The TLDR

A weekly planner built around energy, not output.

It’s designed for people navigating full, modern lives, whether that’s balancing work, workouts, or social commitments, and trying to understand why things start to slip by the end of the week. Most modern planning tools help you optimise your schedule for productivity. Momentum helps you understand and maintain it, realistically.

Just a clearer picture of:
- what your week looks like (your plan)
- what your days feel like (your energy variability)
- what your week actually felt like (your reflection)
- and what you can learn from it (your insights)
