Alarm Friends

A message to future you. Wake up and show up. Alarm Friends is an alarm clock and a reminder app in one, built around one idea: you do things when you know why, and when someone is in it with you. ALARMS WITH A REASON Give an alarm a name, like Gym or Work, and set it for a time and the days you want. Add a reminder for the morning, and it is the first thing you see when you turn the alarm off. Alarms ring through the iPhone alarm system, so they sound even on silent. WAKE UP WITH FRIENDS Put friends on an alarm and you wake up together. You see who is up, who snoozed, and when they got up. A wake window lets each person pick their own time inside it. Nobody is added without saying yes. REMINDERS AT THE RIGHT TIME OR PLACE Write what you need to remember and pick when: a day and a time, when you get home, when you leave home, or when you get to a place you choose on the map. The reminder waits until then. Place reminders work with the app closed. PLANS AND SHARED LISTS What's the plan? Pick swim, gym, coffee or a meeting, the time and who is coming, all on one page. A group can share a to do list: "I've got it" puts your face on a thing so nobody does it twice. YOUR DAY ON ONE SCREEN Today shows your next alarm, the places where reminders are waiting, and what is left of the day. If you turn it on, your iPhone calendar shows up here too. The calendar is only read on your phone. Nothing is changed and nothing is uploaded. MAKE IT YOURS Themes, colours, styles and fonts you change whenever you like. On iPhone and iPad, in 12 languages. PRIVATE BY DEFAULT No ads and no tracking. Your live location stays on your phone; only the places you pick for reminders are saved to your account. Friends see only what you share with them. Sign in with Apple, Google or a code sent to your email.
