Siilo is a secure messenger for medical professionals. It's the biggest network of doctors, nurses, physiotherapists and other professionals in healthcare.

Securely collaborate with colleagues about patient care and challenging cases, independent of location or direct availability.

Messages are sent using advanced end-to-end encryption and data is stored encrypted on your phone. Additionally, the app is pin code protected. Photos are saved separately from your normal personal photos in a secure, encrypted media vault in the app.

You can invite and connect with all your colleagues and other medical professionals, independent of specialisation or organisation. Group chats are easily created and managed with up to hundreds of users.

Siilo forms the secure, digital connective tissue between medical professionals across the globe for communication, sharing knowledge, and medical crowd sourcing.

What’s New

Version 4.8.0

We've simplified group management! Tap on the group name to learn more about it. When inviting new members to a group, you will be prompted to connect if the prospective member is not a contact or to send a Siilo invite if the prospective member is not a user. Admins now have greater control over who can add new members.

We've also resumed our verification process to ensure users are always connecting to a real person. Unverified users will be prompted to start the process from Profiles.

This is the WhatsApp for Medicine

Phenomenal app! Superior performance! No other secure messenger comes close to this app!

Verification is ridiculous

Even though I have submitted my work email and my state license they still want more personal information to get full access. Seems to be a great app but the verification process seems a little too invasive.

Verification process is ridiculous. Not enough users. Deleted.
