Start and end time of task show on desktop but not in mobile phone app

When I add a start and end time to a task I can see this on my Mac in Safari but the start and end times don't show on my iPhone 4 app. I've made the task reoccurring but that doesn't make a difference. The tasks that have been imported from my iPhone calendar into the Weekplan app on my phone do have the start and end time.

The main reason I would like to see times is that I have a task that I need to do in the morning and also at night. Because they have the same name I can't see on the phone whether I'm ticking off the morning task or the evening task. One option is to rename these tasks but I thought I'd ask whether these start and end times can be switched on on the phone as it is handy to see the times with certain tasks. Thanks
