Mendbook
A passport for your belongings: purchases, warranties, repairs.

Who it is for
Owners of devices and things who decide whether to repair or replace.
What it does
Item cards with purchase date, price, warranty and service history, check reminders, and a monthly-cost comparison between repair and replacement. Data stays on your device and the app works offline.
What you get
A local item passport, reminders and a JSON backup.
Limits
The repair-versus-replace figure is indicative: it ignores downtime, convenience and disposal.
