After more than one rejection by Apple, Peopler has now been approved for sale. If you want to check people’s calendars in MS Exchange without needing Outlook or messing with Shared Calendars, Peopler might be what you’re looking for! It’s free to download and can be upgraded using an In-App Purchase if you like it.
