Easy to use and configurable in many ways. Widgets, too. I downloaded this app several years ago and have never regretted it. It synchronises with the matching tasks app very nicely. TBH, I can't remember whether I paid for the full version or not, but it's worth it, either way. The default calendar on my phone is also fine, but I just wouldn't use it now.

I like this app. But! Before it used to have the reminders input set out as numbers and then units ... "x" number then "hours" "days" ... etc. For some time it has changed to just having a long scroll- down list which goes through all the numbers and only updates the next reminder to the next number. So 1 hour's next reminder will default to 2 hours. 1 day to 2 days etc The previous method was infinitely more useful. Be good to have it back! ... even if only as an option ...

We never offered such an input method. You must have used a different app. We offer all common reminder times. For everything else there's a custom input. For most use cases our method should be twice as fast.

App's pretty good, but improvements could be made to tasks add-on. I'd love to see a way to add multiple reminders to tasks, and additional way of sorting tasks. Apparently, when you sort tasks by its categories, they seems to be sorted by the date they were added, not the due date of each tasks. Additionally, it would be great if we could sort the order of the categories that appears in the widget.
