Reckoner is a personal finance tracker for people who want to record everyday transactions without transferring their financial history to a commercial service. It treats the user’s data as private information and provides flexible ways to interpret it. Rather than forcing a single accounting workflow, Reckoner lets you organise transactions according to categories, tags, or a combination of both.
Its customisable reports let you select the information you want to see, such as recent spending associated with a tag or the amounts allocated to different category groups. Limits can be applied to categories, making it possible to maintain several spending plans at once. The approach is intended to suit both people who budget closely and those who simply want an accurate financial record.
Reckoner stores financial records locally. An optional synchronisation arrangement uses end-to-end encryption, allowing users to keep data consistent without exposing its contents to an intermediary. For desktop use, the developer now emphasises the progressive web application; native Linux builds are no longer the preferred route.
This is free and open source software.
