Edit time of mobile or email reminder



I'm wondering if there is a way to edit the time that you receive a mobile (SMS) or email reminder. Currently, it is set at 30 minutes prior to the event, which is great for some types of tasks, but I also want to be reminded at an exact time for other tasks.

An enormous amount of other tasks and things can come up in 30 minutes, and so by the time I want to complete the task, I may have gotten pushed onto another project, the message may already be buried under other emails or texts, or I may have even forgotten about the task entirely. A way to edit this for what works for each unique task would be greatly appreciated because 30 minutes is very unrealistic to apply to all types of tasks.

Thanks so much, again! =)

both absolute and relative reminders can be customized. For absolute reminders you can use any due date format supported by Todoist (even set up recurring reminders) and you can change the time before a deadline for relative reminders.

We've made a short instructional video illustrating how to to that, please take a look at it to see how it works:

Hello, David,

It looks like Im having an additional issue with mobile reminders. I've listed my mobile number (iPhone 4S, AT&T) in the reminders tab, but am not receiving reminders and am having difficulty even getting test messages.

For AT&T it says that I dont need to have a 1 in front of the number, but that doesn't work. So, I tried putting a 1 in front and an SMS did go through. I tried to send a second SMS to ensure it was still working and a second one was never delivered. I then tried to go back to without a 1 and that still didnt work. Next, I inserted a + in front of the one and that worked, but an attempt to receive a second SMS did not work with this either. Switching back to the 1 or without a 1 before the number didn't work after this. I've tried to re-send multiple times, and none of them work after the initial two.

Thanks for any help on this. =)

I am having this same problem,. I setup Preferences , and I have my important tasks to send text message. I do not even get the test text when I press that option in Preferences.
Thanks for your help.

Hello Susie,

please make sure that "Elsewhere (not in the list)" is selected as your location/provider and that you include your country and area code in your number without any spaces or dashes.

For example, if your country code would be 44, try the following combinations:

If neither works, please send your full phone number to david@doist.io and we will try to manually assign it to a different outgoing server.

Best regards,

Are the relative reminder windows a fixed set or can i set a reminder for 9 hours before the event?

Hello Jonathan,

The relative reminders can only be set to one of the pre-defined delays. If you want to use a different delay, please create an absolute reminder - these can be set to any specific date and time, for example, if you task is due "today at 18:00", you can set a reminder to "today at 9:00".

In case of absolute reminders, the task itself also doesn't need to have a due time or date.

How do absolute reminders work with recurring tasks? Does it only issue the reminder once at the specified time or does it figure out the relative difference for the next occurrence?

Absolute reminders are independent from the task's date, but they can also be recurring. For example, if the task is set to "every day", you can add a reminder set to "every day at 16:30", but then regardless of whether this task was completed or is overdue, you'll keep getting a reminder every day at 16:30, which in a way, can be very useful :-)
