A while back I went hunting for a tracker to fix exactly that. Tried a bunch — none of them stuck: - **[ActivityWatch](https://github.com/ActivityWatch/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](https://github.com/wm94i/Work-Review)** — 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](https://toggl.com) / [RescueTime](https://www.rescuetime.com) / 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](https://github.com/Tomotsugu-dev/Hindsight/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**. ## License
