Frequently asked questions
Everything you need to know.
Yes — Hemo is a daily health companion built specifically for Sickle Cell Disease. It helps you log symptoms, track patterns over time, manage care details like medications and contacts, and walk into every clinic visit with real context instead of relying on memory.
Hemo's guided daily log captures pain level, body location, mood, hydration, sleep, and possible triggers in one short flow. Over time those entries build a visual history, so you and your care team can see when pain crises cluster and what tends to precede them.
The guided flow brings pain, mood, hydration, sleep, triggers, and notes together. Take the time you need and return when you can. Follow your care plan and seek care when needed before recording an entry.
Hemo supports all major types — HbSS, HbSC, HbS-β⁰, HbS-β⁺, HbSD, HbSE, and more. If you're unsure of your specific type, you can still use Hemo and update that detail later from your profile once you know it.
No. Hemo is a tracking and preparedness tool, not a medical device or emergency service. In an emergency, contact local emergency services immediately. Hemo does not dispatch emergency help or confirm message delivery. Follow your care plan and contact emergency services directly when you need urgent help.
Hemo is built with a privacy-first approach. Your health data is stored securely and is never sold or shared with third parties for advertising. You control what you log, and full details on how your data is handled are on the Privacy page.
Hemo’s private beta is live on iPhone, and applications are open. Access is by invitation. Android is paused for now and remains planned. You can apply for the iPhone beta, subscribe to Android updates, or sign up separately for general launch updates.
