The name

Tankbook – one word, capital T. The site is tankbook.live.

One-paragraph description

Tankbook is a car cost log for iPhone that keeps your data on your phone and works with no account. Fill-ups, charging, service and the rest are added in seconds through two equal doors – snap the receipt, or type it in – and every entry is checked by arithmetic you can watch: litres × price has to equal the total. It reads petrol, diesel, hybrid and electric cars in one history, keeps both amounts when you fill up abroad, exports everything in CSV or JSON for free, and never asks you to sign in first.

Facts

Price: free; nothing is for sale today.
Account: not required. Optional sign-in enables sync and restore.
