Claude on iOS can be your assistant
Claude can work with Reminders, Calendars, Maps, Messages and more
I missed the big news that Claude for iOS can work with the iPhone and do magical things with your Reminders, Calendars, Maps, Messages and more. In a recent update Claude enabled these super powers making it the best way to do productivity things with the data on your iPhone.
In addition, the new Claude Sonnet 4.5 Model is simply the best LLM I have used. It’s my daily driver for coding tasks and a great general purpose LLM. I find it to be less verbose than GPT-5 and quicker to respond.
I wanted to illustrate an example scenario I used Claude for making really feel like an assistant. Something Siri and ChatGPT cannot yet do.
Prompt
I want to go to breakfast with my son on Saturday. Can you check when Hi-Spot is open and create an appointment on my calendar and then draft a message for me to send Miles.

Drafts a Message to send him via iMessage
Now, like any LLM or assistant it did not use all the context correctly. I need to drop off my son at 10:30 for a UW Game. So I reply back with:

Is that enough time before he gets picked up for the UW game

This is impressive. It’s like a real assistant. I’ve been waiting for this for a long time and it’s so great to have it.
