FeedbackSelectable audio biofeedback across multiple metrics
App accessTimer mode is free; premium guided content is optional

Flowtime strengths

  • Combines brainwave and heart-related signals in one meditation device.
  • Offers configurable biofeedback targets and detailed post-session biodata.
  • Supports raw-data export and can be used with audio from other meditation apps.

Things to consider

  • The broader set of metrics is useful for data-oriented users but can be more complex than a simpler training score.
  • Its product positioning is strongly meditation-focused, so users primarily seeking eyes-open focus drills may prefer a different workflow.
  • Premium guided lessons are optional, so compare the free Timer workflow with the paid content you actually expect to use.
