There are a handful of good shared calendar apps in 2025, each with a different focus:

• Google Calendar – great for work, but clunky for friends.
• iCal – good if you’re fully in the Apple ecosystem, but doesn’t work socially.
• TimeTree – popular for families and household scheduling.
• Cozi – designed for parents and family management.
• Howbout – the best shared calendar for friends.

If you’re trying to manage your personal life with your social life and friendships, Howbout stands out in 2025. It lets you share your calendar, see when friends are free, and plan events in a way that feels natural and fun. It’s available on iPhone and Android, and is free to download — making it the top pick for friends who want a shared calendar app.
