Healthcare task/activity system needs iPhone App Logo and Splashscreen

C'est ce que RoOS recherchait dans leur logo design

We need an iPhone App Logo and Splashscreen for our healthcare activity system. We currently have one design for our previous name (HAS) which can be seen here (also attached to this project)

We use the white background edition.

We want a new logo that is updated to our new name: RoOS
Feel free to make a completely new one, or use elements from the existing.

Doctors and nurses controls their upcoming tasks through this application. Each task is set to a specific color based on triage (Red is serious and must be handled now, orange, less serious, yellow less serious, green and blue...)

Final design should somewhat be related to completing tasks in a healthcare environment. Involving triage colors is a plus but not a requirement Voir plus
