@ColinUK Here’s the reply I got back from Carbs & Cals:
*************************************************
The food diary does not currently automatically sync between devices, but this is something we are hoping to introduce in the future.
If you have large batches of data you want to move across you can do a backup of one device and restore it to the other.
Please follow the below steps:
On the device you wish to copy the plan from:
1) Tap on the profile icon (top right on home page).
2) Tap on Backup & Restore
3) Tap the green button ‘OK, start backup’
4) Enter your first name and email that you want the backup key sent to.
5) Agree to terms, decide if you wish to sign up to the newsletter
6) Tap on the green button ’Send Backup Key’. You will receive an email containing the key
On your new phone / tablet you wish to add (restore) the plan to. This will also copy across the diary data and any custom foods and meals from the primary device.
Install the app on the free Starter Plan.
1) Tap on the profile icon (top right on home page).
2) Tap on Backup & Restore
3) Tap the white button ‘Restore a backup’
4) Enter the backup key and tap the green button ‘Restore Backup’
Important points to note:
• Please do not exit the app whilst the backup or restore are running
• If the backup or restore runs for more than 5 minutes, you may want to quit the app and try again
If you do experience any problems or have any questions about the steps please get back in touch.
Please let me know if you have any further questions.
