Supported by science

Explore the data

SparkRx users reported fewer depression symptoms after using the app. That difference, on average, was big enough to be clinically significant. In other words, it was big enough to have a notable impact on daily life. This trial compared it to a control app: an app that should not help someone’s symptoms. About half of the people in the trial used SparkRx. The rest used the control app. SparkRx versus Control did not show a statistically significant difference. SparkRx participants also used the app more than people usually use depression apps.

Limbix also looked at the SparkRx users who answered all of their weekly surveys. For these users, the difference between SparkRx and Control was statistically significant. This means SparkRx improved depression symptoms more than the Control.
