iPhone Duo support.

Fixes a problem where Liquid Glass buttons on the Chart screen did not appear correctly;

In response to user feedback, I've added a watchOS app which allows you to add records conveniently using your Apple Watch. You can also view the last seven days of data on your watch.

- It's now quicker to change the volume of material when editing records. - Buttons for changing graph dates are now smaller.

- Date range for charts is now a moving 30 day window. - Changes to the chart date ranges are now animated with a smooth transition. - Added "Settings" tab which allows you to delete old records and reclaim storage space on your phone or in iCloud. - Adding headings to the "Charts" tab to prevent charts overlapping with the device's status bar.

- Small fix for charts which previously drew some bars outside the expected area when you had lots of data saved. - Default view for charts is now 30 days, rather than all records. - Added German localisation.

Added a chart for volume of material. Added a calendar view showing dates with records. Increased padding around charts for easier readability.

Added a fix for slow performance when the app has a large number of records with images.

When viewing saved photos you can now pinch and zoom to inspect them in more detail.

New lock screen widget allows quick and easy access to the app. Fixed a bug affecting the way category 1 stools appeared in the list.

Your data now syncs with and is backed up to iCloud, meaning you can access your records from all your iOS devices. It's now clearer to see where your newly created record has been added to the list of existing records.

Records are now listed in reverse chronological order, so that your most recent records are at the top of the list.
