The Missing Link Between My AI and My Day
I use Claude to plan my entire schedule. Meds, training, client calls, wind down, all of it. Claude writes the day to my Google Calendar and that used to be where the system broke, because iOS calendar notifications are useless. Quiet banners you swipe away without looking. I had a perfect schedule sitting in my calendar and still missed half of it. OnTimer fixed it.
It reads my calendar and automatically creates a real alarm for every event. Not a notification. A loud alarm that actually cuts through. I don’t build alarms manually. I don’t maintain two systems. Claude writes the plan, OnTimer turns it into sound, and I just live my day. If you searched “Google Calendar to iPhone alarm,” “convert calendar to alarms,” “AI calendar alarm,” “Claude calendar sync,” or “ADHD calendar alarm app,” this is it.
The developer is also a real human (I won’t say his name for privacy) who actually cares. Responsive, fast, works the problem with you, ships fixes. Almost extinct in the App Store right now. Setup took two minutes. Loud alarms. Customizable lead time. If you use AI to plan your life and you’re on iPhone, OnTimer is the piece that closes the loop.

Keeps me on time
My grandfather always told me that if you’re on time, you’re five minutes late. Ontimer make sure that I’m never on time but rather early and impress my meeting.

My coworkers no longer harass me for being late
Good stuff!
Simple to use, effective, and fills a niche. Good stuff!

Perfect
Exactly what i needed to keep on time
Great app for staying on time.
Super easy to set up and connect to calendars. And the alerts are just in your face and persistent enough so that you won’t be late.
The new update has a cool time to leave feature. So if your events have locations you can get an automatic alert based on traffic and distance. Pretty cool.

As advertised
This app is great. It has definitely helped me to “never be late.”
A great app!
App does exactly what it claims in a simple, quick and elegant way. Especially for someone like me who has multiple meetings and various arrangements across multiple calendars it was a breeze to setup and keep me well organized so I don’t miss anything scheduled.
