Productivity App Design

I'm looking for a skilled graphic designer to create flat design graphics for my productivity app. The app will primarily focus on task management, calendar integration, and time tracking.

Ideal skills and experience include:
- Proficiency in flat design
- Prior experience in app design, specifically productivity apps
- Understanding of user interface and user experience principles
- Ability to create visually appealing and functional design elements.
We have a prototype online for reference.
