Your symptoms deserve more than a guess. peri is a private menopause and perimenopause tracker that helps you record how you feel, follow treatment changes, and prepare for your next appointment. Keep hot flashes, night sweats, sleep, mood, HRT, medications, and notes together in one on-device record. No account needed. An active monthly or annual subscription is required; there is no free tier or free trial. TRACK HOW YOU FEEL Build a daily symptom journal with a focused check-in. Record symptoms, sleep, mood, movement, weight, and notes. Confirm each day so your history reflects what you actually logged. SEE YOUR PATTERNS Review symptom days and treatment changes together in Journey. Calendar-based weekly summaries help you see how your record changes over time, without claiming to diagnose a condition or prove what caused a symptom. KEEP HRT AND MEDICATIONS IN CONTEXT Log hormone therapy, other medications, supplements, schedules, doses, and lab results. Record treatment changes and structured 2- and 6-week follow-ups. Stop or archive a treatment while keeping its history. PREPARE FOR YOUR NEXT APPOINTMENT Save the questions you want to ask and capture your clinician's plan afterward. Create a 30-, 90-, or 180-day report with symptoms, treatments, labs, and notes, so you have a record to discuss instead of relying on memory. MAKE CHECK-INS EASIER TO REMEMBER Choose generic reminders, privacy-safe Home Screen widgets, and App Shortcuts that help you return to your daily record. OPTIONAL APPLE HEALTH SUMMARY When you choose to connect, peri reads step, sleep, and latest body-weight data on-device to calculate the displayed summaries. Access is read-only, never runs in the background, and never writes to Apple Health. EVIDENCE WITHOUT THE HYPE Use an evidence-graded reference library covering menopause symptoms, treatment options, sleep, mood, sexual health, bone health, and more. Sources and uncertainty are shown clearly. PRIVATE BY DESIGN Your health record stays on your device. The iPhone and iPad app encrypts its local record with a device-bound key, offers Face ID App Lock and password-protected backups, and never sends health entries or Apple Health values to analytics or attribution services. There is no account, cloud health database, sale of personal data, or third-party advertising. ONE SUBSCRIPTION, EVERY FEATURE peri requires an active auto-renewable monthly or annual subscription. There is no free tier or free trial. The exact price is shown before purchase, and payment is charged to your Apple ID at confirmation. Your subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple ID subscription settings. Privacy Policy: https://menlopass.vercel.app/privacy.html Terms of Use: https://menlopass.vercel.app/terms.html peri provides general health education and self-tracking. It is not a medical device and does not diagnose, prescribe, or replace care from a qualified clinician.

Verdict
The clearest difference is in-app purchases: Herflow at none against peri's 2. Herflow also leads on ads (none vs shown) and update cadence (daily vs every 4 days). On price, device support and iOS requirement there is nothing between them.
