Yes. If you have past data in Huckleberry, you can export it as a CSV file and import it into Kiri from Settings. That makes it easier to bring older history with you instead of starting from zero.
Step 1: export the CSV from Huckleberry
Open the Huckleberry app.
Go to Settings.
Choose the CSV export option.
Open the email with the file and save the CSV to your phone, usually in the Files app.
Step 2: import the file into Kiri
Open Kiri.
Go to Settings.
Tap Import Huckleberry Data.
Choose the CSV file you saved and start the import.
What happens during import
Kiri imports the file row by row.
If you import the same file again, Kiri will dedupe matching rows instead of blindly duplicating everything.
That means it is okay to re-import if you are not sure whether a previous import finished.
What may be skipped
Some Huckleberry categories do not have a direct Kiri equivalent. For example, baths are not a Kiri entry type today, so those rows are skipped.
