Between clinic visits, you’re the one keeping track — of the doses, the pain, the bad nights, and the people who would come for you.
01 · What it does
One app for the everyday and the bad days.
Medicines
Medicine reminders
Add folic acid, hydroxyurea, penicillin or anything you take, with the times. Reminders come from your phone, so they work without internet.
Log
Pain and symptom diary
Score your pain from 0 to 10 and tick symptoms. Logs save offline and sync later, and your history is there to show your care team.
Family
Guardians who see alerts — nothing else
Invite a parent, partner or friend with a code. They get your alerts and what triggered them — not your diary or medicines.
02 · When it’s serious
Help is one hold away.
Hold Get help. Your guardians get an urgent alert that rings — even when their app is closed (their phone needs internet and notifications on). When they reply, you see it.
Automatic
Alerts can also start on their own
A pain score of 8 or more, an emergency symptom such as chest pain, or 3 missed doses in a row sends an alert to your guardians.
Offline
No internet?
Your alert is saved on the phone and goes out first as soon as you’re back online. The app doesn’t send SMS — from Get help you can call or text your phone contacts yourself.
Always
Emergency services, always one tap
“This could be an emergency. Go to the nearest emergency department or call emergency services now.” The call button is right there on the Get help screens.
03 · Ask
Answers from the guidelines, with sources.
Ask about your care in plain words. An AI language model writes the answer using only passages from three clinical guidelines, and shows the source. It can be wrong, so check with your care team.

04 · How it treats you
01
Your diary stays yours
Guardians see your alerts and what triggered them — not your diary or medicines.
02
Made for patchy data
In the phone app, logs and reminders work offline and sync when you reconnect.
03
Easy to read
A typeface designed for low vision, light and dark mode, and your phone’s text size.

05 · Questions
Good to know.
Does it replace my doctor or hospital?
No. SCD Assistant helps you keep track and stay connected between visits. It doesn’t diagnose, and it doesn’t give medicine doses. In an emergency, call emergency services or go to the nearest emergency department.
Which phones does it work on?
Android 7.0 or newer, and iPhone with iOS 15 or newer. The iPhone version is in beta through Apple’s TestFlight.
Do my guardians need the app?
Yes, to get alerts. They sign up as a guardian and join with your invite code (it expires after 24 hours). They see your alerts only. You can also save phone contacts who don’t use the app, and call or text them from Get help.
Can I use it on a computer?
Yes. The web app runs in an up-to-date browser on any phone, tablet or computer, and you can add it to your home screen or desktop. It needs internet to log and for reminders, so for patchy data use the phone app.
Does it work without internet?
In the phone app, reminders and logging work offline. Alerts and Ask need internet: an alert made offline is saved and sent first as soon as you reconnect. The web app shows what it last loaded and still opens Get help, but logging waits until you’re back online.
What happens to my questions in Ask?
The question text is sent to a language-model service to write the answer from the guideline passages. Don’t put your name or other personal details in a question.
Where is my data stored?
On servers in Frankfurt, Germany. You need an account so alerts can reach your guardians.
Who made it?
SCD Assistant started as a final-year computer science project, and this is an early test version. The people in the screenshots are invented demo accounts.
Help us test it.
