You can use Chronicle Cloud (currently iOS only) to share bills with a partner.
If you’d like to sync your data with multiple users, for example, with a partner, just sign into the same Chronicle Cloud account on each device that would like to sync. Note that each individual user will need to purchase Chronicle Pro. However, one Chronicle Pro purchase works for all personal devices. So, for example, if Dustin has an iPhone and iPad, and and Suzie also has her own iPhone and iPad, and they want to share bills, Dustin will need to purchase Chronicle Pro once, and so will Suzie. They can both sign into the same Chronicle Cloud account, and bills will sync between all four devices.
