📝 About this app

MediSOS is a medical emergency siren for iPhone & Apple Watch - you never know when you might need it.

If you get into difficulty and need to attract nearby attention in the event of a medical emergency, you can rely on MediSOS to be there to inform first responders about your medical details. Using the iPhone or Apple Watch app, you can start the medical emergency siren which will then allow first responders to view your medical conditions, medication, general details and much more. The siren can even be started from a Widget or Apple Watch Complication for quick access.


MediSOS contains these great features:

MEDICAL SIREN

Activate the MediSOS emergency siren if you find yourself in a medical emergency and need to attract the attention of people nearby so you can get help. The siren can be activated by pressing the big SOS button in the app or via the Widget and Apple Watch Complication. The siren can be stopped whilst viewing the medical ID when first responders get to you.


MEDICAL ID

MediSOS has been designed for your iPhone and Apple Watch so all of your medical details are within easy reach. You’ll be able to view personal details, medical conditions, allergies & reactions, medication and emergency contacts from the alarm screen.


APPLE WATCH

If you find yourself in a situation where your iPhone is not within easy reach, you can use the Apple Watch app to activate the siren on your iPhone.


WIDGETS & CONTROL CENTER

From your Home Screen or Lock Screen, you can use the Widget to activate the medical emergency siren. The siren can also be started from the Control Center when the toggle is added.


LIVE ACTIVITIES

Whilst the siren is active, MediSOS will display some basic details in a Live Activity that links to the full medical ID or that stops the siren from sounding.


EMERGENCY CONTACTS

If you’ve chosen to add emergency contacts to the app, you’ll be able to call them with just a tap from the alarm screen in the app.


CUSTOMIZATION

MediSOS supports the ability to choose from one of four siren sounds, all of which are great at attracting attention when you need it most.


TRANSLATE

Translate medical conditions, medications and allergies/reactions when travelling abroad.


SHORTCUTS

Manage your medical ID with Siri and the Shortcuts app.


STORED SECURELY

All medical ID data is stored securely on your own private iCloud account using the secure Keychain functionality. No data ever leaves your device.


SYNC

MediSOS was designed to work with the MediWidget, MediWear and MediID apps so you’re able to enter your medical ID once and use it everywhere. Syncing is done automatically through the shared Keychain and enables you to pick and choose which medical ID apps you’d like from the MediApps bundle.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
