How Mindwtr compares
Mindwtr is a free, open-source GTD task manager for Linux, macOS, Windows, iOS, and Android. It works offline, never asks for an account, keeps your tasks on your own devices, and syncs only where you tell it to. Here is how that stacks up against seven well-known alternatives — sourced, dated, and kept honest, including the rows where they win.
Mindwtr next to seven other task managers
A respectful comparison based on each product’s current public capabilities: Todoist, TickTick, Everdo, Nirvana, OmniFocus, Things 3, and Microsoft To Do. The home page carries a compact four-app version for a quick look; this page is the full matrix, and it is the one to trust when the two differ.

Method. Checked against each maker’s own product, pricing, download, and help pages. “Full GTD” requires first-class Inbox, Next, Waiting, Someday, Review, and sequential projects. “Sync encrypted before it leaves your device” means the app encrypts your data locally, with a key or passphrase the vendor does not hold; transport encryption and server-side encryption at rest are table stakes and are not counted here. “Built-in import” means an importer for another task manager’s data, not a hand-built file format. “No” means official sources do not document the capability; “Partial” means part of it is documented — the notes below say which part.
What each one costs. Mindwtr is free under the AGPL-3.0 license, with no paid tier and nothing to unlock. Microsoft To Do is free too — Microsoft’s own page says “use Microsoft To Do for free” — and asks for a Microsoft account rather than payment. Todoist, TickTick, and Nirvana each pair a capped free plan with a paid subscription: Todoist’s free Beginner plan stops at 5 active personal projects, with Pro at $7 per month or $60 per year and Business at $10 per user per month; TickTick Premium is US$49.99 per year; and Nirvana prices its Pro plan on the page linked above. Everdo’s free tier is capped at five projects and two areas; Pro removes both caps for a one-time $99.99, and syncing over the internet through its Encrypted Sync Service adds a subscription ($1.66/month on that page). OmniFocus 4 is $74.99 (Standard) or $149.99 (Pro) as a one-time license, or $99.99 per year by subscription, with web access bundled into the subscription or sold separately at $4.99/month or $49.99/year. Things 3 is a one-time purchase per platform — Mac, iPad, iPhone, and Vision are bought separately, the Watch app comes with the iPhone one — and Cultured Code sets prices in US dollars and sends you to the App Store for your country’s figure.
Cell notes. Todoist and Everdo are “Partial” on import because Todoist documents CSV import and export per project rather than importers for named apps, and Everdo documents a JSON import format you assemble yourself plus an export. TickTick imports from Todoist, Microsoft To Do, Wunderlist, OmniFocus and others and generates a backup file you can take away; Things imports from Apple Reminders, Todoist, and OmniFocus but documents no CSV or JSON export — only a copy of its SQLite database or a printed PDF. Nirvana exports .csv, .xml, or .json from the account dashboard and documents a guided Weekly Review in its AI assistant; it ships Mac, Windows, iPhone, iPad and Android apps, but no Linux one. OmniFocus and Things are “Partial” on platforms because both are Apple-only: Omni lists Mac, iPhone, iPad, Watch and Vision Pro and points PC and Android users at OmniFocus for the Web, and Cultured Code sells Things for Mac, iPad, iPhone, and Vision only. Both are “Partial” on accounts because the apps open without one, but a second device does not: Cultured Code writes that “a free Things Cloud account is required”, and that article also rules out choosing your own destination: “Third-party services like iCloud, Dropbox, etc. are not supported.” OmniFocus is “Partial” rather than “Yes” on sync destination because it syncs to your own WebDAV server — the same page documents its encryption and its CSV, plain-text and HTML exports — but its web app can’t read a database you host. For wearables, Mindwtr supports a native Apple Watch companion and direct Pebble Index 01 smart-ring capture. Todoist lists Apple Watch and Wear OS apps, and TickTick lists Apple Watch support. Everdo’s published downloads and Nirvana’s published apps do not list a wearable app. OmniFocus and Things both document native Apple Watch apps. Microsoft To Do is “Partial” because its official Watch instructions surface tasks through Apple Reminders instead of a native Microsoft To Do Watch app. Microsoft To Do is “Partial” on offline: Microsoft documents that “you’ll still be able to use To Do in offline mode” while warning that unsynced data is lost if you sign out, and your tasks live on Exchange Online servers. It wins the collaboration row, where it assigns tasks in shared lists, alongside Todoist and TickTick; Mindwtr’s People and Waiting views record delegation inside one person’s GTD system; they do not invite another user or assign a task to a member account. That is why the multi-user collaboration row is a “No” in our own column. Remaining sources: Mindwtr, Todoist apps and offline mode, TickTick apps, Everdo projects and Encrypted Sync Service, the OmniFocus glossary and feature list, Things features, and Microsoft To Do system requirements.
