Olla Period App
Read full descriptionHide full description
Olla is a private period and symptom tracker that lets you track your health in your own words. Instead of filling in endless forms, simply tell Olla what happened. Log your period, spotting, hot flashes, cramps, headaches, mood, sleep, energy, HRT, medication, pain, or anything else you want to remember. Olla turns what you log into a personal health journal you can explore over time. See when symptoms happened, how often they occurred, and how they changed across days, months, periods, and cycles. Compare anything you track to look for patterns in your own data. Ask Olla questions about your history, such as: - When did I last have a headache? - How often have I logged hot flashes? - Did I have more hot flashes before or after changing my HRT? - How does my sleep compare with my period days? - What symptoms have I logged most this month? Olla is especially useful when your cycle isn't predictable. It doesn't require your body to follow a 28-day cycle, making it useful for irregular periods and perimenopause tracking. Set reminders for anything you want to remember, then check them off in your journal. PRIVATE BY DESIGN Your health data stays on your iPhone. No account. No cloud database. No advertising trackers. Your period and symptom history is yours. Under strict GDPR rules! WITH OLLA YOU CAN ⢠Track periods and spotting ⢠Track symptoms in your own words ⢠Keep a daily health and symptom journal ⢠Track perimenopause symptoms ⢠Log HRT and medications ⢠Track sleep, mood, pain and energy ⢠Compare symptoms and other things you track ⢠See symptom patterns over time ⢠Ask questions about your logged history ⢠Set custom reminders ⢠Review your cycle and period history No rigid symptom checklist. No assumption that every cycle is the same. Just tell Olla what happened and build a useful record of your own body over time.

Verdict
The clearest difference is update cadence: Olla Period App at every 3 days against CalmFlow's every 3 months. CalmFlow's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.5). On price, ads and in-app purchases there is nothing between them.
