## What is Nelbi?

When did your period start? How long did it last? How have you been feeling, physically and emotionally?

Nelbi is your period tracker and personal body diary. With a little cat by your side, keep a record of each month and make time to check in with yourself each day.

• Period records that are easy to revisit
Log when your period starts and ends, and see each period on the calendar. Add entries you missed or correct dates whenever you need to, keeping your history up to date.

• Your body and mood, in one diary
Record flow, symptoms and their severity, along with moods, discharge and daily activities. From cramps and tiredness to a particularly happy day, save how you feel and add your own notes.

• Look back with clear charts
View cycle lengths, period durations and changes over time. Explore your flow, symptom and mood records. Recent statistics and yearly overviews bring your daily entries together, making them easier to understand and compare.

• Log from your wrist
Sync between iPhone and Apple Watch. Check your calendar and log period starts and ends on your watch. After the first sync, you can save period entries offline on the watch and send them to your phone when connected again.

• A little cat to keep you company
Open the app to see your cat, and tap to interact. Choose between Blossom Pink and Midnight Violet themes. Set a daily logging reminder to help you remember your check-in.

• Your personal records, under your control
No account required. Health records stay on your device and are not uploaded to the developer's servers. Enable the privacy lock to protect your records with device authentication. Reminder notifications do not show specific period dates or body diary entries.

• Export, back up and organize
Export period and daily records, create a summary, and choose whether to include personal notes. Back up and restore your data. With your permission, you can also write period records to Apple Health or select existing records to import.

Start with today, and give yourself a record to look back on.
