What's New in 3sparks Chat

3.0.1

July 9, 2026

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.

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.

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.
