices honestly: convert every pack to the same unit - per kilogram, litre, 100 g or item - handle multipacks and promotions such as three for two, and rank them by what you really pay per unit.
- Unequal Bill Split Calculator Split a bill that was never equal: assign items to the people who had them, share the rest, apportion service charge, tax and tip in proportion, then see the shortest set of payments that settles everyone up.
- Mobile Data Usage Calculator Estimate how much mobile data your month actually needs: streaming, video calls, music, social and browsing at rates you can adjust, the daily allowance a plan gives you, and the day your allowance runs out at this pace.
- Document Expiry Planner Keep track of documents that expire: expiry dates with the lead time each renewal needs, a warning when a passport falls inside a destination's six-month validity rule, a sorted timeline, and calendar reminders.
- Emergency Contact Card Maker Make a wallet-sized emergency card: contacts, blood group, allergies, medication and insurance details, laid out to print at the right size, exportable as a vCard, and built entirely in your browser with nothing stored.
