Dainvo

Dainvo is a planning workspace that brings calendars, tasks, projects, meetings, and notes together. It is best suited to people who coordinate work across several calendar and task services and want project notes kept on their own computer. Its range is substantial, though the free tier is capped and the mobile apps remain in Early Access.

Overview

Dainvo combines connected scheduling with local project material. Calendar events and tasks sync with their respective providers, while Project Notes and local file links remain on the user's computer. Its local SQLite store is encrypted for all users, with the key wrapped by operating-system secure storage. That is a useful distinction for people who want local project notes, but Dainvo is not an all-local alternative to cloud-backed calendars and task services.

Users can report problems from desktop or mobile settings, with a contact form also available through support. Dainvo is operated by Intagri Technologies LLC, registered in Delaware, with Canadian and Irish ownership.

Key features

The calendar has day, week, month, year, and list views, plus weather and time-zone information. It connects Google, Outlook, Apple, CalDAV, and local Dainvo calendars. This makes it a practical hub for people who need to bring several calendar sources into one planning routine, rather than a narrow calendar for a single provider.

Task connections cover Todoist, Microsoft To Do, Google Tasks, TickTick, monday.com, and Obsidian. Users can schedule individual tasks, group them into Buckets, and plan work sessions for Projects. Projects add ordered tasks, deadlines, notes, file links, multiple calendar blocks, and one level of subprojects. That structure suits work that needs both task-level scheduling and a modest project hierarchy; deeper nesting is not part of the described model.

Meeting links can be set up for Google Meet, Zoom, Webex, and Microsoft Teams. Supported desktop packages also include ChatGPT and Claude, and external ChatGPT, Codex, or Claude clients can connect through MCP. Dainvo asks before making changes, a sensible safeguard when an assistant can affect planning data.

Pricing

The Free plan costs nothing and includes a 7-day Pro trial, one non-Linux desktop, one active mobile device, and up to four active integrations on Windows and macOS; Linux allows unlimited integrations. After the trial, Free is limited to 100 active synced Dainvo Tasks. Those limits make it a reasonable way to try the workflow, but a poor fit for someone who needs several devices, more than four integrations on Windows or macOS, or a larger synced task set.

Pro — Launch Price (monthly) costs $5 a month. Pro — Launch Price (yearly) costs $48 a year. Both include everything in Free plus Projects and Project blocks, unlimited integrations and active synced Dainvo Tasks, My Day, and desktop Inbox. The yearly option lowers the stated cost relative to paying monthly for a year, while the monthly plan avoids committing to an annual term. Pro is the clear choice for project planning or for users who would exceed Free's integration or task caps.

Platforms

Dainvo supports Android, iOS, Linux, macOS, and Windows, with desktop apps and mobile apps. The Android, iPhone, and iPad apps are marked Early Access, so users who need a fully mature mobile workflow should weigh that status carefully. Free permits one active mobile device and, outside Linux, one non-Linux desktop.

Who it's for

Dainvo is a strong candidate for people who plan by calendar blocks, pull tasks from multiple services, and want Projects to hold ordered work, notes, and related links. It is less compelling for someone who needs a generous free plan, deep project nesting, or dependable mobile readiness as a central part of the workflow.

Pros and cons

Pros: Broad calendar and task integrations let users coordinate several providers in one planning workspace.

Pros: Project blocks, deadlines, ordered tasks, and one level of subprojects connect project work to calendar planning.

Pros: Project Notes and local file links stay on the user's computer, while the local store is encrypted for all users.

Cons: Free's four-integration and 100-task caps after the trial can constrain regular use on Windows and macOS.

Cons: Mobile apps are in Early Access, which may be a drawback for users who depend on polished phone or tablet access.

Cons: Project hierarchy stops at one level of subprojects, limiting its fit for complex, deeply nested work.

Verdict

Choose Dainvo if you want one workspace for connected calendars and tasks, project time blocks, and notes that stay local. Its integrations and planning structure are the main reasons to choose it; the free caps and Early Access mobile apps are the strongest reasons to look elsewhere.
