Velprium

Velprium is a time workspace that connects to Google Calendar and turns it into something closer to a bullet journal. The core idea is tracking not just what you planned to do but what actually happened, then reviewing patterns over time without copying data into spreadsheets or separate tools. It stays read-only on your calendar, so it adds context and metadata on top of your events rather than editing them.

The way it works is straightforward. You connect your Google Calendar and Velprium pulls in your events. From there you can add properties to each event, things like status, tags, ratings, notes, and categories, that your calendar does not natively support. None of this touches the original event in Google Calendar. It lives in Velprium's layer, which means you can enrich your schedule without worrying about sync conflicts or losing data if you stop using the tool.

Velprium has four main views. There is a week view that splits time into area columns so you can see how hours distribute across work, personal, health, or whatever buckets you define. There is a diary view for a chronological log. There are weekly and monthly reviews that aggregate your ratings and time by area, comparing the current period to previous ones. And there is an AI assistant called Ask that can help with scheduling questions based on your history.

The target user is anyone who wants more reflection on how they spend time than a calendar alone provides. Freelancers tracking client hours, knowledge workers trying to balance deep work and meetings, students juggling courses and side projects. The templates on the site include a bullet journal setup, a client work tracker, a standard workday log, and a life log for people who want to capture everything.

What sets it apart from other calendar add-ons is the plan versus actual split. Most calendar tools assume your events happened as scheduled. Velprium lets you record what actually went down alongside the plan, so you can see drift over weeks and months. It also aggregates this into weekly summaries without you having to tally anything manually, which is where the reflection actually becomes useful instead of another chore.

Access is free to start. The site describes core features, including calendar sync, all four views, and event properties, as permanently free with no payment information required to begin. Apple Calendar support is listed on the roadmap but not yet available. Velprium stores data locally first and complies with Google's API limited use requirements, so your calendar data stays under your control rather than being shipped off to train models or sold to advertisers.
