Picture Purr-fect - You can now download images straight from your chats. The app saves them natively, so grabbing a picture just works. Link and Let Link - Tapping an external link now opens it correctly in your browser instead of getting stuck in the app. Sheet Cat-astrophe Averted - The model selection panel no longer stretches to full screen when opened with the keyboard up. It now sizes neatly to its content every time.

Picture Purr-fect - Describe what you want, and Lumo generates the image right in your chat. Whisker-Sharp Memory - Lumo remembers your preferences and context across chats, so you don't repeat yourself. Everything stays encrypted, fully in your control, and never used inside projects. A Fresh Coat of Fur - New composer, animated background, app icon. A full visual refresh. A Clearer Cat-alog - Choosing between Lite and Max is simpler, with a cleaner layout and better-organized options. When Max is busy under high demand, it's clearly marked so you always know what's ready to use. No more claws for Concern - Add a file Lumo can't read and you'll know immediately. A Long Tail - Long chats tidy themselves up automatically, so you can keep the conversation going without losing the thread.
- v1.5.11mo ago
Send Button Pounces on Cue - The send button no longer jumps the gun and clears your message without sending it. It now waits until your prompt is ready, so every tap sends what you typed fur-sure. Microphone Fixed - Tapping the microphone no longer brings things to a screeching halt. Voice input now works without a cat-astrophe. File Whisker-Weight Limit - Attachments come with a new paw-licy: if your files top 10MB, Lumo gives you a heads-up before sending.
- v1.5.01mo ago
Purr-fected Edit Mode - Editing a message now uses the native composer, just like writing a new one. No more juggling two inputs, one clean, familiar place to make your changes!
