Journaling App Design with Advanced Features

I'm seeking a talented designer to create an engaging, minimalist design for a journaling app. The app will cater to both basic journaling needs and incorporate advanced features, such as the ability to input video or audio. These inputs will be transcribed and processed into text by the system.

Key project phases:
- MVP: Focus on designing essential features for basic journaling
- V1: Implementing the initial version based on MVP feedback.
- V2: Refining the app design and features for the second version.

The ideal candidate should have a strong portfolio showcasing experience in designing for iOS, Android and Web platforms. Your design should be minimalist, avoiding clutter and focusing on simplicity and ease of use. Please share your expected price and relevant portfolio.
