The sickle cell tracking app for pain, patterns, and appointments
Hemo is a sickle cell app built for people with Sickle Cell Disease (SCD) to track pain, hydration, mood, sleep, and medications in one place. As a dedicated sickle cell tracker — not a generic wellness app adapted after the fact — Hemo turns short daily logs into patterns you and your care team can actually use.
Think of it as a sickle cell pain diary app with the rest of day-to-day SCD care built in around it — medications, care team contacts, and appointment prep alongside your pain and symptom log. If you're looking for an app for sickle cell patients that goes further than a generic pain scale, this page walks through what Hemo does and how it compares to the alternatives.
What the app actually does
Six screens, one goal: make daily SCD tracking fast enough to actually keep up, and useful enough to change your next appointment.
Daily Log
A guided sickle cell pain diary, not a blank text box
Log pain level, body location, mood, hydration, sleep, and possible triggers in one short guided flow — built for real SCD days, including the hard ones.
Health Trends
Patterns across every metric, not just pain
Calendar and chart views for pain, mood, hydration, sleep, steps, and heart rate, with 7-day and 30-day toggles so patterns are visible instead of buried in memory.
Health Insights
This week vs. last week, in plain language
A weekly wellbeing score and plain-language callouts for what actually changed — context, not just raw numbers to interpret yourself.
Care Hub
Medications, care team, and crisis plan in one place
Medication list with dosage and frequency, care team contacts, crisis plan, and emergency profile — organised and reachable fast when it matters.
Streaks
A habit system that doesn't punish missed days
Daily streaks celebrate consistency, and a limited number of streak repairs cover the days you couldn't log — because consistency, not perfection, builds the useful history.
Home
Today's status at a glance
A home screen that surfaces what needs attention today — your streak, today's log status, and the metrics you're tracking — without digging through menus.
Hemo vs. generic symptom trackers vs. a paper diary
Generic symptom trackers and paper diaries both genuinely work for plenty of people — they're flexible, cheap or free, and don't require adopting new software. The honest difference is SCD-specificity: how much of the setup, structure, and reminders are already built around sickle cell management instead of left for you to invent.
| Criteria | Hemo | Generic symptom tracker | Paper diary |
|---|---|---|---|
| SCD-specific pain & crisis logging | Partial | Manual — you design the format | |
| Trigger tracking | Partial | Manual — easy to forget | |
| Hydration goals | Manual | ||
| Clinical summary / PDF export | Partial | The notebook itself |
"Partial" means the capability exists in some generic trackers but isn't built around SCD specifically (e.g. a free-text field instead of structured trigger tags). Pricing for generic trackers varies widely by app and plan.
Frequently asked questions
Everything you need to know.
Generic symptom trackers cover pain on a broad scale but aren't built around SCD specifics like crisis logging, trigger tags, or hydration goals. Hemo is a sickle cell tracker from the ground up, so every field in the daily log maps to how SCD is actually managed day to day.
For most people, yes. A paper diary works and costs nothing, but it can't chart trends, remind you to log, or export a clinic-ready summary. Hemo keeps the same idea — a daily pain and symptom record — while adding structure, reminders, and pattern tracking on top.
Yes. The daily log includes a hydration tracker with a personal goal, plus trigger tags you can attach to any entry — weather, exertion, stress, and more. Over time this builds a picture of what tends to precede a bad day.
Hemo is free to start — logging, 7-day stats, Emergency SOS, community, and the basic care hub don't require payment. Hemo+ unlocks unlimited history, AI insights, and PDF reports for $7.99/mo or $59.99/yr, with a 7-day free trial and a 50% hardship discount for qualifying users.
