About this app

Lumen brings private conversations and shared expenses together. Message friends and family, split bills in your chat, and keep everyday details organized.

STAY CONNECTED
Send personal and group messages, share photos and files, and connect through voice calls. Personal and group messages and ordinary chat attachments are end-to-end encrypted.

SPLIT BILLS TOGETHER
Scan a receipt, review the details, and split costs equally, by item or with custom amounts. Share the bill in your conversation and track who has paid.

TRACK EVERYDAY SPENDING
Record income and expenses with Money Journal using a short description or supported receipt and document uploads. Review entries before saving, organize them by category, and see your spending over time.

KEEP YOUR OWN SPACE
Save useful messages, write notes, and organize photos and files in your encrypted My Space.

ORGANIZE HELP REQUESTS
Create an Ask Help request in a chat and keep its details, updates and supporting proof together.

PROTECT YOUR CONTENT
Use your Lumen PIN, trusted-device controls and conversation privacy settings to protect access to encrypted content.

Receipt scanning and AI-assisted Money Journal features process content you choose to submit through Lumen and its AI service providers. Review results before saving or sharing. Split Bill and Ask Help track records and status; payments take place outside Lumen.
