Sum, Ergo is a unique meditation experience. Most people look to meditation to help them relax, lower stress and anxiety, and have a more restful sleep. Reflection, on the other hand, is meant to help you to discover a resilient, and abiding world view that brings meaning and happiness into focus.

We measure success by whether we can help you:
+ Relax and Reflect
+ Act not React
+ Cultivate Conscious Choice

We value your time, and the reflection sessions are short (around 2 minutes long). We - currently over 150 in total - are carefully curated and organized into six categories that collectively covers most aspects of human experience:

Happiness | Harmony | Desire | Duty | Truth | Self

A tour of Sum, Ergo is available for free upon downloading the app. So start meditating and reflecting now!

The app can optionally integrate with Apple HealthKit to log your Mindful Minutes!

How does it work? The idea is simple. Knowledge about our own lives can only be obtained through discursive reasoning. The reflection sessions are meant to stimulate one’s own process of reasoning about their own lives. Through reasoning, we can build a stable, and abiding world-view.

Though the particulars of each person’s life are vastly different, there are fundamental principles that underlying our existence. This can only be the case if the meaning of happiness, harmony, duty, desire, truth, and self can all be derived from the simple facts of our existence. That is why, the app itself, is named, “Sum, Ergo”, which means “I am, therefore” in Latin. The name itself asks us the question of what is the nature of our existence, and what does it imply.

The app is designed with a deep commitment to our users. It is priced for affordability. And we value user's privacy (see and for more information).
