How it is made
One person, one standard.
Made by one person
Every app is designed, written and supported by the same developer, so it is always clear who is accountable.
Finished before it ships
A feature appears on an app's page only when it is in the app today. No roadmaps sold as products.
Your data stays yours
Apps keep your work on your own device, in files you can find and back up.
The maker
Around fifty years in software.
StratumCode is run by Theo van Stratum: a doctorate in Information Technology and a career across the United Kingdom, Europe, Australia and Asia.
