Why Hindsight

Have you ever closed the laptop at midnight feeling like you "worked all day" but couldn't say what you actually got done? A while back I went hunting for a tracker to fix exactly that. Tried a bunch — none of them stuck:

• ActivityWatch — open-source, privacy-first, technically ticks all the right boxes. Honest take: the UI just doesn't pull me in. I'd install it, look at it once, never open it again.
• WorkReview-style apps — couldn't find one with both (a) cross-device visibility and (b) an hourly timeline like iPhone's Screen Time. I really wanted that "what was I doing at 3pm" zoomable view for desktop, and nothing had it the way I wanted.
• Toggl / RescueTime / paid SaaS — these feel built for teams and HR-style "billable hours" tracking. The dashboards are dense, the flow is project-tagging-first, and the data lives on someone else's servers. Wrong tool for "personal awareness."

To fix exactly these gaps, I built Hindsight.

Quick Start

Download the installer for your platform from Releases and install it.

Windows

Download hindsight_x.y.z_x64-setup.exe and double-click to install.

⚠️ First launch will trigger "Windows protected your PC" — the installer is not yet signed with an EV code-signing certificate, so SmartScreen will block it. Click "More info" → "Run anyway" to continue.

macOS

Download hindsight_x.y.z_universal.dmg (Apple Silicon + Intel universal binary), double-click to mount, then drag Hindsight into the Applications folder. The app is signed with an Apple Developer certificate and notarized, so it opens normally without any Gatekeeper warning.

All activity data and screenshots are stored locally by default. If you enable Google Drive sync, only activity metadata will be uploaded, screenshots will not be uploaded.
