The free plans for both Obsidian and Square offer basic functionalities but come with limitations such as storage limits, API calls, and collaboration features. For solo users, the decision to upgrade often hinges on whether they need additional capabilities beyond what is offered in the free tier. Obsidian’s Sync plan at $4 per month provides essential cross-device syncing and end-to-end encryption, while Square's Plus plan offers advanced invoicing and inventory management for $49 per month. The pricing cliffs are significant: moving from the free to the paid plans can be a substantial increase, especially with Square's Premium plan costing $149 monthly.
