About

Vela

Features
Read full description

Vela is the perimenopause tracker built around the moment it actually happens. One tap logs a hot flash or night sweat as it hits — timestamped, as many times a day as it comes — and your calendar heat-map shows where the episodes cluster, so you can finally see the shape of what you're living through. Vela is honest about your cycle. Instead of pretending to predict a date, it names what irregular actually looks like: "your cycles now range 26–41 days." In perimenopause the widening itself is the signal worth watching, and Vela says so plainly — no false precision, no alarms that something is wrong. When you're ready to talk to your clinician, the Doctor Visit Brief turns your logs into a clear, structured summary: hot-flash frequency and trend, your cycle's real range and stage read, what seemed to help, and the questions worth asking — built for the 12-minute appointment and for having the HRT conversation on your terms, with your own evidence in hand. Logging takes seconds: hot flashes and night sweats as they happen, mood, energy and sleep, brain fog, rage, aching joints and the other companions of the transition, plus period starts. Read calm, science-backed lessons on what's happening in your body — every clinical claim cites its source, anchored in NICE and Menopause Society guidance, written to inform, never to alarm. The safety layer is free forever: a crisis-support banner with real helplines that is never behind the paywall. All logging, the calendar heat-map, current trends, your first full insight and the pattern quiz are free. Vela Plus adds your full history across stages, complete pattern narratives with the numbers behind them, PDF export of the Doctor Visit Brief, and the full lesson library — as a subscription with a free trial. Your data stays on your device. No account, no ads, no third-party analytics. We never see what you log — so it can never be sold, shared, or leaked by us. Vela offers education and self-tracking. It is not a medical device and does not provide medical advice; it never tells you whether hormone therapy or any treatment is right for you — that is a conversation for you and your clinician. If you are in crisis, free support resources are always shown in the app. Vela Plus is an auto-renewable subscription: $4.99/month or $29.99/year, with a 7-day free trial on the annual plan. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage or cancel anytime in your Apple Account settings.
