PocketKit
Every little tool, one pocket.
PocketKit brings the small, everyday tools you keep reaching for into one clean app — a discount calculator, an everyday calculator, a tip splitter, a BMI tracker, a rent book, a vehicle log. It's local-first: no account, no cloud, no sign-up. Everything you enter stays on your device, and every tool works fully offline.
What's inside
Discount calculator
Work out sale prices with stacked discounts and tax, instantly.
Calculator
A simple calculator with a persistent history tape.
Tip & split
The tip and what each person owes — and when the bill won't divide evenly it shows who pays the odd penny, so the shares always add up.
BMI tracker
BMI with your goal weight and a weight-log chart over time.
Rent tracker
For both sides of a tenancy — what you pay and what you receive — with a clear due/overdue view.
Vehicle log
Service history, costs, and registration / insurance renewal dates, each shown as due soon or overdue.
Settings
Light, dark or system theme — and everything you enter kept on your device.
