* Smarter AI - Fed our models premium kibble. Now 23% more intelligent and only occasionally ignores you on purpose.
* Better Speech - Fixed bug where everything sounded like hairballs. Speech recognition now understands human (most of the time).
* More Languages - Can now ignore you in more languages! Also fixed that thing where "Hello" kept translating to "Feed me."

Lumo AI by Proton version 2.0.4
Updated At: 2026-09-04
Changes: Version History Photo Paste Pounces In. Paste photos straight into your message on iPhone. Copy an image anywhere, then long-press the composer to open the native edit menu and drop it in.
No Cat Naps Mid-Answer. The screen stays awake while Lumo writes, so you can read along without tapping to keep it alive.
iPad Sidebar Clawed Back. In windowed mode on iPadOS 26, the system window controls no longer cover Lumo's sidebar button, so it's easy to reach again.
Security Fur-tified. Behind the scenes hardening to keep your data where it belongs. Nothing for you to do. 2.0.4 Aug 21 iPad Attachment Menu Un-fur-led - Tapping the plus button in the composer on iPad now opens the attachment menu instead of nothing at all. Adding files from your iPad works again. 2.0.3 Aug 12 Cat Out of the Bag. Pick a custom Lumo with its own personality straight from the composer, and your active choice shows as a chip so you always know who you're talking to.
Purr-fect Proportions. Choose the aspect ratio for images you generate, from square to wide to tall. 2.0.2 Aug 10 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. 2.0.1 Jul 7 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. 2.0.0 Jun 30 Loading Times Get the Cat's Cream - We've paw-lished the app's startup so it loads faster and gets you purring along sooner. 1.5.2 Jun 24 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. 1.5.1 Jun 16 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! 1.5.0 Jun 1 Purr-fect Headphone Handoff - Plugging in or unplugging headphones mid-conversation no longer causes a cat-astrophic crash. Lumo now handles audio switches as gracefully as a cat landing on its feet.
iOS 17 Gets Nine Lives Back - Fixed a crash that cut off message sending on iOS 17 devices. Lumo now delivers your words without burning through any of those precious nine lives.
Auto-cat-rect Is Back - Autocorrection and spell checking are working again in the message composer. Your typos won't slip through the cat door anymore!
Sorry for all the puns :) 1.4.1 May 8 A Paw-some New Look - Lumo's composer has been rebuilt from scratch with a brand-new native interface on iPhone. Everything feels sleeker, snappier, and fur-tunately more intuitive than ever! 1.4.0 Apr 27 Paws Before You Speak! Fixed an issue where voice recordings weren't being transcribed into your message field. The timer was ticking but your words were stuck in the litter box, now they land paw-fectly in the input where they belong. 1.2.9 Apr 10 Return to Sender, Not Keyboard-ender, the return key now purr-fectly inserts a new line instead of rudely dismissing your keyboard mid-thought. 1.2.8 Mar 26 Widget Meow-calization Fixed - Widget strings are now properly bundled where they belong. No more translation cat-astrophes on your home screen widgets!
iPad Floating Keyboard De-clawed - Fixed that awkward blank space appearing when using the floating keyboard on iPad. Your layout is now as clean as a freshly groomed cat!
Tap Send, Keyboard Scram - The keyboard now politely retreats the moment you tap the send button. Less claw-tter, more chatter! 1.2.7 Mar 19 Dark Mode Icon - Fixed the app icon background in dark mode. No more mysterious shadows, Lumo now looks paw-fectly sharp on every
home screen!
Price Purr-cision - Fixed incorrect monthly price rounding on the subscriptions screen. What you see is now exactly what you pay, no more
fuzzy math, we promise! 1.2.6 Mar 13 Widget Tinting Fur-tunately Fixed - Widgets now render paw-perly in tinted mode, no more color cat-astrophes!

Dark Mode - For your 3 AM sessions (we don't judge)
Personalization Options - Make Lumo purr-fectly yours
Bug Fixes - Squashed some pesky bugs. They were fun to chase.
Now back to our scheduled nap. 1.2 10/15/2025 Updated translations.
Nothing particularly a-mew-sing :) 1.1.1 09/04/2025 Lumo's been busy... when not napping. Here's what we knocked off the table and onto your phone:
* Faster Loading - No more cat naps during startup! Lumo now loads faster than a cat running to the treat bag.
* Smarter AI - Fed our models premium kibble. Now 23% more intelligent and only occasionally ignores you on purpose.
* Better Speech - Fixed bug where everything sounded like hairballs. Speech recognition now understands human (most of the time).
* More Languages - Can now ignore you in more languages! Also fixed that thing where "Hello" kept translating to "Feed me."
Still judging your life choices, but with more purr-fessionalism. 1.1 08/21/2025 1.0 07/23/2025

Updated At: 2026-05-08

iPad Floating Keyboard De-clawed - Fixed that awkward blank space appearing when using the floating keyboard on iPad. Your layout is now as clean as a freshly groomed cat!

fuzzy math, we promise! 1.2.6 Mar 13 Widget Tinting Fur-tunately Fixed - Widgets now render paw-perly in tinted mode, no more color cat-astrophes!
