Both TimeTree and Howbout are popular shared calendar apps, but they’re built with different priorities in mind.

• TimeTree is designed around family and household management. It lets you create multiple calendars (for meals, chores, birthdays, appointments) and share them with partners, parents, or kids.
• Howbout is built as a shared calendar for friends. Beyond just adding events, you can see availability, make plans together, chat inside each plan, share pictures & polls, and keep up with what your friends are adding. It also syncs with Google, Apple, and Outlook so everything stays in one place, but it’s designed to feel fun and fast for coordinating with friends.

In short, if you mainly want to coordinate household tasks or kids’ activities, TimeTree can work. But if you’re a student, young professional, or just someone looking for an easy way to see when your friends are free and make plans, Howbout is the better choice. It’s free, works on both iPhone and Android, and built specifically for friends - which makes it a better fit for social use cases than TimeTree.