Looking for a GTD app that doesn’t require an account?
Mindwtr never asks you to sign up, log in, or verify an email. You install it, and your tasks live in a local database on your device — plain SQLite plus a documented JSON format you can export at any time. There is no server-side copy of your data unless you set up a sync target yourself, and no analytics account shadowing your usage. Most mainstream task managers (Todoist, TickTick, Nirvana, Microsoft To Do) require an account because your data lives on their servers. Mindwtr asks for none because your data never leaves your device unless you send it somewhere. OmniFocus and Things sit in between: the apps open without signing in, but the moment you want a second device, you need the vendor’s sync account.
An open-source Todoist alternative
If you like Todoist’s capture-anywhere workflow but want open source and data you own, Mindwtr covers the same ground — quick capture with natural-language dates, projects and labels (contexts), recurring tasks, reminders, widgets, and calendar views — and adds the full GTD method: a real Inbox-processing flow, Next/Waiting/Someday lists, Areas, sequential projects, and a guided Weekly Review. The honest trade-off: Mindwtr is built for one person. It has no shared workspaces, task assignment, or team comments, and its integration ecosystem is smaller: automation runs through a local API, CLI, and MCP instead of a hosted integration marketplace. Migration is one import: Mindwtr reads Todoist exports directly.
Local-first, without giving up your other devices
Some privacy-focused task managers keep data on one device and stop there. Mindwtr is local-first and multi-device: pick a sync route you already trust — iCloud, Dropbox, WebDAV, a folder watched by Syncthing, or a small server you host yourself — and every device merges changes locally with a documented conflict-resolution algorithm. File-based sync targets (folder, WebDAV, Dropbox) can additionally be protected with an optional passphrase, so the files your sync provider stores are encrypted before they leave the device. Sync is opt-in; turn it off and Mindwtr stays entirely on your device.
What Mindwtr doesn’t try to be
A fair comparison includes what we don’t do. Mindwtr is not team or project-management software — no shared boards, assignees, or discussion threads. It is not a calendar app (it integrates with the calendars you already use) and not a note-taking app (notes attach to tasks and projects; long-form writing belongs in your editor, and an Obsidian integration bridges the two). If you need shared workspaces, a team tool will serve you better; if you want one trustworthy system for your own commitments, the narrow scope is what makes it work.
Head-to-head comparisons
If you are weighing Mindwtr against one app in particular, these pages go deeper — a one-on-one table, the honest trade-offs, and the migration path from each: an open-source Todoist alternative, a TickTick alternative, OmniFocus for Linux, and a free GTD app for Android. If you are surveying the field rather than weighing one app, there are honest roundups of Todoist alternatives, TickTick alternatives, and the best free task managers — each profiles the competition fairly, our own catch section included.
Common questions
Is Mindwtr really free?
Yes. Mindwtr is free software under the AGPL-3.0 license — no subscription, no premium tier, no in-app purchases, no feature paywall. Development is funded by donations.
Where is my data stored?
On your device, in a local SQLite database, with JSON export and backup you control. See data & sync for the on-disk format and backup guidance.
Does Mindwtr work offline?
Entirely. Offline is the default state, not a degraded mode — sync, when configured, catches up whenever a connection is available.
Can I move in from another task manager?
Mindwtr imports from Todoist, TickTick, OmniFocus, DGT GTD, and CSV, keeping projects, dates, and recurrence where the source format records them. See the import guides.
Can I leave?
Any time. Your data is already on your disk in a documented format, and CSV/JSON export is built in. No export fee, no account to close, nothing to cancel.
