Dainvo

Dainvo is a planning workspace for people who want calendars, tasks, meetings, and project work together on desktop. It is strongest for users who value provider-linked scheduling while keeping project notes and file links on their own computer. The trade-off is a capped Free plan and mobile apps still in Early Access.

Overview

Dainvo brings calendars, task services, meeting links, and project planning into one workspace. Connected calendar events and tasks sync with their providers; Project Notes and local file links stay on the user's computer. Its local SQLite store is encrypted for all users, with the encryption key protected by operating-system secure storage. This makes Dainvo a sensible fit for users who want local project material without giving up calendar and task integrations, but it is not an all-local system.

Support is available through problem reporting in desktop or mobile 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 span day, week, month, year, and list, with weather and time-zone information. Google, Outlook, Apple, CalDAV, and local Dainvo calendars are supported. That breadth can help people coordinate different sources in one planning routine, while the range of views serves both daily scheduling and longer-range review.

Task integrations include 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, making the product more useful for structured work than a calendar-and-task view alone.

Meeting links work with Google Meet, Zoom, Webex, and Microsoft Teams. Supported desktop packages include built-in ChatGPT and Claude; external ChatGPT, Codex, or Claude clients can connect through MCP. Dainvo asks before making changes, a useful control for anyone wary of letting AI alter plans without approval.

Pricing

Dainvo is freemium, with a 7-day Pro trial. Free costs nothing. After the trial, Windows and macOS users can keep up to four active integrations and 100 active synced Dainvo Tasks; Linux allows unlimited integrations. Free includes one non-Linux desktop and one active mobile device, so the integration and task caps matter most to users who rely on several services or a large synced task load.

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 desktop Inbox. The yearly price is lower than twelve monthly payments at the stated launch price, while monthly billing avoids committing for a year. Pro is the practical choice for users who need Projects or would exceed Free's integration or task limits.

Platforms

Dainvo supports Android, iOS, Linux, macOS, and Windows, with desktop apps and calendar sync. Android, iPhone, and iPad apps are marked Early Access, so users who depend on a mature mobile workflow should weigh that status carefully. Free also limits active mobile devices to one.

Who it's for

Dainvo suits people who plan across several calendars and task providers, want to turn tasks into scheduled work sessions, and need project notes and file links kept locally. It is less compelling for someone seeking uncapped integrations on Windows or macOS without paying, or for a workflow that depends on fully established mobile apps.

Pros and cons

• Pro: Broad calendar and task integrations bring multiple planning sources into one workspace.
• Pro: Projects combine ordered tasks, deadlines, subprojects, notes, file links, and calendar blocks.
• Pro: Project Notes and local file links stay on the computer, and the local SQLite store is encrypted for all users.
• Con: Free is capped at four active integrations on Windows and macOS and 100 active synced Dainvo Tasks after the trial.
• Con: Mobile apps are in Early Access, and Free permits only one active mobile device.

Alternatives

For a broader Time Blocking Apps comparison, consider which platforms, integrations, and planning limits matter most. Routine is another freemium option spanning Android, iOS, Linux, macOS, web, and Windows; its Free plan includes three integrations, three custom databases, and 250 AI credits.

Pomodoist is worth considering if open-source software under the AGPL-3.0-only license is a priority. Open Sunsama offers free personal use, including a hosted app or self-hosting; commercial use and resale require a commercial license.

Ellie Planner has a Free plan with unlimited tasks, Brain Dump, and iPhone, iPad, and web support. FlowSavvy is an alternative for Android, iOS, and web users; its Basic plan includes one scheduling-hours profile, three repeating auto-scheduled tasks, five task lists, and a two-week auto-scheduling range.

Sorted³ is limited to iOS and macOS, with an iOS Free plan and a one-time in-app purchase for iOS PRO. SuperPlanner is another iOS and macOS option, with Pro Monthly at $4.99 a month and Pro Yearly at $29.99 a year. TimeFinder spans Android, iOS, macOS, web, and Windows and has a Free tier alongside a Premium Lifetime option.

Verdict

Choose Dainvo if you want a single planning workspace that links calendars and task services, supports project time blocks, and keeps project notes and local file links on your computer. Its main draw is that combination of integration breadth and local project material. Look elsewhere if uncapped Windows or macOS use must be free, or if Early Access mobile apps are not suitable for your day-to-day planning.
