Task management apps for freelancers: what survived 90 days of real client work

Most freelancers should start with Todoist. It balances speed, flexibility, and cross-device sync better than any competitor I tested, at roughly $5 per month paid annually.

The worst Thursday of my freelance career happened in March. I had a pitch deck due for a Berlin startup, three blog drafts for a SaaS client, and a quarterly tax spreadsheet that my accountant needed by Friday morning. I was using Apple Notes for my to-do list because it was already open and it felt simple. By 11 a.m. that Thursday, my list had turned into a scroll of panic. I couldn’t tell which tasks were billable, which were administrative, and which were actually due that day versus next week. I missed the tax deadline by four hours. My accountant charged me a late fee that could have bought a year of any task app on the market.

The spreadsheet itself was the ugliest thing I made that quarter. It had merged cells, colored rows, and a formula that broke when I added a new client line. My accountant emailed back with a single line: “Please send a clean CSV next time.” I was embarrassed. The late fee was €90. The real cost was admitting to a professional that I still organized my life like a student.

It was raining in Barcelona that afternoon. I sat in a coworking space near the marina, listening to office chairs squeak and watching someone microwave fish. I opened every task app I could find and decided to test each one for thirty days or until it broke.

I tried Todoist, TickTick, Any.do, Microsoft To Do, and OmniFocus. Some I loved for two weeks and then abandoned. Some I hated within an hour. Two survived the full 90 days.

What freelancers actually need in a task app

Freelancers have a specific problem. We don’t manage one project. We manage six to ten projects at once, each with a different client, a different deadline culture, and a different communication style. The tool that wins is not the one with the most features. It is the one that respects your time and gets out of the way when you are trying to work.

Here is what I actually need from a task app during a normal week:

• A way to assign tasks to clients so I can filter by “Berlin startup” or “SaaS blog” and see only that work.
• Recurring tasks for weekly administrative stuff like invoicing and outreach, with the ability to skip a week without breaking the recurrence.
• Natural language input so I can type “Draft landing page tomorrow at 9am” and the app understands both the task and the deadline.
• Offline sync because I work from trains, cafes, and airports where WiFi is theoretical.
• A quick-capture method that takes less than five seconds from idea to inbox, because ideas happen in elevators.

Anything beyond that is decoration. I don’t need Gantt charts. I don’t need a dashboard. I need a list that I trust.

Todoist

I have used Todoist for eight months now. I started with the free plan, upgraded to Pro after two weeks, and I pay roughly $5 per month when billed annually. The total cost is about the same as two coffees in London. I would happily pay double.

The first thing that won me over was speed. I can open the app, type “Redesign client invoice Friday #work”, hit enter, and the task is logged under my Work project with a Friday deadline. That takes about four seconds. TickTick is close, but Todoist’s natural language parsing feels slightly smarter. It understands “every other Tuesday” and “the first Monday of the month.” TickTick stumbled on “every other Tuesday” and set it to weekly instead.

Labels are the feature that keeps Todoist in my dock. I tag every task with a client name and a work type. So a task might have three labels: @SaaSClient, @Writing, and @Billable. When Friday afternoon arrives and I need to know how many billable hours I have left, I filter by @Billable and see everything in one list. That one feature replaced a spreadsheet I used to maintain manually.

The recurring task engine is rock solid. I have a task called “Send invoices” that repeats every Friday at 4 p.m. If I am traveling and miss it, the task shows up the next day as overdue. I never lose track of it. Some apps delete the recurrence if you skip a day. That is a dealbreaker for administrative work that doesn’t really expire.

The cross-platform sync is instant. I added a task on my phone while waiting for a train in Amsterdam, opened my laptop five minutes later in a cafe, and the task was already there. I have had sync failures in other apps. Sync is the one feature I refuse to compromise on, and Todoist has been flawless.

