The standard Week view in Teamup includes a time grid so you can see your calendar events in the correct time slot. All-day events, if any, appear in the box above the time grid:
If you need a Week view without the time grid, it’s easy to get one. You can use the Multi-week view and set it to show 1 week.
To do this, go to Settings > Calendar Views. Scroll to the Multi-Week section. From the drop-down menu, choose 1 for the number of weeks to show. Then return to your calendar and choose the “1 Week” view in the top menu.
You can add a link parameter to hide weekends, if you wish to see this weekly view only for Monday-Friday. See here for details.
