Questions
Can I import my old data?
Yes — import daily egg counts from a spreadsheet or another app's CSV export (date, flock, number of eggs).
What if I change phones?
Make a backup file in one tap, save it to iCloud Drive, Google Drive or email, and restore it on the new phone. Photos are safe in the backup files you save.
What if the app stops being updated?
Your data never depends on our servers — there are none. Backup files and CSV export always work.
Does it give health or feeding advice?
No. Yolkbook records what you enter. Reference values such as incubation days are typical values and always editable.