Here is what I don’t like. The calendar integration is weak. Todoist has a calendar view, but it is slow to load and doesn’t look great. I usually export my tasks to Google Calendar using a third-party integration instead. The project comments feature is useless for solo freelancers. It seems built for teams. I ignore it. And the mobile widget on iOS is oddly limited. I can’t check off a subtask from the widget without opening the app. That feels like an easy fix that they haven’t bothered with.

I have a small gripe about the Karma system. Todoist rewards you with points for completing tasks, streaks, and leveling up. It sounds fun until you find yourself adding fake tasks just to check them off and keep a streak alive. I caught myself doing this on a Sunday afternoon. The moment I realized I was gamifying an administrative chore, I turned the feature off. It is optional, but the default settings push it hard enough that I imagine some users get hooked.

Despite those flaws, Todoist is the one I kept.

TickTick

I almost switched to TickTick after my first month. It costs roughly $3 per month for the premium plan, which is cheaper than Todoist and includes a few features Todoist charges extra for. The built-in calendar view is genuinely excellent. You see your tasks plotted on a real calendar, color-coded by project or tag, which makes deadline clash obvious. During my March nightmare, a calendar view would have shown me that three deadlines landed on the same Thursday before it became a crisis.

TickTick also has a Pomodoro timer built into the app. I didn’t think I would use it, but I do. I start a 25-minute session on a task called “Write intro draft,” and the app tracks how many Pomodoros I spend on each project. At the end of the week, I can see that the Berlin startup ate twelve Pomodoros while the blog client only took four. That data is useful for adjusting my rates and my time estimates. Todoist doesn’t have this without a third-party integration.

The habit tracker is another bonus. I track “Morning pages” and “Email catch-up” as daily habits, and TickTick keeps a streak count. I know this sounds like productivity theater, but seeing a 30-day streak is weirdly motivating. I don’t open a separate habit app anymore.

So why did I stay with Todoist instead of switching? Two reasons. The first is natural language parsing. TickTick handles simple inputs like " tomorrow at 9am" fine, but it fails on complex recurrences. I tried to set a task to “every third Friday” and it turned into “every Friday.” I caught it, but I shouldn’t have to proofread my task dates.

The second reason is reliability. TickTick synced fine 95 percent of the time, but I had two incidents where a task I added on my phone didn’t appear on my laptop for over an hour. One of those tasks was a client deadline reminder. The delay made me anxious enough that I stopped trusting TickTick for time-sensitive work. If that sync issue was a one-off, TickTick would be my winner. The calendar and Pomodoro features are better than Todoist’s equivalents. But trust is hard to rebuild.

Microsoft To Do

I included Microsoft To Do because it is free, it comes with every Windows installation, and some freelancers swear by it. I used it for ten days and then uninstalled it.

The interface is clean. That is the best thing I can say about it. The My Day feature, which resets every morning and lets you pick which tasks to focus on, is genuinely smart for people who feel overwhelmed by long lists.

The problem is that Microsoft To Do is built for employees, not freelancers. It doesn’t have labels or tags in any meaningful way. It doesn’t have custom filters. It doesn’t understand natural language recurrences beyond the absolute basics. You can’t assign a task a duration or a priority level beyond the star.

For a corporate worker managing a handful of team tasks inside Microsoft 365, it is fine. For a freelancer managing six clients with overlapping deadlines, it is too simple. I felt like I was organizing my work in a shoebox.

OmniFocus

OmniFocus is the most powerful task manager I tested. It is also the most expensive, at roughly $50 for the Mac app and another $50 for the iOS app, with no subscription. That is a $100 upfront cost. For a task app.

I loved the custom perspectives. You can build a view that shows only high-priority billable tasks due in the next three days for a specific client. That level of filtering is unmatched. If you are a Mac-only freelancer with complex project hierarchies and you love tinkering, OmniFocus is the best tool on the market.

