Dainvo

Dainvo is a planning workspace for people who want calendars, task services, and project work in one place. It is best suited to desktop users coordinating several providers while keeping project notes and file links on their computer. Its breadth is useful, but the Free plan has firm caps and its mobile apps remain in Early Access.

Overview

Dainvo combines calendar planning, task scheduling, meeting links, and project organization. Connected calendar events and tasks sync with their respective providers, while Project Notes and local file links stay on the user's computer. Its local SQLite store is encrypted, with the key protected by operating-system secure storage. This is a useful balance for people who want provider sync without putting project notes and file references in the same connected services; it is not an entirely local system.

Support is available through problem reporting in app settings and a contact form. Dainvo is owned and operated by Intagri Technologies LLC, registered in Delaware, with Canadian and Irish ownership.

Key features

Calendar views include day, week, month, year, and list, alongside weather and time-zone information. Dainvo connects Google, Outlook, Apple, CalDAV, and local calendars. That range makes it a practical hub for people already using more than one calendar provider, though the benefit depends on those services being part of the user's routine.

Task integrations 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, one level of subprojects, notes, file links, and multiple calendar blocks. This structure can connect task lists to scheduled project time, but the single subproject level may be limiting for work that needs deeper hierarchies.

Meeting links are supported 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 useful safeguard for users who want AI assistance without automatic edits.

Pricing

Dainvo is freemium, with a 7-day Pro trial. Free costs nothing and includes one non-Linux desktop and one active mobile device. After the trial, Windows and macOS users can keep up to four active integrations and 100 active synced Dainvo Tasks; Linux allows unlimited integrations. Those caps make Free a reasonable way to try a focused setup, but users with larger task backlogs or several connected services may outgrow it.

Pro — Launch Price (monthly) costs $5 a month, billed $5 USD per month. Pro — Launch Price (yearly) costs $48 a year, billed $48/year. Both include everything in Free plus Projects and Project blocks, unlimited integrations and active synced Dainvo Tasks, My Day, and a desktop Inbox. The monthly plan suits users who want flexibility; the yearly plan costs less over twelve months at the stated prices, in exchange for an annual commitment. Both are aimed at people whose work exceeds Free's integration or task limits, or who need project planning.

Platforms

Dainvo lists apps for Android, iOS, Linux, macOS, and Windows. Desktop apps are part of its offering, while Android, iPhone, and iPad apps are marked Early Access. That status makes mobile access less compelling for anyone who needs a mature mobile workflow; desktop-first users have the clearer fit.

Who it's for

Dainvo is a strong candidate for people who coordinate calendars and task services across providers, schedule focused work, and want project notes and file links kept on their own computer. It is less suitable for users who need an all-local system, a deep project hierarchy, or dependable mobile apps as the center of their workflow.

Pros and cons

• Pros: Multiple calendar and task integrations bring provider-based planning into one workspace.
• Pros: Project blocks, ordered tasks, deadlines, notes, and file links connect project planning with calendar time.
• Pros: Project Notes and local file links remain on the user's computer, and the local SQLite store is encrypted.
• Cons: Free is capped at four active integrations on Windows and macOS and 100 active synced Dainvo Tasks after the trial.
• Cons: Mobile apps are in Early Access, so users who depend on a polished phone or tablet workflow should look elsewhere.
• Cons: Connected events and tasks still sync with their providers, and Projects support only one level of subprojects.

Verdict

Choose Dainvo if you want provider-connected calendars and tasks alongside scheduled project work, while keeping project notes and file links on your computer. Its combination of integrations and project blocks is the main reason to pick it. Look elsewhere if you need a mature mobile app, a fully local workflow, or more than one level of project subprojects.
