What it does: A local-first, peer-to-peer, zero-based budget on the Logos stack
Stage: Almost done
Licence: MIT or Apache-2.0
Verified on 4 November 2026 against README and commit of 10 October 2026.

KYM (Know Your Money) is a household envelope budget by the GitHub user vpavlin that syncs between its users' own devices over Logos Messaging (Logos Delivery, also called Waku). It has a Basecamp module for the desktop and an Android app, and the README calls it an alternative to the budgeting app YNAB (You Need A Budget).

What it does

  • It keeps a zero-based envelope budget, which gives every unit of income a spending category. By the README's account, it has no server and no cloud custody of the finances.
  • It syncs a household's budget directly between its devices over Logos Delivery. The README says the sync is end-to-end encrypted.
  • It holds several budgets at once. Each is its own household with its own secret, topic and event log, and is shared by showing its QR code or pairing code.
  • It records money as an append-only ledger, in which an edit is a new event and a delete is a marker event (a tombstone). Two people editing offline therefore end up with the same budget after sync.
  • Its desktop view in Basecamp (kym) runs over a core module (kym_core), and the same core can run headless, with no interface, under logoscore as an always-on hub.
  • Its Android companion app logs an expense quickly and reads photographed receipts with on-device OCR.
  • It includes a command-line budget with accounts, categories, targets, bank import, reconciliation and reports.

Stage: Almost done. The README's status says the engine, contract, crypto, merge and both module builds "are green and cross-checked". It ends with "Needs real hardware to finish", naming the phone's receive path and OCR accuracy on real receipts. It adds that the mobile Delivery transport is still being stabilised on real hardware. The README does not say whether it is an official Logos project.

Use it

  1. In Basecamp, open Settings, then Package Repositories, and add https://apps.vpavlin.xyz/logos-repo.json.
  2. Install the two packages kym_core (the core module) and kym (the view).
  3. For Android, install the APK from the F-Droid repository at apps.vpavlin.xyz. It is built for arm64 phones.
  4. To try it without Basecamp, run npm install, npm test and npm run demo in the repository, then drive a budget with node cli/kym.mjs.

The README does not name a Basecamp version.

Build it

  • npm install sets up the packages. npm test runs the engine and sync tests, and npm run demo shows two partners editing one budget offline and then syncing.
  • The Android APK is built and signed locally with scripts/build-apk.sh.
  • Releases are cut by pushing a module-v* tag, after which CI builds the portable .lgx and refreshes repo/index.json. The only tag so far is v0.8.0.

Releases

The latest tag is v0.8.0, dated 4 August 2026. module/metadata.json gives the kym view version 0.7.0, and kym_core/metadata.json gives kym_core version 0.8.1.
