About

UnderLine

Features
Read full description

UnderLine is a one-to-one messaging app that lets your conversation partner see your words in real time while you type. Unlike conventional messaging apps, where the other person sees your words only after you tap Send, UnderLine lets the conversation begin from the moment you start typing. When you delete draft text, the change is also reflected on the other person's screen. This makes it possible to share the rhythm of a conversation and the way words take shape, even when you are apart. Key features - Real-time display of text while it is being typed - Simple one-to-one messaging - Add friends using public IDs or QR codes - See in your conversation list when someone is typing - Search your contacts, and your conversation list by name or message - Mute notifications, pin conversations, or hide them from your list - Push notifications for new messages - Blocking, reporting, and in-app account deletion - Encrypted device-to-device transfer using a QR code - Encrypted iCloud backup and restoration Message bodies and live-typing text are end-to-end encrypted. Push notifications never include message content. Important notes - Live typing is visible while the other person has the same conversation open. Because text may be seen before you tap Send, do not type anything you do not want the other person to see. - Enable notifications to receive new-message alerts while the app is in the background or closed. Message content is not shown in notifications.

Aora is your school, full screen. Open it and you see what your campus is actually doing right now. It's not an endless feed from everywhere. It's the people you go to class with, where your friends are, and the plans forming for tonight. NOW Say what you're down for in one tap: food, the gym, studying, a party. Pick a start and end time, add a place, and choose who sees it and who gets a ping. Friends tap I'm down, and anyone who can see it can ask to come. THE MAP Your campus on one map. See friends who share their location with you, every plan and event pinned where it's happening, and the places your friends want to go. Tap a friend to see where they are, how far away, and the weather there, then get directions in Apple Maps. PLANS Start one in a few taps with a place, a day, a time and a cover. Say you're going and your face lands on it. Friends can comment and invite people, and everyone going gets a ping when it starts. PLACES Save the spots you want to try and see which friends want to go too. Mark the ones you've been, rate them, and add a photo. Any saved place turns into a plan in one tap. POSTS AND BURST Post a photo or video in one shutter. Hold the shutter to shoot a Burst, then swipe through and keep your favorites in Memories. Add any of them to your profile whenever you like. NIGHTS THAT ACTUALLY HAPPEN Host an event in under a minute. Send one link and people RSVP by name, whether or not they have Aora. See which friends are going, run the door from your phone, keep a waitlist, and share one album with everyone who was there. SHARE YOUR LOCATION, YOUR WAY Choose exactly who sees you and for how long. Friends you share with see where you are, your battery, and whether you're on your way. Stop any time. BUMP TO FOLLOW Hold two phones back to back to follow each other instantly. YOUR HOUSE, IN ONE PLACE If you're in a house, it gets its own page with announcements, a calendar, an album, points, dues, contacts and a roster, one tap from Home. MESSAGES Reply to anything and it opens a thread. Send a voice note, or ask a friend for a pic of what they're up to. CRUSHES Pick people quietly. Nobody is told unless it goes both ways. --- Aora is campus only. You join with a school email or an invite from someone already in, and you only ever see your own school. Every post can be reported and every account can be blocked, both ways, instantly. We have zero tolerance for objectionable content and abusive users.
