Long Time User | keep up the good work!

I pay for Grok, ChatGPT Pro, and Claude, and on my M5 Pro I run models locally(mlx).

But Private LLM is still the app I open when I’m camping, or when I don’t want a prompt leaving the device.

On-device inference is SICKKK, and I like how the models are cleaned up so they run better on iPhone, not just dropped in. The quality gains are (IMO) noticeable.

My asks:
Wider catalog & access to newer models.

Fonts -> add some customization Newsreader 👀

The UI could use love but its functionality over form.

Most ignorant AI ever.

Thankfully it was only $5. I get better from free ChatGPT. Need an example. It wrote this. Chapter 1: Moving to Dallas from Barcelona

Alexander Sanchez, a friendly and helpful AI assistant named TinyLlama, arrived at 12002 Timberlake Court in Dallas, Texas on July 3rd. The four-bedroom, four-and-a-half-bath home was the largest house in its neighborhood, with over four thousand square feet of living space. Alex's new home was situated just over four thousand square feet in size, making it more than twice as large as his previous residence in Barcelona, Spain. Its two-story structure was impressive, with high ceilings and ornate molding, which complemented its Spanish-style design. The house was surrounded by lush landscaping, including a koi pond, towering trees, and a manicured lawn. Alex could hardly believe his luck in finding such a magnificent property for him to call home. He couldn't wait to move into his new home and finally find something better to occupy himself with. With his family's support, he had purchased the property, just over four years ago, with funds from his parents' well-established business, King Industries. Despite the potential challenges ahead, Alex felt confident that they would make it work out, and he was ready to take on their new headquarters in North America. As Alex moved into his new home, he noticed the new property's impeccable amenities - such as the swimming pool, hot tub, and guest house on the premises. The home was luxurious, with plenty of space and amenities to accommodate his family's needs, while also offering ample room for him to thrive in the fast-paced world of business. Alex felt grateful to have found such an excellent place to settle down, both in terms of proximity to the city center and the vast opportunities it provided. With his family's support, he knew that the transition to life in North America was going to be smooth, as the company's revenue and growth continued to soar. His family's wealth had given him access to resources and opportunities that made it possible to start anew in Dallas. Despite his initial excitement about moving to a new location, Alex still had some adjustments to make. For starters, he needed to learn the layout of the city, navigate the various roadways, and. I replied with “Remove this “a friendly and helpful AI assistant named TinyLlama” and rewrite please.” What did it do. Just repeated itself. Chapter 1: Moving to Dallas from Barcelona

I love this app

This is a great app I really enjoy it I’m so happy I found it

Amazing AI app, works with voiceover, but needs newer models

This is an awesome app that lets me do anything an AI can do, summarize text, generate entertaining story content, coding work in Python, and more - all with proper VoiceOver support, which matters to the visually impaired. The only thing I ask is for more, newer models, E.G. Gemma 4, Qwen 3.5, ETC, and the ability to snap a photo and have it processed by the model's vision capabilities. This would be a game changer for individuals with disabilities.

Not worth the $5…

All the models on this app are pre-selected with no way to actually connect to a local OpenAI API endpoint or run your own downloaded models from huggingface. It’s like this app hasn’t been touched or updated in well over a year. This should be a. Free app, not a paid one. If it was free I wouldn’t have expected more from it. But $5 is too much and maybe $0.99 would have been more fair but in reality it should have just been free. Do not recommend.

Better options exist

The “developers” solution to fixing their problems isn’t that they fix their code, it’s to drop support for older iPhones. What a joke. They’ll claim it’s because it’s all evolving so quickly, but their planned obsolescence of software for perfectly working phones because they’re incapable of writing software is laughable. If it was OSS, I wouldn’t have bothered writing any of this, but it’s a paid app. My recommendation is to grab PocketPal or Locally. Don’t waste your money on this. Locally has a poor UI and other limitations like that it doesn’t warn you that conversations will be cut off before you hit the context limit. PocketPal requires you to understand how models work, what to download, and what defaults you should change (and their pal system is a “system prompts in a box”, except that customization is painful and json customizations don’t work). But at least with Locally my phone doesn’t turn into a furnace and with PocketPal I can tweak the things that matter. PrivateLLM however offers none of the stability of Locally and none of the customizations of PocketPal. It’s a paid llama.cpp interface with poor context management and limited model selection. Now it’s in a crash loop because the model got into a fit yammering on and on and I have to uninstall it and reinstall it now. Oh and you only get one chat. Yep, one. No separate contexts for each chat, no separate system prompt for each model. Nope. You get a limited system of compromises that don’t work for $5. First app I’ve bought off the App Store in years and I’m reminded why I stopped bothering when the bar is so low. Their best feature is a unique quantization method, but that doesn’t matter if it doesn’t run.

Outdated

The curated models are seriously out of date.

模型不能下载

模型在国内还是下载不了 总是在0不动 不是说是自己的服务器吗 为什么还是在hug上..

Not functional

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

Don’t waste your money

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

doesn’t save conversation history

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

Models keep freezing

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

Not worth it

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.

C’est pire que prévu ! À faire tant que rien est fait!!!

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???

Response from developer

« Ça chauffe » : c'est exactement ce que fait l'IA locale. Le modèle tourne sur le processeur de votre iPhone, pas sur nos serveurs. C'est votre appareil qui fournit le calcul — il chauffe donc, et il est limité par sa RAM. Aucune app locale n'y échappe. C'est aussi pourquoi les réponses tombent à côté. Sur un iPhone ancien, seuls les plus petits modèles sont proposés, et un modèle de 1B ne raisonne pas comme un 8B. Si votre appareil a basculé sur le modèle intégré après un échec de chargement, la qualité chute encore. Ouvrez la liste des modèles et choisissez le plus grand que votre iPhone accepte : la différence est nette. Les prérequis matériels sont détaillés sur privatellm.app/fr/faq, section « Appareils et modèles ». Apple n'y est pour rien — la contrainte est physique. Si votre iPhone n'est pas à la hauteur, demandez un remboursement à Apple : historique des achats → Signaler un problème. La marche à suivre est dans « Achat et remboursements ». La prochaine version majeure relèvera la configuration minimale et abandonnera les iPhone trop anciens, précisément pour éviter ce genre de déception.

Crashes a lot and doesn’t save work

Hot garbage

不满意

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

Response from developer

你说得对,这确实是我们的问题。之前的版本在中国大陆下载不了模型,原因是模型托管在 Hugging Face,而 Hugging Face 在国内无法访问。 最新版本改了下载方式:模型现在从我们自己的服务器下载,不再依赖 Hugging Face,国内可以正常下载。请更新到最新版本再试一次。 修复其实已经发布了,但我们没有回来告诉你,让你一直等着。这一点我们做得不对。 如果你不想再折腾:可以直接申请退款。在 App Store 的购买记录里选择"报告问题"(Report a Problem),由 Apple 处理;退款说明见 privatellm.app/faq 的 Purchase & refunds 一节。一个用不上的 App 留着没意义,退款比留着更合理。

Amazing!!

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

It’s a little buggy

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

Useless app for $4.99

I saw a YouTube video of the developer describing how to use it. Followed the instructions to start generating images. The first issue right away is it’s asking $4.99 just to use it. No mentioning this on the description whatsoever. I bought it to try the image generator. Loaded some models, no button to generate images. I’m disappointed I wasn’t my $5 for a useless app.

Limited usecase

Can't download models from HuggingFace like others let you do. Purely local and has curated models to pick from.
