Velprium

Velprium is a calendar journal that layers structured data and review capabilities onto Google Calendar, transforming scheduled events into queryable time records that reveal patterns in how time actually gets spent. It addresses a gap that calendar applications typically ignore: while they excel at scheduling future activities and sending reminders, they offer almost nothing for understanding past time usage or identifying trends in how days and weeks unfold. Velprium treats calendar entries as data points that can be enriched with notes, moods, ratings, projects, and custom properties, then filtered and analyzed to answer questions like where time goes, which activities feel worthwhile, and what patterns emerge over weeks or months of tracking.

The core functionality lets users attach metadata to any calendar event without modifying the original Google Calendar entry. Someone might tag a meeting with a project name, rate how productive it felt on a five-point scale, add a status like completed or cancelled or rescheduled, note their mood before and after, or write a quick reflection about what happened. These properties exist in Velprium's separate data layer, keeping the Google Calendar itself clean and unchanged while enabling much richer tracking and analysis. The system then allows filtering events by any of these dimensions, so users can pull up everything related to a specific client project, see all meetings rated two stars or lower from the past quarter, review cancelled commitments to understand scheduling patterns, or track cumulative time spent on different categories over any date range.

Four distinct views present this information in different ways depending on what users need at any given moment. The Diary view shows a chronological log of events, functioning like a traditional journal but populated automatically from calendar data with minimal manual input required. The Week view splits time by areas or categories, useful for seeing at a glance how hours distributed across work, personal projects, client obligations, health, or any other domains a user cares to track. The Review view provides daily, weekly, and project-level analytics, surfacing trends and patterns that would be invisible when looking at individual days in isolation. An Ask view introduces an AI agent that can help with scheduling decisions based on the accumulated data and observed patterns.

An optional Plan versus Actual feature lets users compare what they intended to do with what they actually did. This appeals to anyone who schedules tasks optimistically then wonders at the end of the week why nothing went according to plan. By tracking deviations systematically over time, users can identify whether certain activities consistently run over their allocated time, which commitments tend to get cancelled or rescheduled repeatedly, where their planning assumptions fail most often, and what realistic time estimates should look like based on historical data. The feature transforms vague feelings about time management into concrete patterns that can inform better planning decisions.

The platform provides templates for common use cases: bullet journaling for daily reflection and task tracking, client work management for freelancers and consultants who need to log billable time, workday organization for employees who want to understand their productivity patterns, and comprehensive life logging for users tracking everything from meals to workouts to social activities. These templates configure default properties, views, and categories to match specific workflows, reducing setup friction for users who know what kind of tracking they want but would rather not build the structure from scratch. Templates also serve as examples of what structured calendar journaling can look like, helping new users understand the possibilities.

Target users include consultants and freelancers tracking billable time across multiple clients, knowledge workers trying to understand where their days disappear, managers reviewing how they spend time on different responsibilities, and anyone who uses Google Calendar as their primary scheduling tool but feels like they lack meaningful visibility into their actual time usage. The product is particularly relevant for people who have tried dedicated time-tracking apps but found them too demanding to maintain, since Velprium builds on data that already exists in the calendar rather than requiring separate logging for every activity.

Velprium connects through Google OAuth and runs as a web application built with Next.js. It stores all Velprium-specific data separately from Google Calendar and doesn't modify original calendar events, so users can disconnect at any time without affecting their calendar. The platform explicitly states that data is never used for AI training, addressing a common concern about cloud services that process personal information. The service is free to start with no payment information required, and core features including calendar sync, all four views, and full property management remain available without charge.
