Private LLM is a better alternative to generic llama.cpp and MLX wrappers apps like Enchanted, Ollama, LLM Farm, LM Studio, Locally AI, RecurseChat, etc on three fronts: 
1. Private LLM uses a faster and highly-optimized mlc-llm based inference engine.
2. Models in Private LLM are quantized using the state of the art quantization algorithms like OmniQuant, while competing apps use naive round-to-nearest quantization.
3. Private LLM is a fully native app built using C++, Metal and Swift with deep integrations with iOS and iPadOS, while many of the competing apps are bloated and non-native Electron or Flutter based apps.

Please note that Private LLM only supports inference with text based LLMs. Model support varies by device capabilities.

### 1/5 — Not functional

*2026-08-06, version 1.9.15*

Absolute trash. Does not work as AI. It’s unable to answer your questions and is unable to proofread or verify information. Absolute trash.

### 1/5 — Don’t waste your money

*2026-07-25, version 1.9.15*

It doesn’t work on my iPhone, just loops endlessly or generates never-ending #s

### 1/5 — doesn’t save conversation history

*2026-07-21, version 1.9.15*

which is the entire point of using local ai instead of just using an online one without logging in.  waste of $5 :/

also, the app is significantly less useful than other ai since it can’t do web search

### 1/5 — Models keep freezing

*2026-07-21, version 1.9.15*

Most models keep freezing during download or when a model downloads it wont load and the app crashes now thinking of it any model beside the preinstalled model don’t work. Help

### 1/5 — Not worth it

*2026-07-17, version 1.9.15*

There is no updates for over a year with new Model.Bbeing paid app its not worth it.  Other similar app LOCALLY is lot beterr as free app but better models which updated regularly.

### 1/5 — C’est pire que prévu ! À faire tant que rien est fait!!!

*2026-07-08*

Ça Chauffe! … Y’a pas à dire, le site Web est bien fait. Par rapport aux autres applications que j’ai pu tester et utiliser, c’est bien la pire ou la plus compliquée à comprendre ! Il me répond toujours à côté. J’ai vraiment l’impression d’avoir été trompé, arnaqué ! Pourquoi Apple laisse cela sur l’App. Store, sont-ils complices???

### 1/5 — Crashes a lot and doesn’t save work

*2026-07-05, version 1.9.12*

Hot garbage

### 1/5 — 不满意

*2026-07-01*

感觉甚至有点诈骗的意味，国内下载不了任何的模型之前说过会更新的，但是现在没有任何声音

### 5/5 — Amazing!!

*2026-06-30, version 1.9.12*

The built in models have a greatly varied selection that are perfect for all different tasks!! The override function lets you really make the model your own.

10/10 would recommend

### 4/5 — It’s a little buggy

*2026-06-27, version 1.9.12*

Don’t get me wrong this is the absolute best app for offline LLM in the App Store it’s just buggy and If you put to long of a system prompt in then it will crash
