About

Vela

Features
Read full description

Vela helps you track perimenopause symptoms in seconds, notice patterns in your own data, and prepare for more focused conversations with your doctor. Perimenopause can feel confusing: sleep changes, mood shifts, hot flashes, fatigue, cycle changes, brain fog, and symptoms that come and go. Vela gives you a calm place to record what you notice and turn scattered days into a clearer personal summary. What you can do with Vela: โ€ข Log symptoms, mood, energy, sleep, triggers, notes, and period context โ€ข See your recent history and longer-term patterns โ€ข Prepare a doctor-ready summary for appointments โ€ข Track what changed without needing an account โ€ข Keep your health notes organized on your device Vela is designed for reflection and preparation, not diagnosis. Your logs can help you remember what happened, spot patterns you may want to discuss, and walk into appointments with a clearer picture of your experience. Vela Premium unlocks longer history, deeper insights, appointment prep, and doctor-ready report exports. Vela is not a medical device and does not provide medical advice, diagnosis, or treatment. Always speak with a qualified healthcare professional about symptoms, treatment decisions, or urgent concerns. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

SymptomLog and Vela are too close to call on the numbers: across 5 compared parameters โ€” price, ads, in-app purchases and device support among them โ€” neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
