Does anyone have tips for time blindness? I always underestimate time

The Tiimo app has a routine manager, and a visual timer on it. The app was designed for time blindness

YouTube visual timers. They’re amazing. Also start doing what feels like overestimating how long it will take you to get ready/get there. Like if you used to say “10 minutes to get ready” say 20 minutes instead and set the timer. GPS the address, even if you know the way, (if your appointment is somewhere else) and add it to your timer. If you don’t have Alexa, get one. Sync her to your phone calendar. She will remind you of appointments (weeks, days, hours or minutes out) if you have reminders set in the calendar event. Calendars app by readdle is my favorite because you can color code, and you can see up to like 5 events a day in month view.

okay so what i do is overestimate the time like CRAZYYYY. like i will seriously give myself 4 hours to get ready or do anything really where i used to give myself about 30 minutes. i still don’t understand the difference between the two, but this insane overestimation works well !! and now i’m actually early (shocking - my family has screamed at me all my life for being late (sad face😭)) to things! now they are impressed with me. :)

When I need to be somewhere at a certain time, I schedule it in my calendar 15 - 30 min early. To "trick" myself into extra buffer time. Setting multiple alarms and reminders can help as well; label them so you know what they are for. I picked up an adhd friendly kitchen timer with the timer part a distinct color. It helps to "see" the time passing while doing chores and such.

Time yourself on your most frequent tasks and use an analogic watch so you can see the time passing

I treat transitions between what I’m doing to the next task as important as the task. I plan in “travel time” for every thing. In other words if I have to be at work at 9. I treat it as I have to be at work at 8:30, so that if I go time blind I built in half an hour of “extra time”

I’m late to work almost every day despite being aware of why…I set alarms on my phone and everything
