What's New in 3sparks Chat

3.2

August 30, 2026

Pin the chats you use every day to the top of the list. Speak your messages with dictation, and have replies read back to you. Claude models can now think before answering, with the thinking shown separately from the reply. Start a chat or send a message from Shortcuts, Siri, or the Action button. Download any public Hugging Face model, not just the curated catalog. Paste a model ID or URL and pick the file you want. Also in this release: - Connections show their provider's logo, and every list in the app now shares one design - On iPad, Return sends and Shift+Return starts a new line - The "local model not loaded" notice can be dismissed - A connection missing its API key now says so - Timestamps no longer tick once a second Fixes: - Turning off memory for a chat now sticks - Deleting a chat's messages also clears what was remembered from them - Switching to a model that cannot reason no longer strands the setting - Sending works again as soon as you are back online - Quitting mid-save no longer loses a message

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.
