Four transformations on the natal chart, the decadal and annual layers, and a transform-by-transform reading for each topic: wealth, career, partnership, opening a shop, love, friends, children and more. A year that does not touch a topic is left out instead of being padded with a generic line.

Open Web app in Safari, tap Share → Add to Home Screen. It then behaves like an installed app and works offline after the first load.

This is the offline edition: there is no online checkout and no account login. Charts and the core reading are free. To unlock every formula, open Settings → Licence, copy the Device ID and send it to the author; you will get an activation code that binds to that device.
