As long as you still have your old phone with you, it'll be easy to migrate everything over. On your old phone, you can click the menu button (three dots in the top right corner) and then select "Backup". Send this SmartReceipts.SMR file to your GMail/Dropbox/etc account. This file is actually just a big ZIP file, but I changed the extension, so other apps don't try to open it by accident. After you've installed smart receipts on your new phone, tap on this file to open it and begin the import process. You can also select the backup option again and click the import button directly from there. Longer term, we're building a cloud backup infrastructure, so this process will be automatically managed.
