How do I login my iPhone / iPad?

Are you getting the’ Visit SketchAndCalc on the web’ message?

The temporary solution is to login on the webapp via a desktop browser and then choose ‘Logout’ from the main menu.  Returning to iOS you’ll now be able to login without the error message.

Unfortunately Apple have blocked recent updates to the iOS app, so the legacy version in the store is missing the ability to communicate its status with our server.
