Focused software, built in Belgium.
PurpleGreen builds software for organisations that deserve better tools than the generic ones. Each product does one job well, respects the people who use it, and runs in Europe.
Products
MartialBook
The all-in-one app for martial arts clubs: attendance, ranks and belts, kids' progress booklets, plans and payments, with apps for students and parents.
Daedalus
Time tracking that remembers for you
On your Mac, Daedalus follows your git commits, project folders and AI coding sessions such as Claude Code and Codex, and proposes the day's time entries for you to confirm. Optional AI summaries run on your Mac with Apple Intelligence or Ollama, or with your own Claude or ChatGPT key. Parallel timers, customers and billing codes, on Mac and iPhone. Your data stays on your own devices and iCloud; nothing is sent to PurpleGreen.
purplegreen MDM
Every kiosk, one dashboard
Manages fleets of company-owned Android tablets that run as unattended kiosks: self check-in, point of sale, signage, visitor registration. Enrol a tablet by scanning a QR code, lock it to one app, and watch every device from one dashboard: online status, battery, app version, and remote reboot or wipe when something goes wrong.
How we build
Security first
Founded by a cyber security consultant. Security is part of the design, not a feature added later.
Hosted in Europe
Our services are hosted in Europe, under European privacy law.
Made for one job
No bloated suites. Each product is built around how its users actually work.
