"App installation is prohibited at this site..."
No Installation Required (Web App)
Security conditions at training venues are often very strict. No matter how much time you spend preparing, it is meaningless if the app cannot run on-site.
Use the web version with no installation required in environments where installing apps is restricted
Import presets and settings via the clipboard in environments where file handling is blocked
No annoying ads at all!
