Spark Mail

Spark is an intelligent email client that helps you reclaim your inbox by automatically prioritizing important messages. Instead of wading through newsletters and notifications, you see emails from real people first. You can manage multiple accounts from different providers in one unified space, using a Smart Inbox that categorizes incoming mail so you can focus on what matters most.

You can collaborate with your team by drafting emails together in real-time or discussing specific threads in private side-chats. The platform includes a built-in AI assistant to help you draft, rephrase, and proofread replies instantly. Whether you are an individual looking for a cleaner inbox or a team needing better coordination, Spark provides the tools to handle high email volumes without the usual stress.

Structured

Structured is a visual day planner designed to help you take control of your schedule by merging your tasks and calendar events into one clear timeline. Instead of jumping between different apps, you can see your entire day at a glance, allowing you to focus on what needs to be done next without feeling overwhelmed by a long, disorganized list.

You can easily create tasks, set recurring routines, and use color-coding to categorize different parts of your life. The app is built for anyone who struggles with traditional to-do lists, including those with ADHD or anyone who simply prefers a more visual approach to time management. It helps you find structure in your daily chaos by breaking down large goals into manageable, time-blocked segments.
