About the project

Bivvy is a mobile messenger for everyday conversation, built along the lines people already know from the mainstream apps. You talk one to one, gather group chats with family, friends and people who share an interest, send voice notes and short video circles, swap photos and files, and make audio and video calls. The interface follows a familiar model: anyone who has used a modern messenger will find their way around without being told, and anyone opening this kind of app for the first time will find what they need across three tabs — chats, calls, profile.

What was asked for

  • A full messenger on a par with the apps people already use
  • Private and group chats with every message type
  • Calls and video calls straight from the chat
  • A tidy profile and easy work with groups

Beetrail built Bivvy, an app that holds all of everyday communication: private chats, team discussions, audio and video calls. The messenger supports every common message type, from text and voice notes to short videos and attachments. Visually it runs on a dark background with warm gold accents.

The pain

Talking to people stopped being only typing a long time ago: today a chat carries voice notes, video circles, photos and files. Yet some messengers are missing half of those formats, and others bury them under settings and features nobody asked for. We wanted all of everyday communication in one place, with the full set of modern formats and an interface you can read at a glance.

The fix

Bivvy gathers everyday conversation into one mobile app with a clear interface. In private and group chats you can type, record a voice note or a short video circle, send photos and documents, leave reactions and quote a reply. An audio or video call starts from the same chat, with camera switching, mute and speakerphone. The dark theme with warm gold accents keeps the interface calm and out of the way of the conversation.

What the app does

Bivvy follows a familiar model: three tabs along the bottom — chats, calls and profile. Inside a chat sit all the usual ways to talk, from text and voice notes to photos, files and video calls.

Every chat in one list

A single way into all your conversations. Private and group chats live in one list that reorders itself by recency, so what matters is always on top. Search covers not just names but the text of every message, old threads included. Marks on each row show where a reply is waiting and which chats are muted.

New chat and contacts

One screen with every way to start talking: find someone by phone number, put a group together, send an invite link, or pick a person from your own contact book. Even a long contact list scrolls instantly thanks to the alphabet index down the side.

Three Bivvy conversation screens: voice notes, files and a video circle

One-to-one chat

A conversation between two people where every format carries equal weight: text, a voice note, a video circle or a camera shot all go in one movement, without switching apps. Voice notes arrive with a live waveform you can scrub to the part you need instead of listening again from the start.

Group chat

Every group gets its own card with a cover and a short description that set the tone of the shared space. Everything members have exchanged collects into a section filtered by attachment type, so even an old photo or document turns up straight away. Owner and admin roles keep even a large chat manageable, and invite links make adding people quick.

Call history

Calls sit in their own section rather than getting lost among the messages. Missed ones stand out in red, and the full history is kept without limits. Calling back takes one movement and picks the same kind of call as last time, voice or video.

Video call

A full video call with everyone on screen at once. Your own camera sits in a floating window you can put anywhere so it never covers the conversation. Switching camera, muting audio or video and speakerphone are all one tap away.

User profile

A personal page showing only what matters: name, a short line about yourself and a phone number. Interface language sits on its own switch, so the app is comfortable whatever language you speak.

  1. We looked at how people actually use messengers day to day, and listed the formats you cannot ship without.

  2. We built the design system: three clear tabs, a dark theme with gold accents and as few settings as possible.

  3. We built the core so that every message type runs through one flow.

  4. We added audio and video calls that hold up equally well between two people and in a large group.

  5. We keep Bivvy in real use with real users and keep refining the details on their feedback.

How we built it

Result

Bivvy is a messenger ready for daily use that covers the whole range of everyday conversation: private and group chats, every familiar message type, audio and video calls. The familiar three-tab logic and the dark theme with gold accents make the first encounter comfortable for anyone, whatever their age or experience. The app is in real use and keeps developing on live feedback.
