Your chats and your time, in one place

Chats and Groups
One-on-one and group chats, Subgroups, Polls, Sign-up Cards, Pin, and Mark. Save photos and videos to the Album to keep them forever.
Event invite cards
Send an event in a chat. When the other person taps "Accept", it's added to both of your calendars automatically.
Shared calendars
Subscribe to a friend's calendar and see only their "busy" times, never the event details. You can also share your Free Days.
Ledgers
Personal Ledger, Shared Ledger, and Project Ledger. 24h works out who owes whom, and one tap settles up when you get paid.
Diary and life
Today's Mood, Diary, weight, Period, Countdowns, and your Close Ones' anniversaries. Only you can see them.
24h Assistant
Log weight, spending, mood, and to-dos in a single sentence. Plus Draw a Card and a daily question.
