If you’ve made a backup copy of your app data (see Backing Up the Kinsa App), you can use that backup to transfer the Kinsa app data from your original device onto another device running the same OS. There are many articles online that can help with this - choose your favorite! Try Googling “Restoring Android/iOS data” and reading a few articles. For Android you may need to include the OS you are running for best results.
