How to choose
Choose Microsoft Outlook or Apple Calendar if you are locked into the Microsoft 365 or Apple ecosystems respectively, as they lack native apps for rival platforms. Opt for Google Calendar, Todoist, or TickTick if you need cross-platform availability across Windows, Mac, iOS, and Android.
Select Todoist or TickTick if your workflow centers on managing tasks, sub-tasks, and habits rather than time blocks. Choose Google Calendar, Fantastical, or Apple Calendar if your primary need is scheduling events with optional task syncing.
Prioritize Fantastical, Todoist, or TickTick if you want to add events and deadlines using conversational phrases like 'submit report every Friday'. Google Calendar and Apple Calendar do not highlight this feature, while Microsoft Outlook focuses on flagged emails becoming tasks.
Google Calendar and Apple Calendar offer full features for free, making them ideal for budget-conscious users. Microsoft Outlook requires a paid business plan or expensive personal subscription, while Todoist and TickTick offer limited free tiers that upgrade to paid plans for advanced features.
Our verdict
Microsoft Outlook is the top pick for corporate departments, law firms, and teams using Exchange or Microsoft Teams due to its deep integration and unified interface. Google Calendar is the runner-up, best suited for students, freelancers, and anyone wanting a reliable, free calendar that works everywhere.
