Works great with LM Studio

I have LM Studio on a private VPN. Works great with authentication enabled in LMS. Would be nice to support compaction. e.g. I have 200k context available and compaction could open a new chat that is compacted to 30k tokens with 40k most recent tokens remembered. For example, "new" compacted chat would "start" over with 70k tokens (30k summary with 40k recent preserved as literal text from previous chat (ok to have a nonsensical cutoff). Compaction should be per-connection configurable. Per model is even better buy per connection is still great and easier to implement.

Updates = Broken

Every time we get an update, more things get broken. Now the app freezes and locks up during chats… you have to close the app and restart it, and your last prompt is gone and you have to redo everything. Can’t use it like this.

Intuitive and great support

Secure, easy to use with great features. Very good value for money.

Works great with local LM Studio

The developer seems to be constantly improving the app and for me it meets many of my used case needs with a back in connection to LM studio.

I very much appreciate the image enablement.

Only Englisch keyboard layout

The language and layout could be also in German for exampel.

Useful remote chat

Easy-to-use app to connect your iPhone to the local LM Studio server. Especially nice is its ability to save and use different system prompts from within the app.

Save your money!

After a week still can’t get it to work, while others chat apps have no problem with my server, waste of time and money.

Works

Connection was a breeze with LM Studio and Tailscale. Please consder incorporating audio input for prompting.

Stay away from this app

I just got charged by this. I cannot cancel a subscription and there is no way to do this in the app either.

Not worth the money

Does not work in prohibited countries without VPN. Anthropic does not support the latest models, although there is a «Fetch models» button. After a couple of messages, LLM stopped responding and then the chat history stopped loading at all.

Great start, but needs more features.

Great job overall. However, a few things are really annoying. The default token limit is too small. I’d like to set the default per connection. Another annoying one is that Gemini doesn’t use grounding. Please enable Search grounding for Gemini models. The last annoying thing is that there’s no iOS Live Activity corresponding to running queries. It’s really annoying to have to keep the app open for the query to not be interrupted.

Local PDF access

So far works very well and was able to provide a picture to a local model that understands pictures. Also was able to provide a PDF via web URL link. But choosing Text file cannot provide local PDFs. Adding an option to provide local PDF files and drag and drop of files into the chat would be a great option!

Still no backgrounding

I don't use this app, I wasted my money on it. Buy LATENT CHAT if you want backgrounding for your LLM. This developer acts like her cares by adding useless functionality like web to RAG, but u can just download a pdf and rag that in latent chat so it does the same thing, BUT as soon as you leave this app your prompt and the response WILL ERASE WHILE STREAMING. This is not ideal for large contexts and slow LLM responses, and this guy thought he could jam in vision enabled (analyze image input) without any repercussions. So that image adding function is basically useless if you expect a long response for an LLM that utilizes your full GPU offload, and if you accidentally leave the app you can kiss your maximum effort prompt you worked on prompt bye bye! 👋

TL;DR: I see right through this gimmicky update, its not worth it until he adds backgrounding while streaming responses. Otherwise it's ok if you just need very basic text response where you are stuck inside the app and cannot leave.

😘yw for the feedback😘

No backgrounding, No image input, No web search

An app 4 years and it's still unable to do what every one of it's android competitors can? This doesn't seem legit to me at all.

Great for text! Hoping it will support all modalities in the near future!

Great for text only convos. I just wish it supported image & video input and outputs.

Cannot set defaults

You can’t set default instructions, skip the setup and use the server-side system prompt, or choose a default model. There’s no way to lock in default settings like temperature, context window, or streaming mode. Way too limited for power users.

Excellent app, excellent customer support

I had problems at first, developer responded and fixed it asap. Impressive! The app is exactly what I wanted. Highly recommend. Thanks!!

Update April 17, 2025: this app is wonderful. I use it to connect to LLM’s on my Mac mini. Dev is putting out updates weekly, adding a lot of features. Wow. Very impressed!

Timeouts make it unusable for me

I use this with a Llama 70b model with Ollama server, which can respond slowly but that's fine for my purposes... after a couple of initial successful LLM text responses I start receiving "LLM is running slowly..." errors. It never recovers. The problem is persistent. The app will get better and better, but for now the timeout issue makes it unusable.

Fantastic app and great dev

I use this app daily for the integration with LM Studio in which I can host my own LLM's in LM Studio and then access them via this app on my cell or iPad for chat capabilities, which works perfectly. Also I have given several suggestions to the Dev and he always is very responsive and dedicated to making this app the most useful it can be by adding additional features.

Awesome

Love this app, the keyboard is great.
I think its great thats its one price and not another subscription.

The chats just needs RAG and web search and also live camera OCR and image gen would be nice. I would gladly pay for these as in-app add-ons
