Cross-platform support (iOS and Android)
You can take your backup from iOS to Android or vice versa. For more info see: How to transfer backup between platforms
iOS or Android do not allow transferring any purchases between platforms so you need to purchase it separately for each system. Daylio uses official Google and Apple stores. They have your payment options and charge you money for apps and services. We do not receive the money directly from you, we are paid by Google and Apple. We know this sucks, but we hope you will still enjoy using the app on one of the devices.