I am not that freelancer. I work on a Mac, an iPhone, and occasionally a Windows PC at a coworking space. OmniFocus has no Windows or Android app. The learning curve is steep. I spent two hours setting up perspectives before I added a single task. And the interface looks like it was designed in 2015. It hasn’t aged well.

I mention OmniFocus because it is the non-affiliate alternative that serious Mac users should consider. Just know that it is built for a narrow audience. If you don’t love fiddling with metadata and contexts, you’ll feel frustrated.

Who should keep using Apple Notes

If you freelance as a side hustle with one client and your task list fits on a sticky note, you do not need any of these apps. Apple Notes is fast, free, and already on your phone. Adding a dedicated task manager will feel like bureaucracy. I know a graphic designer who has used Notes for six years and bills $150 per hour. The tool isn’t holding her back. Her workflow is just simpler than mine.

You should also skip these apps if you do all your work inside a single project management platform. Some freelancers never leave Basecamp or Asana because their clients require it. If your tasks live inside a client-mandated system, adding a personal task manager just creates duplication.

When your task list outgrows a task app

A task app is not a project management system. When you start managing subcontractors, client approvals, and file versioning, you need a tool built for projects, not lists. I wrote about my picks in the guide to the best project management software for freelancers. If your work is visual, you might also need the best graphic design tools for freelancers to keep assets organized alongside tasks.

For time-sensitive client work, pairing a task app with a scheduling tool prevents double-booking. I covered the ones I trust in the review of the best scheduling software for freelancers. And when tax season arrives, your task list should probably remind you to export data from your best accounting software for self-employed.

Questions freelancers ask about task apps

Do I need a dedicated task app or can I use Apple Notes?

If you open fewer than ten active tasks and you serve one client, Apple Notes or a paper list is fine. The moment you balance several clients, recurring deadlines, and project dependencies, a dedicated task app saves hours of mental overhead each week.

Which task app works best for juggling multiple clients?

Todoist and TickTick each handle multiple client projects well. Todoist has cleaner labels and filters. TickTick adds a built-in calendar view that shows deadlines across clients at a glance.

Is Todoist worth paying for?

The free plan covers simple lists. The paid plan at roughly $5 per month gives you reminders, labels, filters, and duration tracking. For freelancers with more than two active clients, it pays for itself in missed-deadline prevention.

Can I share task lists directly with clients?

Yes. Todoist and TickTick both support shared projects. Todoist makes it easier to share a read-only view, while TickTick allows full collaboration if the client also uses the app.

A note on integrations

One question that comes up often is whether these apps integrate with Zapier, Slack, or billing tools. Todoist has native Zapier support and official integrations with Toggl, GitHub, and Slack. I use the Toggl integration to turn a task into a time entry with one click. TickTick also supports Zapier, though the triggers are fewer and occasionally delayed by ten minutes, which makes real-time automation less reliable.

Microsoft To Do integrates with Outlook and Microsoft 365 tasks, but its third-party ecosystem is almost nonexistent. OmniFocus has no official Zapier integration at all. If you rely on automated workflows to connect your tools, Todoist is the clear winner.

This distinction matters less if you treat your task app as a standalone tool. I know freelancers who manually copy task names into Toggl and prefer the ritual of doing it by hand. If that is you, the integration gap doesn’t matter. If you want speed, Todoist’s integrations are the best I tested.

Picking the right tool for your work style

My honest recommendation

Start with Todoist. Set up one project per client, add two labels per task (client and work type), and turn on the Friday invoice reminder. That setup takes ten minutes and saves you from the Thursday-from-hell scenario that cost me my accountant’s patience and a late fee.

If the built-in calendar view and Pomodoro timer matter more to you than natural language speed, switch to TickTick. Both are good enough that the wrong choice is still better than no choice at all. The real mistake is trying to manage six clients in your head because you think task apps are overkill.

Pick one today. Move five tasks into it tonight. You’ll know by Monday whether it fits your work.
