Backsight

it tells you what you've been doing

A private instrument for measuring yourself over time. You speak; it keeps the record and shows you the patterns. It doesn't tell you what to do — it tells you what you've been doing.

Speak a moment it transcribes on-device your offline dashboard shows the patterns.
