Reminders can be great tools for people with ADD / ADHD. Our SmartPhones have a whole bunch of apps to remind us. We can also set our own email reminders and calendar reminders. Until we start ingoring our reminders they are great. I recently came across a great reminder service called Snoozester.
Snoozester provides the same type of Wake-up calls and reminders you get when you stay at a hotel. What I love about the Snoozester Wake-Up Call is that you can SNOOZE it. It will call you back until you tell it not to.
Another feature I love is that you can choose different voices for your reminders. You can also choose Random so you will be surprised by which voice will be giving you the reminder. I think the variety is great for people with ADD / ADHD.
Snoozester offers different pricing plans that start at $3.99 but there is also a FREE Trial. Snoozester gives you 10 FREE Credits to try the service. You don't even need to sign up with a credit card or give them any other payment info to try it for free.
You really have nothing to loose by trying out Snoozester. If you don't want to give them your phone number you could even use something like Google Voice.
Yes, I am currently a Snoozester user myself and I LOVE it!
