THE BEST

这是我在app store见过的最好的api client,美观,完全免费,功能齐全,方便实用。
给个建议:1 UI方面还需要改进,主要在文本框有些有奇怪的bug

THE BEST!

The app almost has every feature you’d expect. It’s highly customizable and runs like butter. Can’t believe the developer stuffed so many functions in while making it this small in size. And the design language aligns with Apple perfectly. Definitely a must-have if you want to use your own api keys

Response from developer

"Runs like butter"... love your turn of phrase! Thanks very much for your review 😃🧈

Perfect for local AI

I tried several apps before I found this to connect to a model I host on my own hardware. I almost thought I would have to build it myself. This is exactly what I wanted to build!

Response from developer

Glad you like the app. And thanks so much for your review!

Plagued with analytics: app-analytics-services.com gets hammered.

Constant Firebase analytics outbound connections.

Small developers have become the new surveillance dark horses, more dangerous than big tech, because we trusted them.

Shame on you.

Response from developer

I use Google Analytics for Firebase to collect limited information about which Cumbersome features people use. This helps me understand what's useful and where to focus improvements. Your conversations and other private content are never sent to analytics. As of version 1.72.0, you can disable analytics entirely by turning off "Share Usage Analytics" in Settings > App.

Exactly what I wanted

Great job Peter. I’ve only been using the app for a couple of days, but it’s exactly what I wanted and was very easy to set up.

Not coding plan

Not z.ai coding plan

The Perfect Blend

This LLM client’s approach is the perfect blend of simplicity and complexity. For example, it’s simple and has a straightforward conversation history but an individual chat can easily be exported in full JSON for another agent to use if you need to take a conversation to the next level. Or how it uses iCloud for seamless sync. Peter rocks!

My favourite AI app in iOS

Let’s you use Ollama Cloud and Open Router so you can switch between models at will.

Web search supported well with both and the app has been improving really fast since I started using it.

No macOS 15 local search support?

Everything is great except for no macOS 15 local search support. Is this a technical limitation?

Response from developer

Thanks for the feedback. As a one-person development team, I have to balance broader compatibility against development and maintenance time. Local web search currently relies on Apple’s native WebView and WebPage APIs introduced in macOS 26, including support for headless browsing. Supporting macOS 15 would require a substantial second implementation. It was relatively straightforward in 26 with the new APIs from Apple... it would be a heavy engineering lift for legacy support, unfortunately.

Best phone llm source

Clean design, just works. I supplied a openrouter key. PDF parsing works perfectly, as well as browser use. Installed it on my MBP too, and found all my chats. I use it more than claude now

优势是免费、手机电脑同步

轻量化、清晰顺滑、免费、接入友好。有几个小缺憾:1. 长文本输入输出的时候有概率出现滑动卡顿、闪屏、显示故障。2. 侧栏 ui 的颜色有些刺眼,对于一个大量阅读的 app 来说最好还是配色风格温和专业一些。3. 添加 provider 之后无法修改,调试换端点稍有点麻烦,但问题不大。

Response from developer

Thanks for the detailed feedback. I will add a theme picker so you can adjust the colors, and I'm working on the scrolling and display glitches. I'll also look into making providers editable.

Just the right amount of complexity

Reading the history of this developer (hi, Peter!), I shouldn’t be surprised at how well this app is put together. It integrates complexity very well. It thoughtfully fills gaps between what models offer and clients typically provide. Plus it’s just really (really) fast to start and sync.

Response from developer

I'm glad someone read the About section on Settings! Thanks for your kind review.

Exactly what I needed

I’ve been using this app since it came out. I’ve long wished for certain features and hoped for continued updates. It’s worked fine, however, the past 5 versions or so have finally given me the features I’ve been waiting for the whole time and it’s amazing. Separate system prompts, chat scoped system prompts,, toggleable parameters, more fixes to the streaming text Views, all the newer OpenRouter backend tool support. He even added COMPACTION! That’s amazing! Thank you so much! Love this app.

Thanks very much for your review! Email us feature requests and bugs... We're continuing to push out code! We also have some novel interfaces that we hope to get to soon.

Simply outstanding

The future of AI is with API key usage. Cumbersome does that flawlessly. I’ve brought my monthly AI costs through subs down from 30$ a month to 5$ every few months using open router. It really doesn’t get better than this.

Excellent LLM client

I’ve been using local LLMs through openwebui for a while, but the lack of a proper iPad client makes the usability hard. Cumbersome is an excellent alternative to being able to access models you host on your own network. If you use VPN or tailscale, you’ll always have access to these models.

REGENARATION

pls pls pls add a regeneration feature

Response from developer

I think we have this feature already? Long-click on your most recent message in a convo and select "Restart from here." This will regenerate the last AI response. Send me an email if you mean something different.

Amazing

This is the best AI (API) app on the App Store. After weeks of searching and dealing with countless issues in other apps, I finally found one that gets everything right.

Very awesome, but..

The app itself is pretty cool! And very nice and easy to use for Local LLMs, but I do have an issue.. some APIs actually provide free-to-use, with no api key required… and the app needs an API key, so im asking if we can get update to make it not needed or whatever.

Overall, Thanks!

Response from developer

Keyless is now available in >= 1.49.0

Great app!

I have looked around for different LLM API Clients for a while now and this one is definitely the best one I’ve tried by far. It has sync with iCloud so I can use it with my Mac, headless search (didn’t even know that was possible), and easy access to all the models you want (I use DeepInfra). Honestly can’t believe you give it away for free but I’m glad you do :)
