No account needed for the free tier (3 ops/day). Pro starts at $4/month for unlimited access. FERPA-compliant for educational use.

Session Stacker is the ultimate tool designed for side hustlers who struggle to maintain momentum while juggling full-time jobs and personal projects. It addresses the critical pain point of forgetting where you left off in your work, which often leads to wasted time and diminished productivity. With Session Stacker, you can seamlessly transition into your next work session without the usual ramp-up period. The core value proposition lies in its simplicity: before ending a work session, you define your next task, ensuring you always know what to tackle when you return. Built specifically for those with limited time and energy, Session Stacker eliminates complex task management systems in favor of a straightforward approach: clear next steps. Plus, it works as a Progressive Web App (PWA), meaning you can access it from any device, making it flexible for your busy lifestyle.
