## What is Spike Studio?

Meet Spike Studio: AI chat on your iPhone, with a choice of where your model runs.

GET STARTED WITH SPIKE CLOUD
Create a free account in the app, verify your email, and start chatting. You do not need a computer or your own server. Free usage limits apply. This version offers no in-app subscriptions or purchases.

USE YOUR OWN MODELS
Connect an OpenAI-compatible server, including LM Studio, or download an on-device model on a supported iPhone. These options do not require a Spike account. Model downloads need available storage, and on-device performance depends on your iPhone and the selected model.

CONNECT YOUR COMPUTER
Use an account-linked Runtime from Spike Studio on your computer, and follow Agent work from your iPhone. Computer and Runtime setup are required for these optional features.

KEEP YOUR CONVERSATIONS TOGETHER
Sign in with the same Spike account across devices to sync encrypted conversations. Organize chats in projects and choose tools for the task at hand. Tools that use iPhone features request the relevant permissions.

Cloud chats are processed by Spike Cloud; on-device models run on your iPhone; a connected server processes the chats you send to it. Choose the option that fits your needs.

## Key features

- Run AI models locally
- No cloud dependence
- Private data processing
- Zero cloud costs
- Unlimited model usage
- Instant responses

### 4/5 — Good but…

*2026-09-02*

It takes a really long time to answer questions

**Developer response:** Thank you for your feedback! If you’re using an On‑Device model, try the smaller Spike 2B model for faster responses. Also enable only the tools you need in the Quick Menu—larger models and more active tools require more processing and can make answers take longer. We’re continuing to improve performance and make these choices clearer in the app.

### 1/5 — No Response

*2026-08-06*

I can’t get a response from this app. It just sits there.

**Developer response:** Sorry—Spike should not have just sat there. In version 1.6.5, messages could be sent without a configured model source, and the connection error was sometimes hidden instead of explaining what was missing. Spike requires either a configured server or a downloaded On-Device model. We appreciate you bringing this to our attention.

### 1/5 — Nothing Loads; Slow AI replies

*2026-08-01*

It would’ve been ok, if the response and replies don’t take 7+ minutes for the AI to generate an answer. Thats kind of ridiculous.

**Developer response:** You’re right—waiting seven minutes for a reply is far too long. This version can run AI entirely on the iPhone, and larger On-Device models may be very slow depending on the device. Selecting a smaller compatible model should improve performance, but the app should have explained that tradeoff much more clearly. Thank you for the feedback.

### 5/5 — Tools, MLX, and Voice Chat!

*2026-05-29*

This is one of very few free apps offering so many great features for fully local LLMs. Nice clean interface, supports MLX, tons of tools. Soprano TTS and Qwen ASR!

### 4/5 — Not Bad

*2026-05-13*

You guys are off to a good start and you probably have the best client app on iOS. That being said, I have one major gripe people do a lot of research and document creation with AI that should’ve been one of the core aspects of the app.. But that turned out to be the Achilles heel of the app.

You checked every other box except for that one.. And it would be nice if you also added MCP Tools. Can we make this app more like a mobile agent?

### 5/5 — The best app I’ve found

*2026-03-10*

I run a local LLM on my Mac Studio. This is by FAR the best app I’ve found to connect remotely. It just works! And supports so many functions.

Wish there was a better way to contact the dev. The app has some performance issues such as lag and it would be nice to change the default icon.

Also it would be nice to see some feedback from the server. Such as if it’s actual loading or stuck.
