To sync your Timeframe data across Macs and iPhones, make sure you are running the latest version of Timeframe on all devices.
Once Timeframe sync is enabled, your data is synchronized automatically. Under normal conditions, using the “Force sync” button is unnecessary.
Also, please consider these details:
Make sure iCloud Drive is enabled.
On the Mac, this setting is found in macOS System Settings > Apple ID > iCloud.
On the iPhone, it is found in iOS Settings > AppleID > iCloud.
If you are logged into iCloud and iCloud Drive is enabled, but Timeframe doesn’t want to connect to iCloud, reboot your device. This can fix iCloud sync problems.
To be in sync with other devices, ensure you are using the same iCloud account on all devices.
For the sync to work properly on the iPhone, make sure Notifications are enabled for Timeframe (Settings > Notifications > Timeframe > Allow Notifications).
There is no need to install and run the Dropbox app on your Mac. You just need a Dropbox account. If you don’t have one yet, create a Dropbox account here. It is free for up to 2 GB of data.
Please note that using a VPN internet connection with Dropbox sync can sometimes lead to sync problems. If Timeframe sync gets stuck, changing your DNS server settings (for example to Google’s DNS servers) usually fixes the problem.
If you run into any problems enabling iCloud, Dropbox, or WebDAV sync, please email the developer at firstname.lastname@example.org or ask for help here in the community.
