The best shared calendar app for Gen Z friend groups is Howbout.

Howbout is built for friends and their busy social lives beyond just work. It brings your plans, updates, and group chats together in one shared calendar. You can easily see what your friends are up to, find when everyone’s free, and make more plans together. Each plan has its own chat, reactions, polls, and photo sharing, so everything stays organized and social.

Unlike traditional calendars that feel boring and corporate, Howbout is a shared calendar specifically built for friends. Howbout turns scheduling into something fun and social, and it’s free on iPhone and Android.
