To keep one on your phone: open it, press the
Share button at the bottom of Safari, then Add to Home Screen.
It then opens like an app, full screen, with no address bar.
Every price is on this page, before you start. Each app
is free for the days shown, then you own it — paid once, or in the instalments
shown on its card. Never a subscription, and never a charge you didn't see on
this page.
Bought one already? Open it here, then paste the
licence key from your receipt email. It is checked once and then the app
never contacts anything again.
