5 Nov 2025 EditAfter the iOS 26.1 update and the last Lumo update, the below problem is resolved. Note: The GPT4.0 still gives fake data and fake references. But that's everywhere. Updated stars from 2 to 4.-----Original: iPhone 13, upgraded to iOS 3-4 days ago. All apps in app store updated as of 09:00 (GMT -4). After asking a question, keyboard can be "dismissed" but the UI never readjusts, so Lumo and all its windows/panels take up just 1/3 of the phone, leaving a blank 2/3 "white space". The entire conversation has to occur in a 2" box with a 2-line reading window. I've tried logging out/in and reinstalling. "Help/Settings" also becomes totally unresponsive.Will edit stars and review when fixed.As for the LLM, it's workable on my regular Pro sub for the few questions as I am a heavy Proton user but not a heavy AI / LLM user. I do not find it worth an additional subscription and would simply use another product if locked out of Lumo on a paid Pro (non-AI sub) basis.

During my very first use of this app immediately upon installing, it became apparent that reading responses would be nigh impossible. Why? Because while the keyboard disappeared upon sending my request, the space it took failed to collapse, reducing the space available to display the response to a mere 6 lines of text. Additionally, a button overlayed the response text. Its purpose seems to be to scroll down to the end of the response. Unfortunately it made it impossible to reach the text displayed next to it, for the purpose of scrolling. So the only area that would respond to scrolling exists above that button-a mere three (3) lines of text. Imagine having to scroll through several paragraphs of a response when you can see only 6 lines at a time, and can use but 3 of them to scroll through the remainder. An utter usability disaster, this app does not lend itself to be used for anything serious, it its current state.

let me preface by saying, I have never used any of the other AI's. None of them. And I didn't try this until the big update. And I've only probably used it 10 to 15 times, though many of those were extensive. And I did not use it for anything one might consider 'creative.' So in my expert opinion, it's totally worth it. I used it for some real estate analysis, and was able to get both great summaries and great detail, all backed up by links that had even more worthwhile information. it wasn't sycophantic, and acknowledged gray areas I would point out in some of their responses. getting that under a veil of privacy is something I'm so far very happy to pay for it.

Update: My initial review was pretty harsh, but Lumo really was playing it too safe to be useful. Lately it is pretty good for creative tasks even if somewhat sensitive topics are involved.The safeguards on this are extremely strict, to an extent where even harmless inquiries result in the “can’t help with that” response. I understand the desire to prevent LLMs from being misused, but the current state of Lumo is absurd. Is it because of the EU being a pathetic joke that brings shame to the concept of a democratic society? What’s next, will I need to provide my digital ID to use my “confidential” AI assistant? What a joke.
