iPhone AI apps have one real edge: Shortcuts, widgets, Siri. The AI comes to you instead of making you open another app. That matters more than any feature list. - Daily drivers first: the ChatGPT, Claude, Gemini, and Copilot apps all have solid iOS versions. If the team uses none of them on mobile, fix that before buying anything exotic. - Audit your stack before adding. An AI tool stack audit app pays for itself here: most people discover they already pay for three apps doing the same job. - The winning setup is boring: one assistant app, one notes app, one automation app. Three apps used daily beats eleven forgotten. - Watch subscription traps: iOS makes subscribing easy and canceling forgettable. Check quarterly. Compare iOS AI apps by workflow and real pricing tier, and PrivateLLM deploy sets up a private LLM on AWS for $50 plus usage for teams that want it on their own servers.
