34. Platform Research
• tawkon & nascent brainstormed possible implications of tawkon running in the
background
• Different behaviors interaction styles were considered
• New platform, new questions:
• How does the app interact with other apps?
• How do notifications look?
• Where are the settings ?
• Widgets ?
• What are the best practices?
• What are the platform guidelines?
Outcome: | Carmel Ventures 14.01.11 34

35. Schematic Design
Schematic designs were refined based on iPhone s to accommodate
background running, notifications, Android guidelines best
practicesSpecial care was given to being good citizen on Android,
as well as using native controls UI elements where possible.
