It is surprising that the Claude web app lags pretty easily when using either chromium or firefox on ubuntu linux. Chats that delay my laptop work without issues on my ipad or iphone using the app.
The web app is definitely a bit of a problem. IF there is a native app on desktop or if claude cli is much faster, i haven't tried them.
All of the LLM web interfaces have serious lag when typing after a few turns, at least on iOS safari. I’m talking seconds to start rendering input after typing or when it needs to line wrap the input.
The Codex app slows to a crawl after a few back and forths. In fact it’s so bad that I had to completely switch to CLI, where at least it’s the optimized terminal that takes care of the rendering rather than whatever monstrous electron scaffolding they use
