Made to feel
straightforward.
What does Calla track?
Calla is an iPhone diary for perimenopause and menopause symptoms, hot flashes, night sweats, sleep and hormone replacement therapy (HRT). Record how you feel, log medication doses and keep a history for your next appointment. It works without an account, and your health entries stay on your device.
Can I track HRT and share a report with my doctor?
Yes. Add your hormone therapy schedule, set medication reminders and log dose changes. Calla Pro adds before-and-after symptom observations when enough days are logged and lets you create a PDF report to share with your clinician. Calla does not recommend medicines or doses.
Can I use Calla if I don’t have periods?
Yes. Whether you’re in perimenopause, past your last period, using an IUD or have had a hysterectomy, you can track symptoms and treatment without logging a cycle.
What is included without a subscription?
Daily logging, your saved entries and JSON/CSV data exports. Calla Pro adds insights and new PDF reports. Ending a subscription never removes your entries or stops raw data exports.
Do I need to connect Apple Health?
No. Apple Health is optional. You choose which data types Calla can read or write. HealthKit entries are excluded from Calla’s iCloud backups.
Does Calla give medical advice?
No. Calla helps you keep a record and notice patterns. It does not diagnose conditions or recommend treatment or doses. Your clinician is the right person for those conversations.
Where can I download Calla?
Calla is available now on the App Store for iPhone with iOS 16.4 or later. Download it and start your journal without an account. Daily logging is free; Calla Pro is an optional subscription for insights and PDF reports.
