KMySync

Mobile companion for KMyMoney — record cash expenses on the go
New in version 2.3
New: bookings from push notifications – for banks without FinTS. KMySync learns from a booking you enter by hand and, on refresh, suggests future transactions as a list, with payee, category and location.

New: read and write the KMyMoney database (SQLite).

Safer export: self-check after every write, line-by-line comparison, restore on errors.

Backups: adjustable number, permanent monthly backups.
KMySync is a mobile companion to the desktop finance software KMyMoney. Record cash expenses, income and transfers on the go, keep track of your portfolio, and write it all back into KMyMoney instead of typing it in by hand later.

The app needs no vendor account and no third-party cloud: data is exchanged with KMyMoney through a folder you provide yourself (WebDAV, Nextcloud or SMB/Samba). No ads, no tracking.

One exception to that: the optional map on which you pick a location loads its tiles from OpenStreetMap. It is the only screen that contacts anything other than your own server, and it opens only when you open it.

Features:

* Seamless KMyMoney integration via .kmy files or CSV import
* Several profiles — keep several KMyMoney files side by side
* Sync through a shared WebDAV or SMB folder — your own server, your data
* Charts and analysis per account, place or total
* Portfolio with holdings, latest price and net worth
* Record transactions for securities you already hold — buys, sells and dividends, including optional PDF recognition of the statement
* Fuzzy voice entry with optional location-based payee suggestion
* Multilingual — English, German and Spanish built in, more languages via upload
* Biometric lock and encrypted credentials

On the PDF recognition: the app reads the statement's text layer, recognises the security, the date and the amounts, and learns per bank and portfolio where those values sit in the document. It does not work with every bank — scanned documents are out of reach, and unusual layouts can escape it. It is off by default and is switched on in the settings.

Note on this F-Droid build: it is the phone app without Google Play Services. The optional Wear OS companion (voice entry from a watch) requires the Google Wear Data Layer and is only available from the project's GitHub releases: https://github.com/PerFermat/KMySync/releases

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.

  • New in version 2.2
    New: sync mode "Read .kmy, export CSV" – accounts, schedules and portfolio come from the KMyMoney file, writing happens via CSV only.

    Safer export: stops if KMyMoney has the file open; self-check before upload; no duplicate bookings after a crash; file encoding is checked.

    Editing exported bookings, split bookings, advancing schedules and portfolio entry are available in .kmy mode – CSV cannot represent them.

    Watch: more reliable voice input.
