No idea whether this is a "how to"request or not. But, unless it is possible to change the time settings on memrise I’m never going to learn Spanish when I wake at 7 in the morning, when I get a reminder/notification on my phone. I swipe to remove the notification icon and get on with my day. 7 is a crazy time and I would love to be able to change myself, or it to be reset to 6pm when there is more chance of success!
You could change your timezone via settings. So you have more time? That’s the best I can think of.
