### 2/5 — Updates = Broken

*2026-07-03*

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.

### 5/5 — Intuitive and great support

*2026-06-07*

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

### 5/5 — Works great with local LM Studio

*2026-04-26*

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.

### 3/5 — Only Englisch keyboard layout

*2026-04-07*

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

### 4/5 — Useful remote chat

*2026-01-27*

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.

### 1/5 — Save your money!

*2025-12-10*

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.

**Developer response:** Hi there, please reach out from the help menu in app and I can help you figure out what’s wrong.

### 5/5 — Works

*2025-09-18*

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

### 1/5 — Stay away from this app

*2025-08-17*

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

**Developer response:** Hi there, our app doesn’t offer any subscriptions. If you’d like a refund, you can contact Apple, and they’ll be happy to process it for your purchase.

### 3/5 — Not worth the money

*2025-06-21, version 2.5*

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.

### 4/5 — Great start, but needs more features.

*2025-06-15*

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.

## Version history (last 5 releases)

### 3.1.0 — 2026-08-17

3.1.0 makes local AI chats more resilient and gives model browsing one consistent, cleaner look.

• Generations keep streaming in the background on iOS 26 and later — leave the app mid-reply and come back minutes later to a finished answer, with a system indicator showing how long it has been running
• Redesigned LM Studio model picker: your current model and its reasoning setting up top, alternatives visible at a glance, and search, filters, and refresh in the toolbar 
• One consistent design across the model picker, LM Studio management, and Local Models, with provider logos that ship in the app and work offline 
• Download Hugging Face models on your LM studio server from 3sparks Chat by pasting either a full repository URL or a copied model ID 
• Reasoning levels are available right in the model picker and stay applied across requests 
• Cleaner chat header with the active model shown as a compact subtitle 
• Message actions stay out of the way while a response streams, then appear smoothly 
• Faster and more accurate model refreshes 
• Fixed: archiving every chat left an empty screen with no way forward 
• Fixed: unreliable model switching, accidental duplicate model loads, and crashes from duplicate model records 
• Fixed: clearer messages when models fail to load or a server returns an empty response

### 3.0.1 — 2026-07-09

Sync That Doesn't Cry Wolf
Fewer "Chat Diverged" warnings: Regenerating a response no longer triggers a false sync-conflict warning, and a real conflict warning now opens a sheet that actually shows the conflict.

Better Error Messages
No more silent "Generation stopped": When a request fails — wrong API key, server out of memory, a model crashing mid-load — the app now tells you exactly what happened instead of showing an empty response.
MCP failures identified: A failing MCP tool integration is reported as a tool problem, not a false "server offline" notice.

MCP Server Fixes
Auth headers that stick: Adding an API key header to an MCP server now saves reliably — typed headers are included on Save, and the Save button re-enables after edits.
Connection edits reach every chat: Fixing an MCP server's URL or key on the connection now applies to existing chats too, and no longer shows duplicate servers in the + menu.
Toggles look like toggles: MCP servers in the + menu show a checkmark when enabled again.

### 3.0.0 — 2026-07-01

3.0.0 is a major update focused on private, on-device AI and stronger local-model workflows.

• Run supported GGUF models directly on your iPhone or iPad with new Local Model connections
• Browse curated and Hugging Face local models, including supported vision models with projector downloads
• Use private on-device Memory to save and recall helpful context from chats and documents
• Choose per-connection defaults for Memory and instructions when starting new chats
• Start private chats that never read from or save to Memory
• Improved LM Studio v1 support, including reasoning/context settings, model loading controls, image requests, MCP tools, and reconnect behavior
• Regenerate failed responses without duplicate messages
• Added offline LaTeX rendering, better Mermaid spacing, expanded About details, and many release-readiness fixes

### 2.8.4 — 2026-05-14

-Bug fixes

### 2.8.3 — 2026-04-22

- Improved connection check
- Bug fixes
