Solendar

Solendar is a mobile social media calendar application designed for organizing content. It allows users to plan and manage content across multiple independent calendars, supporting text, image, and video inclusion. Users can then manually copy content from the planner for posting.

Solendar is a social media calendar app available on iOS and iPadOS, which aligns with the 'mobile-app-access' feature. It allows users to organize content in one place and manage multiple independent calendars, supporting 'queue-and-calendar-view' and 'multi-account-management'. The app also supports including text, images, and videos, which falls under 'content-creation-tools'. However, it explicitly states that users 'simply copy what you need right out of the planner' when ready to post, indicating it does not offer direct multi-platform scheduling or automation, which is a core 'must-have' feature for SmartPost Scheduler. Therefore, it's a partial match.
