+# InfiniTime Vision
+
+The purpose of this document is to steer efforts towards a common goal, and as such should be taken into consideration with all developments.
+
+## InfiniTime
+
+InfiniTime is a community-built smartwatch firmware.
+It offers freedom and privacy advantages unavailable to users of proprietary wearable technology.
+
+InfiniTime is not to be used for medical or other health tracking purposes.
+
+## Core Principles
+
+- Keep It Simple
+- Reliability
+- Battery efficiency
+- Easy and simple navigation
+- Behaviour should be predictable and easy to understand
+- Prefer solid default experience over customization
+- Personalization is achieved through custom watchfaces.
+  More options may be available through a companion app.
+- Use standard protocols and methods
+
+## Long term vision
+
+The perfect version of InfiniTime would include:
+
+- Capability to sideload apps and watchfaces
+- Only a minimal feature set in the flashed firmware.
+  Users would add the features they want.
+- Ports to other devices
+- Translations
+- Great user documentation
