Study with your friends, not a room full of strangers

Firefly is a study app for you and the friends you add. You see when they are studying, keep your streaks side by side, and study together in rooms where your breaks line up.

Free. Every account is approved by a person, and you will get an email once your request has been looked at, usually within a day or two.

Company, not an audience

Most places to study online are public rooms. You join, a grid of people you have never met is already there, and the number of them is the selling point.

Firefly works the other way round. There are no public rooms, no matching with study buddies, and no cameras or microphones. The people you study with are friends you added and accepted, or friends of theirs in a group chat you share. That is the whole list.

What is body doubling, and can you do it online?

Body doubling means doing a task while someone else is there doing theirs, in the same room or on a screen, because their company makes it easier to start and to keep going. Yes, it works online, and it does not need video.

A Firefly study room is body doubling with people you know. You see your friends' timers running beside yours, and the quiet fact that they are still at it is most of the point. Firefly does not claim it will fix your focus. It just gives you the company.

Adding friends

Search for a friend's username, send a request, and nothing is shared until they accept. You can cancel a request you sent or decline one you received.

If they are not on Firefly yet, send them an invite on WhatsApp or copy it into any chat. Every account is still approved by a person, so an invite is a way in, not a shortcut.

What your friends can see

Friends see:

Friends do not see your courses, notes, study material, planner or to-do list. Nobody does. The privacy page sets out exactly who sees what.

Can strangers join a Firefly study room?

No. A study room belongs to one of your group chats, and only people in that group can open it. A group chat can only be made with friends, and only the person who runs it can add anyone, and only from their own friends.

So the only people you might meet there who are not your own friends are friends of whoever runs the group. They see your username, picture, messages in that group, and in its study room whether you are focusing or on a break and which course. They do not see your study time, streak or goals.

How a study room works

Open the Focus screen, pick a group chat, and you are in its room. Everyone there sees each other's timers live, with the course each person is on.

Streaks side by side

The Friends page keeps a small board of you and your friends, ranked by current streak or by hours studied this week. It shows the top ten.

The chat list has a feed called Study group, where the updates from you and your friends land. Nobody can type in it. You can only react, with a quick emoji or any other.

Firefly's chat: a list of conversations, including the Study group feed and a group chat, beside an open private chat with a friend

Chat, private and in groups

You can message any friend privately, and make group chats with friends, with a name and an emoji or picture. React to any message with any emoji, and delete your own messages when you need to. Leave a group whenever you like.

If you need to block someone

Blocking someone ends any friendship or request between you. They can no longer find you in search, add you or message you, and they cannot see your profile, study time or streak. In a group chat you are both in, you stop seeing each other's messages, and they no longer see you in a study room you share. You can unblock them later from the Friends page.

Friends are one part of the same app that keeps an honest study timer, a weekly planner, and your courses together. See everything Firefly does.

Questions people ask

Is it better to study alone or with friends?

It depends on the friends. Studying with people who want to talk does not help, which is why a Firefly study room keeps its chat closed until the break.

Do I need a camera or a microphone?

No. A study room shows timers and courses, not faces. There is no video or voice in it at all.

Can people who are not my friends see my study time?

No. Your study time, streak and goals reach friends you have accepted and nobody else. Someone in a group chat with you who is not your friend sees only your username, picture and messages there and, in its study room, whether you are focusing or on a break.

Can my friends see my notes?

No. Friends see your study time, streak, weekly goals if you share them, and short updates when you finish a session. Your courses, notes, files and planner are yours alone.

Is it free?

Yes. Firefly is free while invitations are limited. It runs in a phone or laptop browser, with nothing to install.

Bring the people you already study with

Ask for an invite, add two or three friends, and open a study room the next time you all sit down to work.
