Focused
A clearly defined problem, an understandable workflow, and features that genuinely help with everyday work.
Independent software · Austria
Apps that make work easier.
Darkstone builds focused tools for real, recurring workflows — from cash closing to presenting to tournament nights. Clear in scope, calm in use, and sparing with data.
Independently developed in Lower Austria · iOS & Android
How we think about products
Less clutter. More reliability.
Software should make a workflow easier to understand, not create a new layer of administration.
Private by design
No unnecessary account, no advertising, and no developer analytics. Your data stays as close to you as possible.
Fairly priced
A useful free core and transparent, optional one-time purchases instead of artificial subscription pressure.
Darkstone apps
Four tools. Four clear workflows.
Each app focuses on a specific task, remains useful without a mandatory account, and explains transparently what happens to data.
